abstract = {The southernmost Devonian reefs formed along the north-western margin of Gondwana. One of the best-preserved reefal palaeoecosystems of this area is found in the Givetian of Madène el Mrakib (Anti-Atlas; Morocco), exposing a vast, at least ∼1.2 km2 area of reef strata. This contribution documents the ecological succession, taxonomical structure and palaeoecology of this exceptionally diverse reef community. Combined evidence from the sedimentary succession and faunal changes records a trend of progressive shallowing. The ecological succession is characterised by an upsection increase in the abundance and diversity of the reef-building biota, accompanied by a shift in the dominant morphotypes of tabulate corals from platy (pioneering and diversification stages) to branching and massive forms (climax stage). The exceptionally rich, shallow-water reef community occurs in the uppermost part of the succession. The climax community is dominated by extraordinarily large, branching tabulate corals (mostly Thamnopora), with the notable role of massive alveolitid, heliolitid and favositid tabulates, as well as large, solitary rugose corals. A surprising feature of this assemblage is the rather subordinate role of stromatoporoids, generally regarded as a main component of the shallow-water Devonian reefs. Remarkably, the observed community structure is closer to that typical of modern shallow-water reefs, dominated by branching scleractinian corals from the family Acroporidae, than to the archetypal Paleozoic reefs. These distinctive traits of the Madène el Mrakib community make it particularly suitable for comparative studies between Devonian and modern reef ecosystems, showing that these communities shared notable similarities in terms of their ecological successions, zonation patterns, dominance of branching corals and high morphological variability in shallow-water environments, and adaptations of corals to turbulent conditions. © 2023 The Authors},

abstract = {Brachiopod shells coming from the Middle Devonian (latest Eifelian ensensis cono-dont Zone) offshore marly shales deposited on the south-eastern shelf of the Laurussia and cropping out at Skały locality (Holy Cross Mountains; Poland), were investigated with respect to encrusting and bioeroding organisms. These sclerobionts colonized the shells during a time of global warming and eustatic sea-level rise related to the Kačák event. The sclerobiont assemblage is diverse and dominated by colonial ascodictyids and bryozoans, as well as foraminifers, followed by Clionolithes traces and other microb-orings. Sphenothallus cnidarians, Orbiculoidea lingulid brachiopods, and Rothpletzella algae, which are rare or entirely absent in other Devonian sclerobiont communities, are present in Skały. Many brachiopods may have been colonized during life, as sug-gested by the growth patterns of their encrusters close to the shell commissure. However, unequivocal evidence in the form of shell malformations induced by sclerobiont growth is mostly lacking. Conversely, preference of sclerobionts for the convex ventral valve of the productide Poloniproductus suggests that colonization of this host took place post-mortem. The taxonomic composition of the assemblage from Skały is most similar to the rugose coral-hosted sclerobiont assemblage from the Givetian of the nearby locality of Miłoszów and the uppermost Eifelian/lowermost Givetian brachiopod-hosted assemblage from northern Gondwana (Mader Basin; Morocco). It is clearly distinct, how-ever, from Middle Devonian assemblages from the western part of Laurussia (USA) and South China craton. The compositions of the studied sclerobiont assemblages primary reflect specific local habitat conditions and thus their palaeobiogeographic comparisons are still difficult. However, the reliability of such large-scale analyses can be improved by focusing on sclerobiont assemblages hosted by similar groups of organisms and integrating them with well resolved palaeoceanographic reconstructions, as in the case of the Skały and Moroccan assemblages. © 2023 Author(s).},

abstract = {Sclerobionts colonizing brachiopod shells derived from the oldest-known methane seep deposit (upper Silurian; Moroccan Meseta) are reported for the first time. Despite a large number of the brachiopod shells collected, all representing the atrypide species Septatrypa lantenoisi Termier, very few showed the presence of sclerobionts. The majority of the shells were taphonomically altered: worn, exfoliated and corroded. The sclerobionts are represented by cornulitid tentaculitoids and less common auloporid tabulate corals and epibiontic brachiopods. Although the observed assemblage certainly does not reflect the original taxonomic composition of the sclerobiont assemblage, it provides the first insight into the Palaeozoic encrusters inhabiting methane-seep ecosystems. As implied by the moderately 13C-depleted carbon isotope composition and simple, micrite-dominated paragenetic succession of the associated seep carbonates, the investigated community most likely represents a period of slow, diffuse fluid seepage, an interpretation consistent with the common perception of the seep-related brachiopods as non-chemosymbiotic, perhaps opportunistic seep-dwellers unable to colonize sites with more vigorous fluid flow. Likewise, the studied encrusters most likely were non-obligate inhabitants of the seep ecosystem, using the brachiopod shells as firm attachment sites and elevation above the seafloor. This colonization pattern would have probably improved their access to the prolific suspended organic particles and potentially limited their exposure to the highest environmental toxicity. As in the case of geologically much younger serpulid polychaetes, also the cornulitid tubeworms colonized the methane seeps relatively shortly after their first, Middle Ordovician appearance in the fossil record. © 2023 Elsevier B.V.},

abstract = {The mid-Tournaisian Event, also called the Lower Alum Shale Event (LASE), was a global anoxic event that occurred ca. 355 Ma ago. This event is connected to drastic facies changes from pelagic carbonate sedimentation to widespread black organic-rich siliceous shales and radiolarites in many parts of the world. For the first time, high-resolution inorganic geochemistry and framboidal pyrite analyses were applied to decipher depositional condition changes during the mid-Tournaisian anoxic event in the Rhenish Massif, then situated on southern shelf of the Laurussia continent. The lower and middle parts of the LASE interval in the study area were deposited under anoxic conditions at the bottom and water column, while the upper part was deposited under restricted but better‑oxygenated conditions. Additionally, a minor Hg anomaly was found during the LASE deposition in the Rhenish Massif, confirming volcanic overprint during the event. The scenario of palaeoenvironmental changes obtained in the Rhenish Massif is compared to other areas where the LASE was recorded and studied, providing a wider, panregional picture of changes in marine settings during that important Mississippian event. The results obtained in the present study show that the conditions during the LASE in pelagic settings were not uniform, with variable bottom-water oxygenation and different proximity and influence of volcanic activities. The numerous regional magmatic centers are considered as potentially responsible for the drastic depositional changes at a local scale and the bioproductivity increase at the global scale. However, their total contribution caused the climatic turnover responsible for the Gondwana deglaciation and resultant global transgression leading to development of anoxia in many parts of the world during this mid-Tournaisian anoxic event. © 2023 Elsevier B.V.},

abstract = {Monospecific accumulations of ostracods, represented by spine-bearing Janischewskya? sp. and a smooth-shelled Cavellina? sp., were detected inside the body chamber, siphuncle and camerae of three cephalopod specimens (a nautiloid and two goniatites) from the Carboniferous (Mississippian) Cracoean reefs of North Yorkshire, UK. The ostracods occur as isolated valves packed together and are well-preserved, with delicate spines of Janischewskya? sp. still intact on numerous specimens. Such a mode of ostracod preservation inside the cephalopod conchs and their paucity in the surrounding matrix outside the shells indicate that the valves were not concentrated due to sedimentary processes. Rather, the ostracods deliberately entered the empty cephalopod shells in order to seek sheltered habitats for moulting. In the case of the smooth-shelled Cavellina? sp., the ostracod valves preserved inside a camera of the nautiloid have similar size, indicating that a synchronized mass moulting took place in this species. Additionally, the presence of putative eggs closely associated with the spine-bearing Janischewskya? sp. valves inside a siphuncle of the nautiloid shows that the empty conchs could have also served as safe places for egg deposition. The present finds are thus the first examples of cryptic moulting behaviour in ostracods. They also imply that such behaviour in this group of arthropods has a long evolutionary history, at least since the Carboniferous, and potentially may persist in present day ostracods. © 2023 The Palaeontological Association.},

abstract = {The mid-Tournaisian black radiolarian cherts of the Lydiennes Formation are exposed in deep-shelf successions of the Puech de la Suque and Col des Tribes sections of the Mont Peyroux Nappe area in the Montagne Noire, southern France. This interval represents the mid-Tournaisian anoxic event that is also termed the Lower Alum Shale Event. This event is associated with a global marine transgression that was characterized by increased productivity and drastic facies changes from pelagic carbonate sedimentation to the widespread deposition of black organic-rich siliceous shales and radiolarites in many parts of the world. In the present study, high-resolution inorganic geochemistry and framboidal pyrite analyses were employed to decipher changes in depositional conditions during the mid-Tournaisian anoxic event in the Montagne Noire. The results show that the total organic carbon contents of sediments associated with the Lower Alum Shale Event vary from 0.09 to 1.9 wt %. These low to moderate total organic carbon contents, high U/Th, low Corg/P and intermediate V/Cr ratios, enrichment in redox-sensitive trace elements, such as U, Mo and V, as well as varying sizes of pyrite framboids, indicate periodic dysoxic to anoxic bottom-water conditions during deposition of the studied sediments. Anomalous Hg spikes (>500 ppb) are also reported in the mid-Tournaisian deep-water marine succession of the Montagne Noire in the present study, which confirm a possible influence of increased regional volcanic activity during this environmental turnover. © The Author(s), 2023.

abstract = {For the first time, a large number of macrofossils (rugose and tabulate corals; chaetetid sponges and brachiopods) collected from the deposits surrounding a large Middle Devonian (Givetian) reef at Aferdou el Mrakib (Mader Basin; eastern Anti-Atlas; Morocco) were inspected with respect to their sclerobiont assemblages. Although the preservation state of the hosts did not enable us to retrieve precise information on the abundance of the sclerobionts, their general diversity was deciphered and compared to a non-reefal assemblage from the Mader Basin and other reefal assemblages from elsewhere. The sclerobiont inhabitants of the Aferdou el Mrakib reef are diverse, represented by foraminifers, sponges (including stromatoporoids), microconchids, cornulitids, anticalyptraeids, crinoids, brachiopods, rugose and tabulate corals, bryozoans, hederelloids and enigmatic ascodictyids, as well as bioerosion traces after sponges (Clionolithes) and worm organisms (Trypanites borings). Evidently, the diversity of the epibionts is biased toward the robust skeletons, and delicate taxa, such as e.g., ascodictyids and foraminifers, were in most cases taphonomically erased. Additionally, the presence of malformations and bioclaustrations in some of the hosts point to their syn-vivo colonization by now unpreserved mineralized and non-mineralized sclerobionts. Although the sclerobiont assemblages are quite similar on the off-reef rugose corals and reef-front brachiopods, and less diverse on tabulates and chaetetids from the reef-core, when combined together, the whole assemblage shares some similarities with a coeval, non-reef community from the nearby locality of Madène el Mrakib. This pattern may indicate that the sclerobiont species pool was similar to some extent across the Givetian Mader Basin. Circular Oichnus borings, present on some of the brachiopod shells, additionally point to drilling predation and/or parasitism activities in the Aferdou el Mrakib reef habitats. © 2023 Elsevier B.V.},

The absolute majority of symbiotic relationships with serpulids had cnidarian partners (micropredators) in the Mesozoic and Cenozoic. There is no observed escalation in the evolution of symbiotic relationships in serpulids. There may be an optimal frequency of symbiotic relationships for serpulid fauna and when that value was achieved in the Jurassic, it stayed constant during the entire evolution of the group. However, the number of serpulid genera involved in symbiosis increased from the Jurassic (six genera) to the Cretaceous (thirteen genera). It seems that the ability to form symbiotic relationships was in general a useful trait as it spread to various branches of the serpulid phylogenetic tree. © 2023 Informa UK Limited, trading as Taylor & Francis Group.},

abstract = {In the present paper we trace the patterns of convergent evolution of encrusting calcareous polychaetes and tentaculitoids with respect to the morphology and function of their tubes. Both clades have morphologically similar tubes. Six of the eight basic morphotypes of encrusting tubeworms occur both in calcareous polychaetes and in tentaculitoids. All six encrusting tentaculitoid tubeworm morphotypes distinguished have analogues among serpulid and sabellid polychaetes. Both tentaculitoids and polychaetes with calcareous tubes have a similar plesiomorphic morphotype, which is characterized by substrate parallel, irregular growth away from the initial point of encrustation. Dominance of similarities in the order of evolution of morphotypes in the calcareous tubeworms indicates that despite genetic differences, ecological similarities (suspension feeding) and similarities in the tube material (calcareous), as well as body plan (worm-like) had a strong control over the evolution of calcareous tubeworms. The calcareous tubeworm life modes likely appeared in the order of increasing dependence on the type of substrate. In general, possible antipredatory strategies (spines; keels; cryptic and endobiotic mode of life) of calcareous tubeworms are evolutionarily old. The plesiomorphic general hard substrate encrusters are evolutionarily the most successful and have the longest stratigraphic range both in tube-dwelling polychaetes and tentaculitoids. Innovations, such as attachment of the tube by basal projections were developed in some microconchid tentaculitoids but not in calcareous polychaetes; budding tubes occur in both taxa, however, in microconchid tentaculitoids it was a brief evolutionary event, whereas in polychaetes such pseudocolonies have a long stratigraphic range. The ability to live in brackish and fresh waters by some tentaculitoids and tube-dwelling polychaetes seems not to be associated with any particular tube morphotype. © 2023 Elsevier B.V. and Nanjing Institute of Geology and Palaeontology, CAS},

abstract = {Microconchid and anticalyptraeid tubeworms from the Middle Devonian of Morocco are described for the first time. The assemblage, coming from the locality of Madène el Mrakib (Mader Basin; eastern Anti-Atlas), consists of one microconchid species, Palaeoconchus sanctacrucensis, and one new anticalyptraeid species, Anticalyptraea madenensis. Both species encrusted uppermost Eifelian/lowermost Givetian brachiopod shells. P. sanctacrucensis was hitherto only known from the upper Emsian–upper Eifelian of the Holy Cross Mountains, Poland. Thus, its presence in the shelf habitats of northern Gondwana implies its migration from the southern margin of Laurussia during the transgression associated with the late Eifelian Kačák Episode. The encrustation patterns of the brachiopod shells by the Moroccan microconchids indicate that the brachiopods only served as favourable hard substrate for colonisation by the microconchid larvae. However, the occupation of different valves of the same brachiopod by microconchids and Anticalyptraea may imply that both encrusters potentially avoided direct competition for suspended food particles. Characteristics and position of Oichnus borings present on a few microconchids and anticalyptraeids indicate that they were not necessarily formed syn vivo and produced by predatory organisms. It is likely that they were drilled by some tiny suspension-feeders and may represent non-predatory domichnia.urn:lsid:zoobank.org:act:AA095519-5E68-4EDA-B331-E3944F813412. © 2022 Informa UK Limited, trading as Taylor & Francis Group.},

abstract = {Middle Devonian (Eifelian/Givetian transition) brachiopod-hosted sclerobiont assemblage from Gondwana (Morocco; eastern Anti-Atlas; Mader Basin) has been studied for the first time. The analysis of hundreds of brachiopod shells revealed at least 26 sclerobiont taxa, making the studied palaeoecommunity one of the most diverse Middle Devonian sclerobiont assemblage reported to date. The palaeocommunity is dominated by encrusting organisms, in particular bryozoans, foraminifers, ascodictyids and microconchids, whereas bioeroders are represented by Clionolithes and Oichnus ichnospecies. As supported by microfacies, fossil preservation and the presence of encrusting Rothpletzella algae, the sclerobionts developed in a calm, euphotic, offshore marine environment situated below normal wave base. Prevalence of articulated shells without signs of either extensive mineral staining, or taphonomic alteration resulting from hydrodynamic processes, as well as preservation of some delicate encrusters (Vinella; Rothpletzella), indicate that the palaeocommunity did not undergo extensive time-averaging. The hosts were colonized syn vivo, as evidenced by the epibiont growth near the commissure margin, the presence of shell malformations and even embedded auloporid corals and cornulitid tubeworms. Competition for space among sclerobionts was apparently limited, as suggested by the very low number of overgrowth interactions, indicating that the shelly substrate available for colonization was abundant. The presence of the same dominant groups of sclerobionts on different host taxa indicates a lack of species-selectivity by these colonizing sclerobionts. It also suggests that the sclerobiont species pool in the environment was generally similar throughout the deposition of the sampled rock interval. As testified by the host brachiopod and bryozoan species, the sclerobiont assemblage from this locality of northern Gondwana had strong affinities with those from the southern margin of Laurussia, most likely reflecting strong connectivity between these regions provided by the South Equatorial – North Gondwana current system during the late Eifelian Kačák transgressive episode. © 2022 The Author(s)},

abstract = {Incised valley-fill deposits of the Middle Devonian Maywood Formation at Cottonwood Canyon, Wyoming, USA, contains a significant palynological record. Twenty-six palynotaxa were recovered, of which 21 species have wide paleogeographical distribution. The presence of the microspores Samarisporites triangulatus and Contagisporites optivus, as well as other Givetian index taxa, points to a late Givetian age (C. optivus/S. triangulatus palynozone) of the Maywood Formation. The palynoflora investigated may be correlative with the hermanni conodont Zone or a younger zone, and thus they record the latest Taghanic crisis or the earliest post-Taghanic interval. The playnoflora includes progymnosperms that had a tree-like habit (Aneurophytales and Archaeopteridales) characteristic of proximal fluvio-lacustrine settings of floodplains and paralic environments of internal basins. Spores of the herbaceous lycopsid Selaginellales, shrubby lycopods Protolepidodendrales, and primitive ferns, indicate a proximity of terrestrial plant habitats near the Maywood paleovalley. Additionally, the palynofacies (1) have amorphous organic matter and few algal remains of marine origin (Quadrisporites; Dictyotidium), (2) exist in association with assemblages of monospecific microconchid tubeworms that may have colonized non-biomineralized algae, and (3) are in strata that lack other benthic fossils, all of which indicate that the Maywood paleovalley record fluctuations of salinity. These were generated by mixing of marine and freshwater inputs within the estuarine channel, which was developed along the paleoshorelines of the Maywood Sea. © 2022 Elsevier B.V.},

abstract = {A new genus and species of microconchid tubeworm, Aculeiconchus sandbergi n. gen. n. sp., is described from the Givetian (Devonian) Maywood Formation of Cottonwood Canyon, Wyoming, USA. It possesses unique hollow spines of various lengths on the tube underside, a position previously undocumented for these fossils. Like some cyclostome bryozoans possessing basal tubular extensions, the basal spines of Aculeiconchus n. gen. were presumably also used for fixation to flexible substrata, e.g., algal thalli, which is a previously undocumented adaptive strategy in microconchids. Together with other skeletal features, such basal spines could suggest that 'lophophorate' microconchids, unlike the other tentaculitoids, might be phylogenetically not as distant from bryozoans as previously thought. The Maywood Formation, which contains a few-millimeters thick, monospecific shell accumulation of the microconchids described herein, records deposition in an estuarine brackish setting within narrow channels that were cut into underlying strata. The microconchids were opportunistic taxa that repeatedly colonized these salinity-stressed estuarine channels, leading to a series of adaptive innovations, including colonization of plant stems during the Early Devonian (Beartooth Butte Formation) and possibly flexible, soft-algal substrata during the Middle Devonian (Maywood Formation; this study). Tectonic quiescence during the Early and Middle Devonian indicates that erosion and subsequent deposition of the Maywood and the underlying Beartooth Butte Formation channels were responses to major eustatic events. Over a span of nearly 30 Myr, channels were cut successively during lowstand conditions and a distinctive faunal assemblage with microconchids tracked marine transgressions into the channels. © The Author(s), 2021.},

These episkeletobionts form rather a low-diversity community, dominated by microconchid tubeworms, crinoids, and tabulate corals. The last group, however, is especially diverse at the family level, represented by auloporids, alveolitids, coenitids and favositids. These episkeletobionts are considered to have developed in a low-light, lower mesophotic palaeoeonvironment, as evidenced by the presence of platy, alveolitid tabulate coral in the deposits studied. This microconchid-crinoid-tabulate-coral community differs from other Givetian communities from the Holy Cross Mountains (Laskowa and Miłoszów), which also are considered to have developed in low-light hab-itats. The differences in taxonomic composition of episkeletobionts between these three localities most probably resulted from specific local conditions, related to bathymetry (light levels; nutrient levels), the specific nature of the hosts/substrates occupied, and also differences in larval dispersal patterns. This, in turn, shows that vari-ous encrusting communities may have inhabited seemingly similar, marine habitats within a given time interval and neighbouring areas, which may have serious implications for large-scale comparisons of biodiversity within a given palaeoenvironment. © 2022, Polish Geological Society.

abstract = {The middle and upper parts of the Skały Fm, Early to Middle Givetian in age, were investigated in four sections at Miłoszów Wood in the Łysogóry Region (northern region of the Holy Cross Mountains; central Poland). The dating is based on conodonts (Polygnathus timorensis Zone to the later part of the Polygnathus varcus/Polygnathus rhenanus Zone; early Polygnathus ansatus Zone cannot be excluded) and spores (Ex1–2 subzones) and, coupled with cartographic analysis and geophysical investigation, allows correlation within the strongly faulted succession. Significant lateral facies variations within the carbonate ramp depositional system in comparison with the better studied Grzegorzowice–Skały section, about 3 km distant, are documented, thanks to conodont-based correlation of both successions. Foraminifers, fungi, sponges, rugose and tabulate corals, medu-sozoans, microconchids and cornulitids, polychaetes (scolecodonts), molluscs (bivalves; rostroconchs; and gas-tropods), arthropods (trilobites and ostracods), bryozoans, hederelloids, ascodictyids, brachiopods, echinoderms (mostly crinoids; rare echinoids; holuthurians; and ophiocistoids), conodonts, fish, plants (prasinophytes; chloro-phycophytes; and land plant spores), and acritarchs are present. Brachiopods are the most diverse phylum present (68 species), other richly represented groups are bryozoans and echinoderms; in contrast, cephalopods and trilobites are low in diversity and abundance. The muddy, middle to outer ramp biota (200 marine taxa; including 170 species of marine animals; 22 photoautotrophs; 6 forams) represents a mixture of allochthonous shallower-wa-ter communities (upper BA3), including storm-and possibly tsunami-affected coral mounds, and autochthonous deep-water soft-bottom brachiopod (e.g.; Bifida–Echinocoelia) communities (BA 4–5). The richness and diversity of the Miłoszów biota is relatively high, comparable with other approximately coeval pre-Taghanic ecosystems during the Devonian climatic deterioration (cooling). Preliminary data indicate that in the Holy Cross Mountains, no large-scale replacement of brachiopod (and probably many other benthic ones; like crinoids) communities took place between the Early–Middle Givetian and the Early Frasnian, in contrast to the demise of the Hamilton/ Upper Tully fauna in the Appalachian Basin. Such a similarity of pre-and post-Taghanic faunas does not exclude the occurrence of environmental perturbations and transient community turnovers, caused by immigrations during the Taghanic Biocrisis, but evidences the successful recovery of the indigenous biota. © 2022, Polish Geological Society.

abstract = {This study describes diverse assemblages of serpulid and sabellid polychaetes from various Middle and Upper Jurassic (upper Bajocian to lower Kimmeridgian) deposits of the Polish Basin. Twenty four taxa are reported in total, including two new species (Cementula radwanskae sp. nov. and Filogranula spongiophila sp. nov.). Abundance, distribution, and colonization patterns of serpulids and sabellids significantly depended on many palaeoenvironmental variables including the nature of the colonized substrate and its overall shape, food supply, and hydrodynamism. The most diverse assemblages have been noted on the Middle Jurassic shells inhabiting soft muddy substrates, on hardgrounds and oncoids, whereas the lowest biodiversity levels have been found on the Middle Jurassic hiatus concretions and Kimmeridgian oyster shell beds. Some species are clearly associated with certain substrate types, whereas stratigraphic interval is not that important. Middle Jurassic mobile rockgrounds (hiatus concretions and oncoids) and hardgrounds are characterized by the most similar species associations, while Middle Jurassic shelly substrates from soft-bottom environments and Upper Jurassic shell beds and sponge build-ups are most dissimilar with respect to the colonizing tube dwelling polychaete taxa. Among the diverse assemblages of the encrusting faunas, serpulid and sabellid tubeworms are the most abundant constituents in the majority of settings, what is explained by their opportunism and ability to effectively outcompete other contenders. In the majority of locations, the most abundant tube-dwelling polychaete is the ubiquitous sabellid Glomerula gordialis, followed by the serpulid species Propomatoceros lumbricalis. The dominance of these species is congruent with many other serpulid and sabellid communities inhabiting various Jurassic palaeoenvironments. Copyright © 2022 J. Słowiński et al.},

This tentaculitoid shares common structural features (inwardly directed pseudopunctae and vesicles) with Anticalyptraea, but differs from the latter in having a spirally coiled, microconchid-like shell with a variously oriented aperture, thin and sharp transverse ridges and lacking an inverted cone-like morphology. Unlike other tentaculitoids (microconchids; trypanoporids; cornulitids), these encrusters, unique with respect to morphology and shell structure, have so far not been taxonomically classified at the ordinal level. Now, taking into account that such tentaculitoids are taxonomically and morphologically more diverse than previously assumed, we propose to include them in a separate order Anticalyptraeida. Unlike microconchids and cornulitids, anticalyptraeids are the least studied group of tentaculitoids and thus poorly recognized. In part, this may be due to their misidentification with associated spirally coiled microconchids, to which anticalyptraeids are very similar at juvenile stages. http://www.zoobank.org/lsid:zoobank.org:act:C1E9D9A4-555E-4F5A-BEDC-8046CCA58BD9. © 2022 Geologiska Föreningen.},

abstract = {Palaenigma wrangeli (Schmidt) is a finger-sized fossil with a tetraradiate conical skeleton; it occurs as a rare component in fossiliferous Upper Ordovician strata of the eastern Baltic Basin and is known exclusively from north Estonia. The systematic affinities and palaeoecology of P. wrangeli remained questionable. Here, the available specimens of P. wrangeli have been reexamined using scanning electron microscopy and x-ray computed tomography (microCT). Additionally, the elemental composition of the skeletal elements has been checked using energy dispersive X-ray spectroscopy. The resulting 2D-, and 3D-scans reveal that P. wrangeli consists of an alternation of distinct calcium phosphate (apatite) lamellae and originally organic-rich interlayers. The lamellae form four semicircular marginal pillars, which are connected by irregularly spaced transverse diaphragms. Marginally, the diaphragms and pillar lamellae are not connected to each other and thus do not form a closed periderm structure. A non-mineralized or poorly mineralized external periderm existed originally in P. wrangeli but is only rarely and fragmentary preserved. P. wrangeli often co-occurs with conulariids in fossil-rich limestone with mudstone–wackestone lithologies. Based on the new data, P. wrangeli can be best interpreted as a poorly mineralized conulariinid from an original soft bottom habitat. Here the new conulariinid family Palaenigmaidae fam. nov. is proposed as the monotypic taxon for P. wrangeli. Copyright 2021 Kröger et al.},

The LASE part of the section, unlike older Tournaisian deposits, is characterised by high concentrations of isorenieratane, palaeorenieratane, and their diagenetic derivatives, the occurrence of 2-methyl-3-iso-butyl-maleimides, and high values of the sterane-to-hopane ratio. The predominance of tiny pyrite framboids, inorganic data such as low values of the Th/U and high values of the Corg/P and V/Cr ratios, and generally higher enrichments of redox-sensitive metals such as U, V, Mo, Pb, and Zn and depletion in Mn, all suggest anoxic/euxinic conditions on the sea-bottom. The results of our investigations, especially Co, Mn, Cd, and Mo distribution patterns, demonstrate that enhanced primary productivity in the water column was responsible for a high degree of organic carbon burial rather than preservation in restricted conditions on the seafloor. This elevated productivity may have been generated by the upwelling of nutrient-rich deep water, an increase in volcanic activity and volcanogenic oceanic fertilisation, or both. Volcanically driven mid-Tournaisian climatic changes (warming), as manifested by high Zr concentrations and Hg anomalies, may have been responsible for the deglaciation of Gondwana resulting in the global crenulata transgression. The global rise in sea level and high level of organic productivity were responsible for the development of anoxic conditions and the halt of carbonate production, as reflected by drastic changes of facies not only in the sections investigated, but in many other parts of the world as well. © 2021 Elsevier B.V.},

abstract = {The coexistence of sessile, tube-dwelling polychaetes (serpulids) and hydroids, has been investigated. Serpulid tubes bearing traces after hydroids are derived from different stratigraphic intervals spanning the Middle and Upper Jurassic, the rocks of which represent the diverse paleoenvironments of the Polish Basin. Although fossil colonial hydroids classified under the species Protulophila gestroi are a commonly occurring symbiont of these polychaetes during the Late Cretaceous and Cenozoic, they seem to be significantly less frequent during the Jurassic and limited to specific paleoenvironments. The hydroids described here are represented by traces after a thin stolonal network with elongated polyp chambers that open to the outer polychaete tube’s surface with small, more or less subcircular apertures. Small chimney-like bulges around openings are an effect of the incorporation of the organism by in vivo embedment (bioclaustration) within the outer layers of the calcareous tube of the serpulid host. Considering the rich collection of well-preserved serpulid tubes (>3000 specimens), the frequency of bioclaustrated hydroids is very low, with an infestation percentage of only 0.6% (20 cases). It has been noticed that only specimens of the genus Propomatoceros from the Upper Bajocian, Lower Bathonian, Middle Bathonian, and Callovian have been found infested. However, the majority of bioclaustrated hydroids (17 cases) have been recorded in the Middle Bathonian serpulid species Propomatoceros lumbricalis coming from a single sampled site. Representatives of other genera are not affected, which is congruent with previous reports indicating that Protulophila gestroi was strongly selective in the choice of its host. A presumably commensal relationship is compared with the recent symbiosis between the hydroids of the genus Proboscidactyla and certain genera of sabellid polychaetes. © 2020 Słowiński et al.

abstract = {The end-Devonian global Hangenberg event (359 Ma) is among the most devastating mass extinction events in Earth’s history, albeit not one of the “Big Five”. This extinction is linked to worldwide anoxia caused by global climatic changes. These changes could have been driven by astronomical forcing and volcanic cataclysm, but ultimate causes of the extinction still remain unclear. Here we report anomalously high mercury (Hg) concentration in marine deposits encompassing the Hangenberg event from Italy and Austria (Carnic Alps). The Hangenberg event recorded in the sections investigated can be here interpreted as caused by extensive volcanic activity of large igneous provinces (LIPs), arc volcanism and/or hydrothermal activity. Our results (very large Hg anomalies) imply volcanism as a most possible cause of the Hangenberg event, similar to other first order mass extinctions during the Phanerozoic. For the first time we show that apart from anoxia, proximate kill mechanism of aquatic life during the event could have been methylmercury formed by biomethylation of a volcanically derived, huge concentration of inorganic Hg supplied to the ocean. Methylmercury as a much more toxic Hg form, potentially could have had a devastating impact on end-Devonian biodiversity, causing the extinction of many pelagic species. © 2020, The Author(s).},

abstract = {Middle Devonian (Givetian) rugose corals from the Holy Cross Mountains (Miłoszów), Poland, have been analysed with respect to epibiont colonization patterns. Solitary microconchid tubeworms and colonial bryozoans, hederelloids and ascodictyids numerically dominate on the coral hosts. Moreover, the same taxonomic groups of epibionts dominate both the larger (Heliophyllum; Acanthophyllum; Stringophyllum; Ceratophyllum; Cystiphylloides) and smaller (Thamnophyllum) corallites, indicating the true pattern of epibiosis was achieved. The presence of common bioclaustrated epibionts, constricted and rejuvenated coral calyces, as well as epibionts growing concordantly with the host's growth direction, indicate that at least some corals were colonized during life. The observed low number of overgrowth cases of various epibionts on coral hosts suggests, that competition for hard substrate was negligible, most probably due to abundant coral substrates on muddy sea-bottom of the Givetian sea at Miłoszów. This epibiont community is similar to other known Devonian encrusting communities which likely developed in a more nutrient-rich palaeoenvironments and differs markedly from taxonomically-poor assemblages developing in a more oligotrophic conditions. The presence of Rothpletzella encruster, which is considered to be related to green algae, indicates that the Miłoszów coral community dwelled within the limits of the photic zone. © 2020 Elsevier B.V.},

abstract = {Analysis of mushroom-shaped rugose corals Schlotheimophyllum patellatum (Schlotheim; 1820) from the Silurian (Upper Visby Beds; Lower Wenlock; Sheinwoodian) of Gotland, Sweden, showed that they were colonized on both the upper (exposed) and lower (cryptic) sides by a variety of encrusting and boring (sclerobiont) biotas, represented by 10 taxa and at least 23 species. Bryozoans and microconchid tubeworms, the most abundant encrusters, dominated on the cryptic undersides of the corals, while the dominant endobionts responsible for Trypanites borings overwhelmingly dominated the exposed surfaces. Except for cnidarian sphenothallids, which were exclusive colonizers of the underside of only one coral host, no other encrusters could be referred to as obligate cryptobionts. Because the upper surface of these corals was likely covered by soft-tissues during life, in specimens lifted off the sea-floor sclerobionts must have settled on the cryptic sides first. They could colonize the upper side only after the coral’s death, unless it was covered by sediment as could be the case in some flat specimens. With time, the space on the underside of the coral skeleton may have progressively been filled by sediment as well, precluding further colonization by sclerobionts. In that respect, the colonization patterns of these corals by encrusters and borers were controlled by the complex interplay of environmental factors, sclerobiont dynamics and coral growth in a given Silurian habitat. Compared with Silurian stromatoporoid hosts, the sclerobiont diversity and abundance noted on the Schlotheimophyllum corals may be regarded as representative for the Silurian as a whole. © 2020 Lethaia Foundation.

The fossils are pyritized, have fan-shaped morphologies and are formed by tightly-packed branches which divide dichotomously at different points in their development. The organisms preserved grew horizontally on shelly substrates. Comparisons with similar fossils known from the literature indicate that they do not represent any animal taxon commonly encrusting hard substrates. Instead, the morphology, organization and growth mode of these fossils are most similar to microfossils known under the name Rothpletzella, which so far have only been known from thin sections. Rothpletzella is a problematicum for which algal affinities have been proposed. The preserved branches of the fossils described here are too large for cyanobacterial cells. Their large size suggests their placement, along with other described Rothpletzella fossils, within the green algae order Bryopsidales. It is suggested that originally, these organisms possessed thalli encased within a thin, delicate calcified sheath. After burial the thalli underwent pyritization via sulphate reduction mediated by bacterial activity within low pH, dysoxic microenvironment, and their sheath dissolved. As three-dimensionally preserved, these algae provide a new, previously unrecognized, component within the Devonian encrusting communities. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.},

abstract = {The lowermost Famennian deposits of the Kowala quarry (Holy Cross Mountains; Poland) are becoming famous for their rich fossil content such as their abundant phosphatized arthropod remains (mostly thylacocephalans). Here, for the first time, palaeontological and geochemical data were integrated to document abundance and diversity patterns in the context of palaeoenvironmental changes. During deposition, the generally oxic to suboxic conditions were interrupted at least twice by the onset of photic zone euxinia (PZE). Previously, PZE was considered as essential in preserving phosphatised fossils from, e.g., the famous Gogo Formation, Australia. Here, we show, however, that during PZE, the abundance of arthropods drastically dropped. The phosphorous content during PZE was also very low in comparison to that from oxic-suboxic intervals where arthropods are the most abundant. As phosphorous is essential for phosphatisation but also tends to flux off the sediment during bottom water anoxia, we propose that the PZE in such a case does not promote the fossilisation of the arthropods but instead leads to their impoverishment and non-preservation. Thus, the PZE conditions with anoxic bottom waters cannot be presumed as universal for exceptional fossil preservation by phosphatisation, and caution must be paid when interpreting the fossil abundance on the background of redox conditions. © 2019, The Author(s).},

However, the present study shows that it is not a serpulid polychaete but a cornulitid with a microlamellar shell microstructure. Both Upper Devonian cornulitids are devoid of pseudopunctae and vesicular wall structures; the absence of the former in these species presumably does not constitute a useful adaptation. The greatest number of cornulitid species occurs in the Lower Devonian; their numbers seem to be lower in the Middle and Upper Devonian than in the Ordovician and Silurian.

abstract = {In this paper, uppermost Jurassic and Lower Cretaceous black organic-rich siltstones (Rurikfjellet Formation) from Carolinedalen (Isfjorden; Spitsbergen) are studied using integrated palynological, petrographic, and geochemical methods (organic and inorganic geochemistry as well as Rock-Eval pyrolysis) in order to decipher the depositional conditions prevailing during their sedimentation, the type of organic matter from which they were formed, and their potential for generating hydrocarbons. The age of these investigated sediments encompasses an interval from the upper Tithonian-Berriasian to the Hauterivian, dated on the basis of dinocyst biostratigraphy. The ammonoids found in loose form at the base of the investigated section, such as Laugeites groenlandicus, are indicative of the upper part of the middle Tithonian. Based on palynology, biomarkers, and Rock-Eval data, the kerogen in the investigated siltstones from Isfjorden is of the mixed II/III type; the organic matter is mixed marine and terrestrial in origin, and represents the early to peak ‘oil window’ maturation stage (Tmax around 440 °C). These siltstones were deposited under a high-productivity regime with oxic/dysoxic bottom water conditions, as evidenced from the size distribution of pyrite framboids, in which pyrites with diameters >5 μm predominate. Values of Th/U and Corg/P ratios generally above 3 and 30, respectively, along with pristane/phytane ratios >2 and sterane/hopane ratios <0.3, also indicate oxic to suboxic sedimentary conditions in the water column. Anoxia, if present, must have been short-lasting and formed oxygen minimum zone in the water column. Elevated productivity in the photic zone may have been generated by an increase in volcanic activity, as confirmed by higher Hg contents and/or terrigenous nutrient supply. © 2018 Elsevier Ltd},

abstract = {Marine benthic ecosystems collapsed during the catastrophic end-Permian mass extinction, and subsequently endured a protracted phase of biotic recovery under harsh environmental conditions. In particular, metazoan reef communities almost totally disappeared and were replaced by microbe-dominated mounds during the latest Permian–earliest Triassic. Here we report the stratigraphically oldest exclusively metazoan bioconstructions from earliest Triassic (mid-Induan) strata in East Greenland — these formed within the first ca 300 ka after the Permian-Triassic boundary. Unlike the multitaxic sponge-microbe and bivalve-based buildups recorded from the Early Triassic peri-paleoequatorial Panthalassan and Tethyan margins, the East Greenland bioaccumulations developed within a restricted Boreal mid-paleolatitude seaway, and comprised a monospecific primary framework of microconchid ‘lophophorate’ tubes with shell fragments and phosphatic debris cemented by biogenic calcite. Prostrate growth of the microconchids likely facilitated their accretion into successive sheet-like biostromes and small bioherms. These are associated with a regional paleoenvironmental shift towards well‑oxygenated bottom waters, and locally punctuated sedimentation that created a favorable habitat. Although microconchids were both abundant and geographically widespread throughout the earliest Triassic, such buildups formed solely by these metazoans have not been reported from that time frame outside the Boreal Realm. These apparently flourished in the absence of more stable complex communities, and suggest that a locally variable, rather than ubiquitously sequential revival of metazoan bioconstruction activity took place in the immediate aftermath of the end-Permian extinction. However, these may also suggest that ecological recovery of benthic marine ecosystems following the end-Permian mass extinction might have started earlier in higher paleolatitudes. © 2018 Elsevier B.V.},

abstract = {The Middle Devonian (Givetian) chaetetid sponges and alveolitid tabulate corals that inhabited mesophotic paleoenvironments of the southern shelf of Laurussia (Holy Cross Mountains; Poland) have been studied with respect to encrustation patterns. These epibiotic communities are characterized by modest diversity and high dominance, and show distinct polarization with respect to the exposed and cryptic sides of the host's skeletons. The most abundant davidsoniid brachiopods and microconchids show strong preferences toward the lower (cryptic) sides, while auloporid tabulate corals dominate on the exposed sides of the hosts. The remaining and much rarer epibionts, cornulitids and rugose corals, show no clear preferences. In some shallow-water Silurian paleoenvironments, auloporids are known to dominate the cryptic sides of the hosts. Thus, considering the auloporid tabulates as photosymbiotic corals, their absence or rarity in the Middle Devonian cryptic habitats might have resulted from insufficient irradiance levels in otherwise depleted light conditions. As a result, the available space and lack or lower competition for the area with faster-growing colonial auloporids, enabled solitary encrusters to colonize the cryptic niches. The scarce bioerosion traces and rather low diversity of epibionts in our case may indicate that these mesophotic reefs developed in a nutrient-poor, oligotrophic habitats. The davidsoniid-dominated, cryptic encrusting communities were widespread in some paleoenvironments during the Middle Devonian, being known from both Laurussia and South China craton. However, such mesophotic cryptic communities, characterized by distinct polarization in comparison to open-surface environments, contrast with other Givetian deep-water, aphotic cryptic communities reported so far, where such polarization is hardly visible. © 2018 Elsevier B.V.},

Tube microstructures of Anamobaea orstedi, Notaulax tenuitorques, and Notaulax sp. nov. are described. The studied sabellid tubes have three different types of microstructure. Most simple is irregular mesh microstructure which is composed of thin, long, and variously curved fibers of somewhat chaotic orientation (Notaulax tenuitorques). The irregular mesh microstructure could be plesiomorphic among sabellid tube structures. Oriented fibers in homogeneous matrix microstructure involves some kind of chemical control mechanisms that asserts the same orientation of all fibers (Notaulax sp. nov.). Anamobaea orstedi shows the most advanced pattern, a regular plywood structure, which is composed of thin subparallel or parallel to each other fibers that have different orientation in adjacent lamellae. Regular plywood structure has apparently greatest strength among organic tube structures of sabellids combined with good flexibility. Organic sabellid tube microstructures are likely species specific and have a taxonomic value. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.},

abstract = {The Judith River Formation of Montana, USA, renowned for its preservation of Late Cretaceous dinosaurs, now yields the oldest-known evidence of trematode parasitism of bivalves. Highly distinctive igloo-shaped traces found on shells of the freshwater bivalve Sphaerium are virtually identical to igloo-shaped traces known from living marine bivalves infected by metacercaria larvae of gymnophallid trematodes (flatworms). This unique record of paleoparasitism provides key insights into the evolution of an important parasite group, reveals the inner workings of cryptic ecological associations, and enriches our understanding of ancient food webs. Our discovery extends the record of trematode-bivalve interaction back to the Late Cretaceous (ca. 76 Ma), and indicates that this parasite-host relationship was established in freshwater ecosystems much earlier than previously surmised. The complex multi-host lifecycles of modern trematodes and the general stability of parasite-host associations suggest that sphaeriid bivalves in the Judith River record likely served as the second intermediate host. Potential candidates for the definitive host range from molluscivorous fish to birds and non-avian predatory dinosaurs. With the history of trematode-bivalve interaction pushed back to the Late Cretaceous, patterns in trematode infection can now be interrogated across major episodes of global change, including the Cretaceous-Paleogene mass extinction and the Paleocene-Eocene thermal maximum. © 2018 Geological Society of America.},

abstract = {Upper Devonian brachiopods from the Central Devonian Field, Russia have been investigated with respect to encrustation patterns of cornulitids. These Palaeozoic encrusters were very characteristic component of shelly substrates during the Devonian and may serve as valuable objects for palaeoecological studies, especially those concerning the encrusters-host relationships. On the basis of rich material, it has been shown that cornulitid abundance significantly increased in the lower Famennian. Their disparity also increased from one morphotype (robust) present in the upper Frasnian to two distinct morphotypes (robust and slender; presumably representing two different species) in the lower Famennian. The analysis of the spatial occurrence of cornulitids on two dominant lower Famennian brachiopod species (Cyrtospirifer zadonicus and Ripidiorhynchus huotinus) showed, that these encrusters preferred the marginal parts of the shells. This, together with a dominant directional growth of cornulitids toward the commissure, indicates that cornulitids benefited from food brought by feeding currents produced by the brachiopod's lophophore. The unequivocal evidence for syn vivo association of the cornulitids and their brachiopod hosts is the presence of distinct shell malformations caused by cornulitid growth affecting the host's shell-secreting epithelium, preserved on some lower Famennian specimens. Interestingly, these malformations were caused by a slender cornulitid morphotype only. Thus, it is evident that during food gathering from the inhalant currents, this cornulitid species exerted a distinct, negative effect on the brachiopod – a deviation of its shell growth. In this case, we may consider this particular cornulitid species as ectoparasite rather than commensal with respect to its host. © 2018 The Geologists’ Association},

abstract = {The cuticle of concavicarids (Arthropoda: Thylacocephala) from the early Famennian (Upper Devonian) of the Holy Cross Mountains, Poland was studied with respect to its microstructural details. Investigated laminated cuticle with phosphatic/organic composition, possesses two different kinds of microstructure with assumed sensory functions. The first kind consists of circular depressions, each located in the central area of characteristic polygons forming the carapace exterior ornamentation. These depressions are interpreted as sealed during phosphatisation processes setal lumens. The second kind occurs exclusively in carapace margins. These intracuticular microstructures occur as elongated tubular structures, circular to oval in cross section, penetrating the cuticle interior but not reaching its surface. They form a thin belt with a kind of ‘sensory fields’ on the dorsum and a wider belt in the ventrocaudal part of the carapace. These belts are connected in the rostral and caudal area, forming a continuous sensory zone encompassing each valve. These structures are very similar to crustacean organule canals, and the dorsally situated ‘sensory fields’, suggest some similarity to crustacean sensory dorsal organs. This possible sensory system is the oldest of this kind found in Thylacocephala. Its morphology and presumed canal walls mineralogical composition suggests crustacean affinity of Thylacocephala. © 2017 Informa UK Limited, trading as Taylor & Francis Group.},

abstract = {In this study we focused on the dynamics of encrusting assemblages preserved on brachiopod hosts collected from upper Frasnian and lower Famennian deposits of the Central Devonian Field, Russia. Because the encrusted brachiopods come from deposits bracketing the Frasnian/Famennian (F/F) boundary, the results also shed some light on ecological differences in encrusting communities before and after the Frasnian-Famennian (F-F) event. To explore the diversity dynamics of encrusting assemblages, we analyzed more than 1300 brachiopod valves (substrates) from two localities. Taxon accumulation plots and shareholder quorum subsampling (SQS) routines indicated that a reasonably small sample of brachiopod host valves (n=50) is sufficient to capture the majority of the encrusting genera recorded at a given site. The richness of encrusters per substrate declined simultaneously with the number of encrusting taxa in the lower Famennian, accompanied by a decrease in epibiont abundance, with a comparable decrease in mean encrustation intensity (percentage of bioclasts encrusted by one or more epibionts). Epibiont abundance and occupancy roughly mirror each other. Strikingly, few ecological characteristics are correlated with substrate size, possibly reflecting random settlement of larvae. Evenness, which is negatively correlated with substrate size, shows greater within-stage variability among samples than between Frasnian and Famennian intervals and may indicate the instability of early Famennian biocenoses following the faunal turnover. The occurrence distribution of encrusters points to nonrandom associations and exclusions among several encrusting taxa. However, abundance and occupancy of microconchids remained relatively stable throughout the sampled time interval. The notable decline in abundance (~60%) and relatively minor decline in diversity (~30%) suggest jointly that encrusting communities experienced ecological collapse rather than a major mass extinction event. The differences between the upper Frasnian and lower Famennian encrusting assemblages may thus record a turnover associated with the F-F event. © Copyright 2017 The Paleontological Society.

abstract = {Here, the Lower Permian, post-glacial fossiliferous Lontras black shales from the Paraná Basin (southern Brazil) are studied using integrated palynological, geochemical and petrographic methods for the first time in order to decipher the prevalent palaeoenvironmental conditions during their sedimentation. These black shales were deposited in a restricted marine environment. Inorganic geochemical data (U/Th ratios, authigenic uranium, molybdenum), organic geochemical data (total organic carbon, biomarkers) and framboid pyrite size distributions point to predominantly anoxic/euxinic bottom-water conditions. Moreover, the presence of aryl isoprenoids and maleimide biomarkers indicates that euxinia in the water column was intermittently present in the photic zone. The onset of anoxic conditions was caused by elevated productivity in the basin, which was related to deglaciation, marine transgression and the increased delivery of terrestrial nutrients. The presence of a positive organic carbon isotope excursion indicates that the black shale deposition resulted from increased productivity and the expansion of anoxic and nitrogen- and phosphate-enriched waters into the shallow photic zone. The high values of δ15N (exceeding 9‰) may be related to the deglaciation-driven sea-level rise and advection of denitrified water mass from the Panthalassic Ocean to the intracratonic Paraná Basin. Prolonged periods of sea-floor anoxia/euxinia excluded potential scavengers and bioturbators, thus enhancing the preservation of numerous fossil taxa, including fish, sponges, insects and their larval cases, and conodont apparatuses. The intermittent photic zone euxinia may also have contributed to the mass mortality of fish populations, the fossils of which are very well-preserved in these black shales. © 2017 Elsevier B.V.},

abstract = {A family-level classification of microconchid tubeworms (Order Microconchida; Class Tentaculita) is proposed here for the first time. Based on distinct tube microstructure and/or tube ontogeny, the following families are defined: Palaeoconchidae (tubes having microlamellar structure deflected by pseudopunctae), Microconchidae (tubes having microlamellar structure deflected by punctae that are manifested on the tube exterior as distinct pores), Helicoconchidae (tubes showing lateral budding and binary fission budding), and Punctaconchidae (tubes having microlamellar structure deflected by large punctae manifested on the tube exterior by large; distinct pores). This classification is necessary because it enables us to place specific genera within particular families based on shared unique external and internal features. This family-level classification also helps distinguish morphologically convergent forms and allows for potential recognition of phyletic relationship among different genera and species. Additionally, two new genera (Tuberoconchus and Spinuliconchus), as well as one new species (Spinuliconchus biernatae) from the Lower Devonian (Emsian) of the Holy Cross Mountains, Poland are erected. http://zoobank.org/urn:lsid:zoobank.org:pub:50DC23F6-93A7-4B0A-B7F7-6C7667D4F6FB. © 2016 Informa UK Limited, trading as Taylor & Francis Group.},

abstract = {The sedimentary succession in central Poland records significant changes in facies at the turn of the Planula and Platynota zones in the Upper Jurassic, expressed by the drowning of the ramp-type platform and development of an extensive isochronous marl horizon. The topmost level of the marl horizon is a regional hardground, which is interpreted as the third-order sequence boundary Kim 1. In some areas, the hardground was eroded and is only preserved as bored and encrusted clasts. The composition of the borings may indicate that colonization and recolonization of the clasts took place in an extremely shallow water environment. The overall low level diversity of clast-encrusting organisms and their occurrence on both sides of clasts indicates frequent overturning and high current activity. However, other extrinsic factors, such as salinity fluctuations, may have been involved. The final redeposition and burial of the clasts were related to subsidence through widespread reactivation of Paleozoic faults. Comparison with Middle Oxfordian–Lower Kimmeridgian sequences of central and southern Poland indicates that the carbonate ramp morphology and paleoenvironmental conditions were periodically subjected to significant modification during phases of extensional tectonics, with the development of fault-controlled intra-platform ridges and basins. These features may have been the NE continuation of parallel swells and basins developed in the southern part of the carbonate platform adjacent to the Tethys. © 2017, The Author(s).},

The ornamentation patterns and characteristics of the exoskeleton indicate that the conulariids, represented by at least two incomplete specimens, belong to a single species within the genus? Paraconularia. Some Polish Ordovician fossils previously described as conulariids either do not possess morphological characters seen in conulariids, or are too fragmentary to be confidently assigned to conulariids. Therefore, the fossils reported here not only represent the first documented record of conulariids in the Devonian of Poland, but the first true conulariids ever reported and illustrated from Poland. The exoskeleton of one specimen possesses at least three sublethal injuries. As the host deposit of marly shale originated in deep water, it is possible that the injuries did not result from purely physical factors, but rather from attempted predation. This interpretation is consistent with the fact that the lower Famennian deposits at Kowala preserve other predation-related structures such as fish coprolites, fragmented arthropod cuticle and regurgitated remains. © 2017 The Geologists' Association},

The characteristic morphology, consisting of a flat attachment base and convex upper hemisphere possessing an apical, tiny, circular opening indicate that these structures represent gastropod (possibly Caenogastropoda) egg capsules. Originally, the egg capsules were attached to the empty shells of the ammonites Deshayesites and Sinzovia which later were embedded within carbonate concretions. The preservation of the egg capsules resulted from both their deposition within a suitable, cryptic habitat provided by the empty ammonite shells, and the quick cementation of the infilling sediment which not only sufficiently protected the capsules from external environment, but also created a suitable, closed microenvironment for fossilization. The calcitization of the egg capsules may have occurred under low pH conditions in an environment characterized by a very low concentration of phosphorous ions essential for phosphatization. So far, such structures are known from a few examples derived from different stratigraphic horizons and geographic locations. Those which are known have been reported in the form of pyritized, phosphatized, carbonaceous and even bioimmured fossils. The calcitized gastropod egg capsules presented here indicate, that such structures may in fact be preserved by a wide array of fossilization modes in different paleoenvironments/microenvironments.

abstract = {Asphinctites tenuiplicatus [M] and Polysphinctites secundus [m] from the Asphinctites tenuiplicatus Zone (Early Bathonian), are usually considered as a sexual dimorphic pair, although authors describe them as separate species. We used statistical methods to test the sexual dimorphic correspondence between those morphospecies, based on a rather large sample of well-preserved macro- and microconchs derived from a single horizon of calcareous concretions in the Polish Jura. Our results indicate that both dimorphs or sexes have identical ontogeny up to a critical diameter, from which they diverge towards the characteristic morphology and sculpture of each dimorph. Thus, both dimorphs are described as a single species: Polysphinctites tenuiplicatus [M and m]. After review of the several nominal species usually assigned to the genera Asphinctites and Polysphinctites throughout their stratigraphic and biogeographic range in the Early Bathonian of the Tethys, it is concluded that they actually correspond to only two species of a single lineage. The corresponding name for the lineage should be Polysphinctites (= Asphinctites as a junior synonym). © 2016 H. Parent and M. Zatoń.},

abstract = {More than 10,000 non-marine microconchid tubeworms (order Tentaculita) from the Lower Carboniferous (Mauch Chunk Group) of West Virginian, USA, have been inspected with respect to the occurrence of specimens having repaired injuries. The inspection showed that only nine specimens bear distinct regenerations of their tubes which constitute only 0.08% of the total specimens. This value, although much lower than that obtained from other encrusting tentaculitoid tubeworms, is very similar to that calculated before for the thousands of Early Devonian planktonic tentaculitids. This clearly indicates that sample size (specimen number) is critical for obtaining the reliable data about the proportion of regenerated vs. unaffected specimens. The sublethal injuries present in these few individuals probably resulted from failed predation, most probably by grazing fishes. However, the repaired injuries only indicate that some individuals survived but do not provide any information about the predation intensity on the group in the given paleoenvironment. Microconchids encrusted a given substrate in large quantities, so grazing fishes may have easily removed the majority of individuals, leaving no trace of predation activity in the Early Carboniferous, non-marine paleoenvironments of what is now West Virginia. © 2015 Taylor & Francis.},

abstract = {The end-Permian mass extinction constituted the most devastating biotic crisis of the Phanerozoic. Its aftermath was characterized by harsh marine conditions incorporating volcanically induced oceanic warming, widespread anoxia and acidification. Bio-productivity accordingly experienced marked fluctuations. In particular, low palaeolatitude hard substrate communities from shallow seas fringing Western Pangaea and the Tethyan Realm were extremely impoverished, being dominated by monogeneric colonies of filter-feeding microconchid tubeworms. Here we present the first equivalent field data for Boreal hard substrate assemblages from the earliest Triassic (Induan) of East Greenland. This region bordered a discrete bio-realm situated at mid-high palaeolatitude (>30°N). Nevertheless, hard substrate biotas were compositionally identical to those from elsewhere, with microconchids encrusting Claraia bivalves and algal buildups on the sea floor. Biostratigraphical correlation further shows that Boreal microconchids underwent progressive tube modification and unique taxic diversification concordant with changing habitats over time. We interpret this as a post-extinction recovery and adaptive radiation sequence that mirrored coeval subequatorial faunas, and thus confirms hard substrate ecosystem depletion as a hallmark of the earliest Triassic interval globally. © The Author(s) 2016.},

Each specimen is represented solely by vegetative organs. On the basis of the material collected, a new algal genus and species has been formally erected. Vittella dixii nov. gen., nov. sp. (Order ?Bryopsidales) includes thalli consisting of long bundles of hair-like filament structures arranged in parallel fashion to the thallus length. Some other algal remains are regarded as Inocaulis-like forms. They possess long, flat blades with entire margins, and are ornamented with very dense, hair-like projections. The rest of the specimens found so far has been illustrated and tentatively classified as probably belonging to either Bryopsidales or Dasycladales algae. The exceptional preservation of the non-calcified algal thalli investigated suggests that special taphonomic conditions have prevailed during sedimentation of the lower part of the Famennian Kowala section. These may have involved rather rapid burial in oxygen-restricted (dysoxic and anoxic) sea-bottom environment, inhibiting the activities of scavengers and bioturbators, as well as oxidative degradation. The preservation of the algae, together with sedimentological and geochemical characteristics of the host rocks indicate that they rather represent parautochthonous assemblage, buried close to their natural habitat. © 2016 Elsevier Masson SAS.},

Two small (5 mm and 6.7 mm in length) tubes are composed entirely of tentaculitid shells, and one large tube (55 mm in length) is formed from particles including ostracode carapaces, echinoderm ossicles, tentaculitid shells and putative bryozoan fragments aligned perpendicularly to the tube's long axis. The tubes, in particular the large one have a cylindrical, curved and tapering tube morphology that is very similar to that of modern agglutinating polychaetes of the families Terebellidae and Pectinariidae. The large tube is dominated by objects that fall within a certain size-range, and although built from different types of particles, echinoderm ossicles are prevalent in the posterior part, whereas ostracode carapaces dominate in the middle and anterior parts of the tube. Tentaculitid shells are relatively rare in the large tube, despite being abundant in the surrounding host deposit. The faunal assemblage composing the tube suggests that the worm animal was rather specific in its selection of particles with a certain morphology. This is common behaviour amongst many modern agglutinating terebellid and pectinariid polychaetes. The preservation of such fragile tubes was enhanced by rapid burial, likely caused by gravity flow of sediment in a deep-slope setting. © 2015 Elsevier B.V.},

abstract = {Caddisflies (Trichoptera) are small, cosmopolitan insects closely related to the Lepidoptera (moths and butterflies). Most caddisflies construct protective cases during their larval development. Although the earliest recognisable caddisflies date back to the early Mesozoic (Early and Middle Triassic), being particularly numerous and diverse during the Late Jurassic and Early Cretaceous, the first records of their larval case constructions are known exclusively from much younger, Early to Middle Jurassic non-marine deposits in the northern hemisphere. Here we present fossils from the Early Permian (Asselian-Sakmarian) marine deposits of Brazil which have strong morphological and compositional similarity to larval cases of caddisflies. If they are, which is very probable, these finds not only push back the fossil record of true caddisflies, but also indicate that their larvae constructed cases at the very beginning of their evolution in marine environments. Since modern caddisflies that construct larval cases in marine environments are only known from eastern Australia and New Zealand, we suggest that this marine ecology may have first evolved in western Gondwana during the Early Permian and later spread across southern Pangea.},

The new species is not only one of the oldest representatives of true crabs, but also the most numerous in the world in terms of collected individuals (46 carapaces; including incomplete specimens) of the Middle Jurassic homolodromioid crabs. Tanidromites muelleri sp. Nov.. lived in a shallow-water, soft-bottom marine environment around developing oyster patch-reefs, being similar as later during the Late Jurassic when they lived in association with extensive sponge bioherms and coral reefs. The preservation of carapaces of the new species was influenced by a quick burial and rapid mineralization of calcitic concretions in which they are embedded. The stratigraphic distribution, to ammonite subzone level, of homolodromioid Middle Jurassic crabs is reviewed. Analysis of their paleoenvironmental preferences indicated that during the first step in the origin of true crabs they were connected with shallow, marine, high-energy carbonate deposits dominated by oolitic (including ferrugineus-oolitic one) facies, coralliferous reefs, and grey/black clays with carbonate concretions which hosted these crabs. © 2016 Copyright 2016 by The Crustacean Society.

Here, a new microconchid tubeworm species, Palaeoconchus wilsoni, is described from the Silurian (Ludlow) encrusting rugose corals from Estonia (Saaremaa Island) and a brachiopod shell from Sweden (Gotland). In Estonia, the microconchids are a dominant constituent of the encrusting assemblages, associated with cornulitids, Anticalyptraea, auloporids, trepostome bryozoans, hederelloids and enigmatic ascodictyids. It is notable that these Silurian encrusting assemblages are clearly dominated by tentaculitoids (microconchids; cornulitids and Anticalyptraea) which very often co-exist on the same coral host. Morphologically similar microconchids and Anticalyptraea may have exploited a more similar ecological niche than the straight-shelled cornulitids. However, the clear predominance of microconchids over Anticalyptraea in the communities may indicate that this genus was a less effective competitor for food than microconchid tubeworms. © 2016 Authors.},

Also their idea that microconchids, as supposedly strictly marine organisms, were preserved in nonmarine settings only because of transport by storm surges and tsunamis is unsupported on paleontological grounds.

abstract = {Soft tissue preservation is reported from Upper Devonian deposits of the Holy Cross Mountains, central Poland, for the first time. The preserved soft tissues are muscles associated with arthropod cuticle fragments. The muscles are phosphatized with variable states of preservation. Well-preserved specimens display the typical banding of striated muscles. Other muscle fragments are highly degraded and/or recrystallized such that their microstructure is barely visible. The phosphatized muscles and associated cuticle are fragmented, occur in patches and some are scattered on the bedding plane. Due to the state of preservation and the lack of diagnostic features, the cuticle identification is problematic; however, it may have belonged to a phyllocarid crustacean. Taphonomic features of the remains indicate that they do not represent fossilized fecal matter (coprolite) but may represent a regurgitate, but the hypothesis is difficult to test. Most probably they represent the leftover remains after arthropod or fish scavenging. The present study shows that soft tissues, which even earlier were manipulated by scavenger, may be preserved if only special microenvironmental conditions within and around the animal remains are established. © 2015 Zatoń, Broda.

Analysis of 225 specimens reveals that 71% of carapaces consist of complete/nearly complete specimens, and those that are incomplete have experienced purely taphonomic processes. The remaining 29% of specimens, are damaged and fragmented carapaces, the preservation patterns of which point to biological modifications due to predation. These damaged carapaces range from those that have some portions missing, to those totally fragmented into small pieces scattered on bedding planes. The damaged specimens lacking some portions of the carapace are similar to those described previously from the Frasnian of Australia, where they are interpreted to evidence fish predation. The loosely scattered cuticle fragments are very similar to those reported from the Pennsylvanian of the USA that are interpreted as shark regurgitates. We interpret the damaged and fragmented thylacocephalans from Poland as evidence for fish predation, consistent with previous evidence from fragmented cuticle preserved within coprolites. However, as the majority of cuticle fragments occurring within coprolites in previous studies are difficult to distinguish, the simple calculation of predation intensity is much lower (13%) to that obtained in the present study (29%). Thus, analysis of thylacocephalan carapace preservation conducted here, may serve as a calibrating tool for the assessment of a general predation intensity in a given palaeoenvironment based solely on coprolite data. © 2015 The Geologists' Association.},

abstract = {Vertebrate coprolites derived from Upper Triassic terrestrial deposits of southern Poland have been subjected to various analytical methods in order to retrieve information about their composition, producer's diet and nature of the microscopic structures preserved in the groundmass. Morphologically, the coprolites have been classified into four morphotypes, of which only three were further analysed due to their good state of preservation. Their groundmass are composed of francolite, a carbonate-rich apatite, in which abundant coccoid structures are preserved. Based on various microscopic and organic geochemical techniques, they are interpreted as fossilized bacteria which could have mediated the phosphatization of the faeces. The thin sectioning revealed that the coprolites consist of those containing exclusively bone remains, and those preserving both bone and plant remains. Those coprolites preserving only vertebrate remains are suggestive for exclusive carnivorous diet of the producers. However, the interpretation of coprolites consisting of both vertebrate and plant remains is more debatable. Although they may attest to omnivory, it cannot be excluded that potential producers were carnivorous and occasionally ingested plants, or accidentally swallowed plant material during feeding. The latter may involve predation or scavenging upon other herbivorous animals. The potential producers may have been animals that foraged in or near aquatic habitats, such as semi-aquatic archosaurs and/or temnospondyls. This is supported by the presence of ostracode and other aquatic arthropod remains, and fish scales within the coprolites, as well as by the presence of specific biomarkers such as phytanic and pristanic acids, which are characteristic constituents of fish oil. The preservation of such labile organic compounds as sterols, palmitin, stearin or levoglucosan attests for rapid, microbially-mediated mineralization of the faeces at very early stages of diagenesis. © 2015 Elsevier B.V.},

abstract = {Exceptionally preserved, phosphatized gastropod egg capsules from the uppermost Jurassic (upper Volgian) in Central Russia are reported. The egg capsules were attached to the inner side of the shell wall of empty body chambers of two ammonites. Due to phosphatization, the egg capsules retained their original morphology preserving both the lower attachment base and upper hemispherical cover. Comparison with recent and fossil gastropod egg capsules indicates that these were not produced by neritimorphs, the egg capsules of which are known from the Lower Jurassic and Upper Cretaceous. Since these fossil egg capsules share many similarities with those produced by some recent rissoids and muricid neogastropods, it is evident that they were produced by some representatives of Caenogastropoda. The abundant filamentous microbial structures, as well as micron-sized apatite globules, preserved inside the egg capsules suggest that phosphatization processes were mediated by microbial consortia under anaerobic and low-pH conditions. © 2015 SEPM (Society for Sedimentary Geology).},

abstract = {The upper Frasnian coral biostrome, well-exposed in the Russkiy Brod quarry, Central Devonian Field, Russia, has been studied in detail with respect to paleoecology and sedimentary environment. The biostrome, formed by auloporid tabulates and solitary and colonial rugose corals, originated in an offshore environment characterized by calmer periods with slow or halted sedimentation, and more energetic periods when sedimentation rate increased. The episodic, higher sediment influx and stronger hydrodynamic regime are not only well-expressed in the microfacies, but also in the variability of colony integration of the rugose corals observed even within single coralla. Distinct development of constrictions, rejuvenescences and deflection of growth directions in rugose corallites may also indicate unstable sedimentary conditions. The latter features, however, may have, in part, also resulted from syn vivo biotic interaction with the associated auloporids. Both the facies and paleontological observations suggest that the biostrome originated by the colonization of deposited bioclasts by pioneering auloporids, creating the framework for settlement of later generations of auloporids and rugose corals. Apart from abundant auloporids representing a single species and associated rugose corals, the other encrusters are not numerous and poorly diversified, represented by dominating foraminifers, followed by single species of productid brachiopods, stromatoporoids, microconchids and cornulitids. The coral-associated macrobenthos has similarly a low diversity, being represented by single species of spiriferid and rhynchonellid brachiopods, and gastropods. Being developed in an offshore carbonate sedimentary system devoid of any organic-rich deposits, and characterized by extremely low abundance and diversity of suspension-feeding organisms, the biostrome is considered to have originated in a low productivity, oligotrophic environment strictly dominated by heterozoan coral communities. Its development in a well-oxygenated, oligotrophic environment during the time when organic-rich, black Kellwasser facies developed elsewhere, additionally attests for multi-causal scenarios for the Frasnian-Famennian event, during which other factors were responsible in different paleogeographic and facies settings. © 2015 Elsevier B.V.},

abstract = {Carbonate cobbles from the lower Famennian (crepida conodont Zone) brachiopod shell beds of the Russkiy Brod Quarry (Central Devonian Field; Russia) have been investigated with respect to paleoecology and paleoenvironment. The cobbles, composed of similar shell bioclasts as the host deposits, were eroded from lithified shell beds during intervals of non-deposition. The smooth surfaces and the presence of borings and encrustations on all sides suggest that the cobbles were periodically transported and overturned.The fact that all the bioerosion traces are encrusted and none of the encrusters were bioeroded indicates that the first colonizers of the cobbles were worm-like suspension feeders, leaving long, cylindrical borings (Trypanites). The encrusting organisms are dominated by spirally-coiled microconchid tubeworms, followed by cornulitids, productid brachiopods, hederelloids, foraminifera, enigmatic Ascodictyon and trepostome bryozoans.The high abundance but low-diversity brachiopod fauna and general rarity of such stenohaline taxa as echinoderms in the shell beds or bryozoans on the cobbles suggest that the salinity fluctuated. The presence of dolomite crystals in both the host deposit and cobbles suggests that salinity increased from normal-marine to a higher salinity level during colonization of the cobbles. In fact, as shown by the facies and palynofacies data, the cobble-bearing deposits represent near-shore, restricted environments created during the first phases of transgression of the early Famennian that followed the regional regression at the Frasnian-Famennian transition. In such shallow, restricted settings a higher salinity could have appeared seasonally during a hot and dry climate.As with the microconchids from the aftermath of the end-Permian mass extinction, those from the post-crisis early Famennian interval of Russia were also dominant due to unstable environmental conditions. Here, at least in the case of the Russkiy Brod, the periodic higher salinity episodes may have discouraged other encrusters and thus promoted the settlement of the opportunistic microconchids. © 2014 Elsevier B.V.},

Their compact, pellet-shaped morphology and the presence of various fossil fragments scattered within the phosphatic groundmass clearly indicate that they are coprolites. The coprolite inclusions are dominated by arthropod cuticle fragments followed by fish remains, one conodont, and one scolecodont. The arthropod cuticle fragments are represented by the crustacean-like thylacocephalan Concavicaris and three other different types of arthropods of uncertain affinity. The presence of some conical fragments resembling telsons from phyllocarid crustaceans suggests that some of the cuticle fragments may belong to that group of arthropods. The fish remains mainly consist of actinopterygian paleoniscoid scales and sarcopterygian teeth. Taking both fossil and facies characteristics into account, it is clear that the coprolites originated from a carnivorous pelagic fishes that hunted other fishes and swimming arthropods. Surprisingly, similar faunal contents consisting of paleoniscoid fishes, Concavicaris arthropods, and conodonts occur in situ within the body cavities of the Famennian cladoselachian sharks in the Cleveland Shale, Ohio. Such a coincidence suggests that at least some of the Famennian coprolites from Poland may have also been produced by pelagic carnivorous sharks. The preservation of defecated remains was influenced by an interplay between an oxygen-deficient benthic environment devoid of bioturbators and scavengers and rapid, microbially-driven phosphatization. © 2013 Elsevier B.V.},

abstract = {Chitin occurs in a variety of invertebrates, especially in arthropod cuticles, but is rarely reported in the fossil record. Although it has been detected in fossils as old as Middle Cambrian and Silurian, the majority of records come from much younger, Cenozoic deposits. In this paper, we report the preservation of chitin in Early Jurassic neritimorph gastropod egg capsules deposited in bivalve shells from prodelta-deltafront and nearshore paleoenvironments of the Holy Cross Mountains, Poland. We used a number of analytical methods to confirm the presence of chitin preserved in these ancient fossils. This is the first record of chitin preservation in Mesozoic deposits that, interestingly, do not follow the conventional Konservat-Lagerst ätten manner of preserving soft-bodied and nonbiomineralized organisms. We believe that deltaic settings characterized by episodic, high input of fluvial deposits, oligohaline conditions, and oxygen-poor microenvironment within the sediment-as well as early cementation of sediment infilling the shells-were crucial for chitin preservation. The preservation of chitin in such recalcitrant structures as egg capsules and deposits that formed outside conventional Konservat-Lagerstätten conditions renders it likely similar deposits may yield promise for discoveries of similar biological macromolecules. © 2014 The Paleontological Society.

abstract = {In the present paper, the commonly mentioned but poorly recognised microconchid species Microconchus valvatus (Münster in Goldfuss; 1831) is redescribed on the basis of material from the Upper Muschelkalk of Germany. ESEM studies of the microconchid tubes with clear morphological and microstructural characters were compared to the existing known Triassic species. Microconchus valvatus is characterised by fine growth lines and transverse riblets. ESEM analysis shows that tubes which appear smooth under the binocular microscope are in fact abraded. Thus, taphonomy must be taken into account and scanning microscopy must be used during studies of microconchid tubes. Quantitative ecology shows that particular microconchid populations developed various size ranges punctuated by some gaps, have non-normal distributions as expected in time-averaged assemblages, and suggests that differences among populations may reflect distinct hydrologic settings. This study provides a multidimensional investigation of microconchids and offers compelling evidence that microconchids were an important faunal group during the post-recovery Middle Triassic interval. © 2013 The Author(s).},

abstract = {Microconchids have been described from the classic Pennsylvanian locality at Joggins, Nova Scotia. These encrusting tentaculitoid tubeworms have previously been mentioned and described from Joggins under the polychaete genus Spirorbis. Detailed morphological and microstructural investigation revealed that they belong to the species Microconchus carbonarius Murchison, confirming the previous tentative assignment (as Spirorbis carbonarius) made by Sir J. William Dawson in the nineteenth century. The occurrence of the same species in Upper Carboniferous deposits of England provides evidence supporting a connection between England and Nova Scotia in the Late Carboniferous (Pennsylvanian). Migration of the species could have been possible via brackish seas connecting both areas during maximum sea level during the Pennsylvanian. The species inhabited retrograding poorly drained coastal plain and open-water brackish environments, encrusting bivalve shells and plant remains in both sandstone and limestone deposits. Their high density (up to 19 individuals/cm2) may have resulted from their aggregative behaviour, high fecundity, and a lack of any competition with other skeleton-bearing encrusters. The large number (34%) of regenerated tubes indicates that microconchids were often preyed upon by associated animals, most probably fishes, which could graze on their dense encrusting aggregations.},

The phrase Kowala Lagerstätte is herein proposed for the fossil-bearing deposits confined to the lower Famennian marly shale and limestone succession of the famous Kowala Quarry. The arthropod fauna is represented by phosphatic exoskeletal remains that still preserve the fine micro-ornamentation of the cuticle. The fauna includes crustaceans and crustacean-like taxa such as thylacocephalans, phyllocarids and angustidontids (in order of abundance). The non-biomineralized algae, represented by at least three morphotypes, occur as carbonaceous compressions of their thalli while still preserving fine details including bundles of thin tubular projections. Although their general appearance is reminiscent of some Early Palaeozoic non-calcified Dasycladales algae, their true taxonomic position is still uncertain. Lithology, as well as faunal and phytoplankton content point to a pelagic sedimentary environment. Impoverished benthic fauna, sediment lamination and geochemical signatures indicate at least periodic bottom-water dysoxic to anoxic conditions. Thus, the preservation of arthropod cuticle and non-calcified algae was primarily governed by oxygen-deficient bottom waters that prevented bioturbation and scavenging during their burial. © 2014 Lethaia Foundation.

abstract = {A new species of a non-marine microconchid (Tentaculita) tubeworm, Microconchus hintonensis, from the Lower Carboniferous (Upper Mississippian; Chesterian) of West Virginia, USA, is described. Non-marine microconchids occur abundantly in the deposits of the Bluefield, lower Hinton, Princeton and Bluestone Formations of the Mauch Chunk Group, where they are either associated with land plant remains and bivalve shells, or are preserved loose in the host sediment. The specimens attached to plant remains and bivalve shells, are poorly preserved, but those occurring loose in the deposits are well-preserved in three dimensions. The interpretation presented here, is that the loose specimens of Microconchus hintonensis sp. nov. also originally encrusted plants (land plants; algae) and bivalve shells, but became detached after substrate degradation and dissolution. The association of land plant remains, charophyte gyrogonites, bivalves, ostracodes, conchostracans, and fish teeth and scales, and the concomitant lack of strictly marine fossils indicate that the microconchid-bearing deposits of the lower Hinton, Princeton and Bluestone Formations were deposited in fresh-water environments. Microconchus hintonensis sp. nov. is regarded as a highly fecund, opportunistic species that in large numbers colonized every available substrate in its habitat. Its abundance in the deposits investigated indicates that the species was welladapted to the environments it occupied, even during episodes of higher sedimentation rates and/or competition with other soft-bodied encrusters. During such episodes, microconchids were able to grow vertically by uncoiling and elevating their tubes, in order to escape potential burial and/or overgrowth by other encrusters.},

Typical Kellwasser facies of bituminous limestones and shales are not obviously recorded in shallow-water settings, and thus, it is unclear whether anoxia played a role in reef losses. We evaluate geochemical, petrographic and facies evidence for oxygen restriction from an extremely shallow-water carbonate platform in Alberta. Sequence stratigraphy places the Frasnian-Famennian boundary at a sequence boundary that tops a laminated mudstone and interrupts carbonate platform deposition. Two transgressive pulses have been identified, one of which is associated with the second, major transgression of T-R cycle IId of the Devonian eustatic sea-level curve. Geochemical proxies indicate that these transgressions were accompanied by influx of dysoxic or anoxic waters. Organic carbon and U enrichment in the Frasnian, particularly just below the Frasnian-Famennian boundary, points to episodic dysoxic conditions that probably persisted into the basal Famennian and were coincidental with the global Upper Kellwasser Event. This study provides the first evidence for the smoking gun of an anoxia-driven extinction in very shallow waters, implicating this potent killer in the demise of the Devonian reefs. © 2013 The Lethaia Foundation.},

abstract = {A study of patterns of episkeletobiont encrustation on the shells of two early Famennian brachiopods, Cyrtospirifer zadonicus and Ripidiorhynchus huotinus from Russia, revealed assemblages comprising seven skeletonised encruster taxa. The assemblages are dominated by spirorbiform microconchids, followed by cornulitids. Features such as shell malformations, frequent encruster growth towards the commissure of the shells, and encruster distribution in the areas adjacent to zones of possible water intake by the brachiopods indicate that these may have been colonised syn vivo. The lack of differences in encruster abundance between the two valves in C. zadonicus indicates that this species may have lived with both valves inclined at a high angle to the substrate. The significantly higher abundance of episkeletobionts on the brachial valves of R. huotinus may indicate that shells of this species were oriented with the brachial valve at a lower angle to the substrate, providing sheltered sites for coelobiotic larvae. Compared with pre-Famennian brachiopod-hosted encruster communities, this early Famennian community is impoverished in species richness and is dominated by microconchids. It is proposed that the epibionts witnessed a regression-related Frasnian-Famennian extinction event. During the recovery interval, opportunistic microconchids may have been among the first encrusters to colonise the pioneering brachiopods. © 2013 Taylor & Francis.},

abstract = {This study focuses on sclerobionts from a large collection of epibenthic echinoids (>2;000 specimens) of the genera Conulus and Camerogalerus. Samples were collected from five localities in southern Poland (Polish Jura and Miechów Trough), where Turonian carbonates with terrigenous input are exposed. Low intensity (mean ca. 5 %; maximum ca. 10 %) and slight encrustation ("loosening effect") exclusively by episkeletozoans probably resulted from low productivity of encrusters while the importance of other factors cannot be excluded unambiguously. Echinoids served as a main substratum and after death formed shellgrounds ('echinoid carpet') offering abundant benthic islands for encrusters in an otherwise soft-bottom environment. The moderate abundance but low-diversity assemblage is represented by bivalves, sedentary polychaetes, foraminifera, bryozoans, corals, and sponges. This assemblage is similar to a nearly contemporaneous assemblage from the Bohemian Basin. The presence of numerous spirorbins offers insights into their early evolution and may indicate that their first peak in abundance after origination was not prior to the earliest Turonian. This is regarded as one of the important ecological steps towards the rise of modern sclerobiont communities. Encruster diversities are independent of their abundance and, as shown in our novel planar projections, lateral parts of tests were preferentially encrusted. This pattern is explained by the combination of largest flat area and stable orientation. Encrusting bivalves and serpulids dominated hard substrate environments in the Turonian of Poland. © 2012 The Author(s).},

abstract = {Oystermicrobial rolling stones (ostreoliths) from the Upper Jurassic (Kimmeridgian) of Sulejo w and Malogoszcz, Poland, are described and interpreted in terms of their origin and development. The ostreoliths are composed mainly of small-sized oysters (Nanogyra nana) that initially encrusted bivalve or ammonite shells. These structures were frequently overturned during their further growth by hydrodynamic agents. The oyster shells are covered by a thin crust that is suggestive in appearance of a microbial mat. We postulate that the mats not only bound the shells, but also induced early cementation of the sediment infill, thereby triggering the rapid lithification and rigidity of ostreoliths. This interpretation is supported by the presence of bivalve borings that cut the shells, microbial crust and internal sediment infill. The oyster microbial association provided favorable conditions under which hardground biota thrived in a soft-bottom setting which was otherwise inimical to such organisms. These hardground biota are represented by a variety of encrusters (foraminifera and foraminifera-like problematica; plicatulid bivalves; cyclostome bryozoans; serpulids; and thecideid brachiopods) and borers (bivalves; bryozoans; and phoronids). Ostreoliths from Sulejo w are of smaller size, and with a less-developed oyster cortex, than those from Malogoszcz. This may be due to a higher frequency of physical disturbance (storms) at Sulejo w which halted ostreolith development at earlier phases than at Malogoszcz. A large oyster buildup recorded previously from Brzegi, close to Malogoszcz, suggests that, under favorable conditions, ostreoliths could eventually have transformed into stationary, patchreef type structures.

abstract = {Oncoids from two localities (Ogrodzieniec and Blanowice) of the Polish Jura, southern Poland, have been investigated with respect to their genesis and paleoecology. These oncoids occur within Middle Jurassic (Bathonian) deposits. Those from Ogrodzieniec are large, elliptical, and embedded within a presumably condensed carbonate bed. Those from Blanowice, on the contrary, are significantly smaller, irregular to box-like in shape, and occur within the ore-bearing clays. The oncoids from both localities consist of a distinct carbonate core and laminated cortex that is significantly thicker and better preserved in the Ogrodzieniec oncoids. SEM and optical microscopic investigation of the oncoid cortices revealed the presence of carbonate and silicate layers with web-like structures similar to those occurring in recent cyanobacterial microbialites. Thus, the oncoid cortices investigated may have formed in a photic zone environment with the aid of coccoid and filamentous cyanobacteria. Oxic conditions prevailed during oncoid cortex formation within the siliciclastic setting, which is manifested by low total organic carbon content, high pristane/phytane (Pr/Ph) ratio, and significant predomination of the C 31 homohopanes. On the cortices' surfaces, as well as between particular laminae, various encrusting organisms have been found. The encrusters, dominated by serpulids and bryozoans, are cryptic species that inhabited the undersides and recesses of the oncoids. Their presence on both the upper and lower surfaces of the oncoids indicates that the oncoids were episodically overturned on the seafloor. The much better developed cortex lamination and much higher diversity and abundance of encrusters in the Ogrodzieniec oncoids may point to better trophic conditions prevailing in a shallower marine environment characterized by transparent waters, as opposed to a deeper siliciclastic environment with less transparent waters and probably worse trophic conditions prevailing during formation of the Blanowice oncoids. © 2011 The Author(s).},

Based on palynomorph evidence, the age of the samples studied is late Lochkovian, not older than the NM Oppel Miospore Zone, specifically the Si Lineage Zone. The presence of acritarchs and chitinozoans points to dominantly marine depositional conditions. However, a regressive environmental change to-ward more brackish conditions is indicated by a decrease in the taxonomic diversity of acritarchs in the topmost samples, the simultaneous disappearance of chitinozoans, and an increase in leiosphaerid frequency. Furthermore, evolution of limestone microfacies demonstrates a progressive transition from a shrinking marine basin toward a brackish, storm-af-fected muddy lagoon, manifested by recurrent profusion of impoverished, mostly opportunistic and euryhaline shelly benthos (nuculanid bivalves; leperditicopids and other ostracods; terebratulid brachiopods), chaetetid demosponges and diverse ichthyofauna. The association of plant (mainly nematophytes and some tracheids) and animal (eurypterid; ?scor-pion; and possibly other arthropod) remains points to the presence of nearby Early Devonian wetland vegetation, provid-ing food and shelter for various semi-aquatic and other terrestrial arthropods.

abstract = {Reworked concretions have been significant substrates for boring and encrusting organisms through the Phanerozoic. They provide large, relatively stable calcareous surfaces in systems where sedimentation is minimal. Diverse sclerobiont communities have inhabited reworked concretions since the Ordovician, so they have been important contributors to our understanding of the evolution of these ecological systems. Here, we describe reworked concretions from southern Israel where they are critical for interpreting the stratigraphy and paleoenvironment of an Upper Cretaceous sedimentary sequence. These cobblesized concretions (averaging roughly 1;000 cm3) are found at the base of the Menuha Formation (Santonian to lower Campanian; Mount Scopus Group) unconformably above the top of the Zihor Formation (Turonian-Coniacian; Judea Group) exposed in the Ramon region of the Negev Highlands. The concretions are almost entirely composed of micritic limestone, and many are exhumed, cemented burrow-fills apparently from 10-20 m of upper Zihor Formation strata removed by erosion. There are also a few cobbles of dolomitic limestone and rare vertebrate bone. The cobbles are moderately to heavily bored by bivalves (producing Gastrochaenolites) and worms (forming Trypanites), and a few have cemented oysters. They are densely arrayed in a single layer, often touching each other or only a few centimeters apart. The sclerobionts associated with the cobbles, along with their hydrodynamic arrangement, strongly suggest that these cobbles accumulated in very shallow water above normal wave base. Most of them (77%) are encrusted on their top surfaces only, indicating that they were bored in place and not later delivered to a deeper environment by submarine currents. The rest of the Menuha Formation above is a chalk with relatively few macrofossils (primarily shark teeth and oysters) and a few trace fossils (Planolites and Thalassinoides are the most common). These reworked cobbles show that the initial deposits of the Menuha Formation accumulated in very shallow water. This has important implications for the development of the Syrian Arc structures in this region, especially the Ramon Monocline. © Senckenberg Gesellschaft für Naturforschung and Springer 2012.},

abstract = {Presented for the first time in this paper are the results of a detailed multi-proxy investigation conducted on the Hangenberg Black Shale (HBS) from the Polish part of the Laurussian Shelf, which provide details about the environmental conditions in existence during deposition of the shale and the role played by anoxic conditions in the mass extinction events that occurred at the end of the Devonian times. Inorganic and organic redox indicators indicate that bottom water redox conditions changed periodically from being mainly anoxic/euxinic to oxic or being partially depleted in oxygen. U/Th values above 1.25, Ni/Co values above 7 and V/(V. +. Ni) values above 0.8 recorded from the lower part of the HBS all point to anoxic/euxinic conditions being present, as do high total organic carbon contents (TOC) above 10% and degree of pyritisation (DOP) values around 0.75%. However, the presence of benthic fauna over the lower part of the HBS attests to opportunistic colonisation of the seafloor during oxic episodes. Evidence for similar episodes has also been recognised over the middle part of the HBS, e.g., U/Th values below 1.25, Ni/Co values below 4, V/(V. +. Ni) values below 0.8, TOC values of 3% to 5.5% and DOP values of 0.4% to 0.75%, plus the common occurrence of benthic fauna. Anoxic conditions returned during the deposition of the upper part of the HSB, though they were not as well developed as when the lower part of the shale was laid down.Of interest is the presence of small pyrite framboids and isorenieratene biomarkers in all the analysed samples, which suggest that euxinic conditions persisted in the photic zone of the water column. A twenty centimetre thick layer of volcanogenic deposits (tuffites) is present in the middle part of the HBS, the geochemical characteristics of which are typical of ocean floor basalts. The occurrence of volcanogenic material below and within the HBS, together with an absence of calcium carbonate over its upper part, the presence of abundant tetrads just above the black shale and a drastic decrease in faunal frequency in the upper part of the HBS imply that volcanism may have caused oceanic acidification (or hypercapnia) that in turn potentially may have influenced the Hangenberg mass extinction event. © 2012 Elsevier B.V.},

abstract = {Intriguing fossils encrusting oncoids and exhumed carbonate concretions are described from the Middle Jurassic (Bathonian) of Poland. The fossils, up to a few millimeters in diameter and preserved in a form of calcium carbonate, are characterized by a tubular, elongate shape with the external surface covered with distinctive semicircular to oval concavities. These tubes do not match any known fossils and do not represent trace fossils sensu stricto. They are similar to serpulid and/or sabellid polychaetes with which they are associated. The latter, however, have calcitic tubes and none are known to possess the concave structures that characterize the tubular fossils. The shape of the concavities and the presence of a carbonate lining within them suggest that the tubular fossils were originally covered with ooids, a few of which are still preserved in the concavities. These Middle Jurassic fossils may represent the fossilized remnants of agglutinated tubes formed by polychaete worms. Their greatest abundances are noted on media bearing thick microbial crusts (oncoidal in nature) on which they often form dense aggregations. This may indicate that the tube-building worms selected such media not only because they provided a suitable hard surface for settlement, but also because they were a rich source of food in the form of both microbes (Cyanophyta) and other organic matter present in the microbial mats. The selectivity of only ooids for tube building makes them dissimilar to any known recent tube-building polychaetes and, thus, the Middle Jurassic representatives are nonactualistic with respect to particle selection for the tube formation. © 2012 SEPM (Society for Sedimentary Geology).},

abstract = {The Middle Devonian (Givetian) microconchid tubeworm species known as Spirorbis angulatus Hall, 1861 is redescribed here on the basis of a new collection from the Traverse Group of Michigan and Hamilton Group of Ohio and New York, U.S.A. Its general characteristics and ornamentation indicate it belongs to the genus Palaeoconchus Vinn, 2006. Because the original specimens on which the species was erected are lost, a neotype is here designated for a specimen from the same area (Erie County; New York) and stratigraphic interval (Hamilton Group; Givetian) as the original specimens described by Hall (1861). The new specimens of Palaeoconchus angulatus (Hall) show that the species is characterized by a spectrum of morphological variability, possibly ranging from a nearly smooth tube, though weakly ornamented, to one distinctly tuberculated on which thicker nodes and thin spines may occur together. Assemblages of microconchids from particular stratigraphic divisions are characterized by a dominance of small (up to 1.5 mm in diameter; probably juvenile) individuals, while larger individuals (>2 mm) are rare. This suggests that the populations may have experienced occasional mass mortalities. Although substrate (in this case brachiopod shells and rugosan coral thecae) overturning and an increase in sedimentation rate are possible factors, an episodic anoxia/dysoxia of the bottom waters seems likely as it is known that the host dark shales record such occasional oxygen deficiency. © 2012 The Paleontological Society.},

abstract = {Microconchids are an extinct group of Spirorbis-like tentaculitoid tubeworms that dwelled in a variety of aquatic environments, ranging from normal marine, through brackish and hypersaline, to freshwater. An analysis of published microconchid occurrences focusing on their ecology and palaeoenvironmental distribution through geological time is conducted in order to establish the timing of microconchid colonization of freshwater and marginal marine habitats. Microconchids originated during the Late Ordovician in shallow shelf, normal marine environments where they thrived until their extinction at the end of the Middle Jurassic (latest Bathonian). Microconchid colonization of marginal marine brackish habitats seems to have started already by the Early Silurian (Wenlock). The freshwater habitats were invaded by microconchids in the Early Devonian, nearly simultaneously in several regions (Germany; Spitsbergen; USA). Since shallow marginal marine and freshwater habitats are more unstable, especially in terms of temperature and salinity fluctuations, as well as prone to desiccation, than normal marine, shelf environments, the drivers of the colonization of these habitats by microconchids are currently incompletely understood. We hypothesize that by colonizing such environments, microconchids gained access to abundant food resources in the form of suspended organic matter delivered from the land by rivers and streams. These, combined with their biology, enabled microconchids to reproduce fast and in large numbers. Microconchids are considered to have gone extinct by the end of the Middle Jurassic (Late Bathonian). Their youngest occurrence in freshwater environments is known from the Late Triassic and it is currently not known whether microconchids continued to occupy such habitats later on in the Jurassic. All the Middle Jurassic records of microconchids come from marine settings. Thus, more focused research on Jurassic brackish and freshwater deposits worldwide is needed to check whether they may have thrived in such environments at some locations, until their hypothesized extinction. © 2012 Elsevier Masson SAS.},

Its biological affinities have not been fully resolved and phylogenetic links with both annelids and cnidarians have traditionally been suggested. Differences in tube morphology, ultra structure and biomineralization suggest that Cloudina is not closely related to any recent skeletal annelid (e.g.; serpulids; sabellids and cirratulids) and their skeletons are not homologous. The way of asexual reproduction in Cloudina resembles more that of cnidarians. The presence of a closed tube origin (base) in Cloudina is also compatible with the hypothesis of an animal of cnidarian grade.},

Most of the plant and animal remains are palynologically dated as Pragian-Emsian/Eifelian. The plant material comprises higher plant cuticles with stomata classified as Drephanophycus and Sawdonia, and more enigmatic remains (nematophytes) classified as Nematothallus, Cosmochlaina and tubular banded tubes. They are associated with abundant and diverse miospores. Animal remains consist of eurypterid respiratory organs, the morphology of which may presumably point to their advance physiological properties, and cuticular remains of eurypterid and probably scorpion origin, as well as some remains of unknown affinity. The presence of such mixed assemblages in the Lower Devonian of Poland indicate marginal-marine and/or alluvial environments spreading in the southern margin of the Old Red Continent. The dominance of land-derived plant remains and simultaneous scarcity of marine acritarchs indicate that the environment was very weakly influenced by marine conditions. If nematophytes were really related to extant liverworts, as suggested by some workers, they, together with the other associated spore-producing plants, may strongly indicate moist environmental conditions, which may have offered suitable habitats for temporary eurypterid migrations onto land. □ Cuticles, eurypterids, Lower Devonian, nematophytes, Poland, spores. © 2010 The Authors, Lethaia © 2010 The Lethaia Foundation.},

abstract = {Microconchids are a group of tiny, encrusting tubeworms. They appeared in the Late Ordovician, some 450 Myr ago, flourished during the rest of Palaeozoic and Triassic, and became extinct in the Middle Jurassic. Their morphological resemblance to the sedentary polychaete genus Spirorbis, very common in marine environments, misled various authors for decades. This mistake originally gave the genus Spirorbis an enormous stratigraphical range, from Ordovician to Recent. Indeed, microconchids provide an excellent example of evolutionary convergence with respect to both their morphology and ecology. In the late 1970s these 'spirorbids' were interpreted as vermetid gastropods on the basis of the inner architecture and microstructure of their tubes. This idea, however, was challenged in the 1990s when detailed microstructural investigation showed them to be neither polychaetes nor gastropods, but closely related to an extinct Palaeozoic enigmatic group of organisms called tentaculitids. No thorough investigation of their origin, phylogeny and ecology has ever been conducted, but new data concerning their palaeobiology has come to the light during the last few years. © 2011 Blackwell Publishing Ltd, The Geologists' Association & The Geological Society of London.},

The condition of microconchids and associated encrusting taxa is reported for the first time from the early Famennian recovery interval (crepida Chron) following the Frasnian-Famennian mass extinction. Two species, one new (Palaeoconchus variabilis sp. nov.) and the second one in open nomenclature (Palaeoconchus sp.), are described. Compared to lower Famennian specimens, they seem to be preferentially grouped on the anterior parts of the brachiopod host shells, which are interpreted as the most suitable sites away from the sea-bottom and sediment. During the late Frasnian (Late rhenana Chron), microconchids, outnumbered by cornulitids and as abundant as foraminifers, were also associated with trepostome bryozoans, tabulates, rugose corals and various problematic encrusters. During the early Famennian recovery interval encompassing the crepida Chron, microconchids greatly outnumbered all associated encrusters, including the previously dominant cornulitids, while foraminifers, tabulates and rugose corals vanished. Early Famennian microconchids, represented by the single, albeit very abundant, species Palaeoconchus variabilis sp. nov., were opportunists that rapidly colonised the environment during the ongoing transgression following the regression-driven biotic crisis in the area of the Central Devonian Field. In comparison to their late Frasnian predecessors and even other Middle Devonian specimens, no size reduction (the so-called Lilliput effect) of early Famennian microconchid tubes was observed. It is probable that microconchids either rapidly attained their 'normal' sizes or they did not suffer any dwarfism following the Frasnian-Famennian event. © The Palaeontological Association.},

At least 27 encrusting and seven bioerosion taxa are reported here, which makes this assemblage not only one of the most diverse in the Middle Jurassic, but the richest in encrusting taxa from the Callovian. The encrusters consist of cryptic biota of which sedentary polychaetes and cyclostome bryozoans dominate with respect to both species number and abundance. The bioerosion traces are dominated by tiny pits referred to the ichnogenus Oichnus, probably made by some soft-bodied biota in the present case, followed by the borings of acrothoracican barnacles (Rogerella). The first colonizers of the bivalve shells probably were borers as they only occur in the host shells. The encrusting pioneers presumably were oysters and oyster-like bivalves, followed by opportunistic serpulid/sabellid polychaetes and cyclostome bryozoans. The last colonizers were calcisponges and thecideide brachiopods. In comparison to the only known Late Callovian shallow and reef-associated, tropical sclerozoans of Israel, the assemblage from the open-marine, deeper setting of Poland is much richer in encrusting taxa. Such a surprising high encruster diversity in the marine northern paleo-latitude may have resulted from the deeper and calmer environment with a both reduced sedimentation rate and algal cover, and without any significant salinity changes, the factors that are thought to have impacted the tropical and shallow-marine sclerozoans from Israel. © 2011 Elsevier B.V.},

The microconchids inhabited fully marine environments during transgressive pulses, as is evidenced from facies and associated fossils. Polonoconchus skalensis n. gen. n. sp. and Palaeoconchus sanctacrucensis n. sp. inhabited secondary firm- to hard-substrates in deeper-water, soft-bottom environments. They developed planispiral, completely substrate-cemented tubes and planispiral tubes with elevated apertures, which is indicative of environments where sedimentation rate is low but competition for space (by overgrowth) may be high. Microconchus vinni n. sp., on the other hand, developed a helically coiled distal portion of the tube as a response to a high sedimentation rate.

The data used in this study are based on a large number of ammonoid specimens, collected bed-by-bed, from the Polish Jura in south-central Poland, as well as on existing literature. The ammonoid diversities, both at the genus and species levels, have been calculated for particular ammonite zones and subzones and compared with the regional transgressive-regressive cycles for the Polish Lowlands and Hallam's global sea-level curve. The patterns of ammonoid diversity dynamics seem to be well correlated with global sea-level fluctuations. Particular diversity peaks correspond with major transgressive episodes. Three main regional bio-events related to transgressions have been distinguished for the Polish Basin: (1) the Latest Bajocian (Bomfordi Subchron) bio-event is related to a short-lasting immigration of Tethyan ammonoids; (2) a late Early Bathonian (Tenuiplicatus Chron) bio-event corresponds to a proliferation of Asphinctites tenuiplicatus (Brauns), most probably as a result of transgression-driven eutrophication of a shallow-marine environment; during this time, the immigration (passive dispersion?) of some single Tethyan species is also observed; and (3) a Late Bathonian (Hodsoni and Orbis chrons) bio-event corresponds to the highest ammonoid species diversity peaks and most probably is related to the major transgression during the Bathonian, which allowed easy migration of several species via several newly opened sea ways. © The Author(s) 2010.},

abstract = {Bored and encrusted carbonate concretions, termed hiatus concretions, coming from the Middle Jurassic (Upper Bajocian and Bathonian) siliciclastics of the Polish Jura, south-central Poland, have been subjected to detailed paleoecological investigation for the first time. The concretions possess variable morphology and bear distinct traces of bioerosion and encrustation as a result of exhumation on the sea floor during intervals of low sedimentation and/or erosion. The borings are dominated by Gastrochaenolites and Entobia. Epilithozoans, represented by at least 26 taxa, are dominated by sabellid/serpulid worm tubes and bryozoans, while sponges and corals are minor. No relationship between the concretion size and the number of encrusters has been found, suggesting that concretion size was not the primary factor controlling diversity. Stable isotope analyses and the presence of crustacean scratch marks and Rhizocorallium traces on many of the hiatus concretions indicate that they formed just below the sediment-water interface, within the sulfate reduction zone. Moreover, crustacean activities may have been a prelude to their origin, as shapes of many concretions closely resemble thalassinoidean burrow systems. It is also possible that crustacean activity around the concretions promoted their exhumation by loosening the surrounding soft sediment. The presence of borings and encrusters on different concretion surfaces, as well as truncated borings and a number of abraded epilithozoans, indicate that after the concretions were exhumed they were repeatedly overturned and moved on the sea floor, probably due to episodic storm-related bottom currents in shallow subtidal environment. © 2010 Springer-Verlag.},

abstract = {Wildfires play a crucial role in recent and ancient ecosystem modeling but their detailed history on the Earth is still not well recorded or understood. The co-occurrence of charcoal and pyrolytic polycyclic aromatic hydrocarbons (PAHs) is used for the recognition of wildfires in geological record that may have implications for the analysis of the terrestrial environment, ecosystems, climate and the level of atmospheric oxygen. Here we present the first multi-proxy evidence of wildfires on the Gondwana continent during the Jurassic, based on the occurrence of charcoal and pyrolytic PAHs in the Middle Jurassic of the Neuquén Basin, Argentina. This is the first evidence of wildfire in the Aalenian, the lowest stage of the Middle Jurassic, and one of the few records of wildfires in the Bathonian. Temperature interpretations, derived from charcoal reflectance data, show that charcoals formed in low temperature surface fires that only sporadically reached the higher temperatures, possibly related to crown fires. The occurrence of charcoals in the Middle Jurassic deposits confirms recent results that the atmospheric oxygen level reached at least 15% during the Middle Jurassic times. © 2010 Elsevier B.V.},

abstract = {This study presents the first organic geochemical and petrographical investigation of the Callovian deposits of the eastern part of the Central European Basin. It is shown that in both the terrigenous Papilė Formation (Lower Callovian) and shallow- to deeper-marine facies of the Papartinė and Skinija formations (Middle and Upper Callovian; respectively), terrestrial organic matter predominates. This is reflected by the carbon preference index values higher than 1.2 for all samples and in some cases higher than 2, as well as the occurrence of characteristic higher plant biomarkers like cadalene, dehydroabietane, simonellite and retene. Moreover, in the case of the Papilė Formation, sugiol - a natural product terpenoid produced by distinct conifer families, has been detected in clay sediments. The occurrence of such a biomolecule in the Middle Jurassic clays is reported for the first time. Its occurrence is probably connected with the presence of small wood debris in the clay sediments. In samples of the Papilė Formation, charcoal fragments co-occurring with unsubstituted polycyclic aromatic hydrocarbons were detected, indicating that wildfires took place during the Early Callovian of Lithuania and/or neighbouring areas. In the Middle and Upper marine Callovian sediments of Lithuania there is no evidence of anoxic conditions occurring in the water column. However, periodic anoxic or strongly dysoxic episodes may have occurred, most probably below the photic zone, during the deepest phase of the Late Callovian transgression, as is evidenced from pyrite framboid diameter distribution and general impoverishment of benthic fauna. Huminite reflectance (Rr) values for the investigated area are in the range of 0.21-0.31%, suggesting the occurrence of immature organic matter. Such values indicate that these investigated deposits were close to the surface during their whole diagenetic history, and the thickness of younger cover did not exceed ca. 500m. This is also supported by a biomarker analysis in which less thermally stable ββ-hopanes and hopenes significantly dominated. © 2010 Elsevier Ltd.},

abstract = {Sublethal injuries, the effects of which are seen as regeneration patterns, are described from Late Bajocian and Bathonian (Middle Jurassic) ammonites from Poland (Polish Jura area) for the first time. The total number of ammonite shells bearing signs of sublethal injuries is small (only 11 specimens; which constitute ∼1.2% of all ammonites investigated), and this value is even smaller (∼0.3 to 0.8%) when analysing a large sample of a particular ammonite species. Specimens under consideration represent ten species, belonging to six genera and five families. All the healed injuries are represented by only one type, referred to as the 'forma verticata' of Hölder. This type of regeneration, very common in ammonite shells in general, is an effect of a puncture injury of the shell-secreting mantle-epithelia at the apertural margin. Although many different extrinsic (mechanical) factors may be responsible for such healed injuries, here it is most plausible they are an effect of either competitive or predatory activities. Other causes, like collision of the ammonite shells with the substrate in a high-energy environment, are excluded because the sea-bottom was soft and situated below the storm wave-base. From many potential predators inhabiting the Polish Basin during the Bajocian and Bathonian, the most likely to have caused these injuries are other ammonites, belemnites and nautiloids. Crabs, which are cited in the literature as a probable perpetrator of the 'forma verticata' injuries, appear unlikely here, as the ammonites under discussion were not purely benthic. © 2010 Elsevier Masson SAS.},

abstract = {Integrated palynological, organic and inorganic geochemical and petrographical methods have been used for deciphering the depositional redox conditions and character of organic matter of the Famennian Dasberg event horizon from the deep-shelf Kowala succession of the Holy Cross Mountains. The ages of the investigated samples have been established, using miospore data, as VF (Diducites versabilis-Grandispora famenensis) and LV (Retispora lepidophyta-Apiculiretusispora verrucosa) miospore Zones of the Middle/Upper Famennian. In the standard conodont zonation, this corresponds to the uppermost postera to lowermost praesulcata Zones. The presence of green sulphur bacteria biomarkers and dominance of small-sized framboids together with the presence of large framboids and low values of the U/Th ratio may indicate that during sedimentation of the lower Dasberg shale, intermittent anoxia occurred in the water column, or the anoxic conditions prevailed in the upper part of the water column, while the bottom waters were oxygenated, at least briefly. Deposition of the upper Dasberg shale was characterized by both bottom water and water column anoxia. The lack of acritarcha taxa from these intervals could have been due to anoxia in the photic zone. Moreover, organic content is high in those samples. There is no geochemical evidence for anoxia during sedimentation of the deposits sandwiched between the lower and upper Dasberg shales, or in the deposits which underlie and overlie both Dasberg shale horizons. The two discrete anoxic events are interpreted to be the result of major transgressions and the blooming of primary producers. Above the Dasberg shales, small fragments of charcoal and raised concentrations of polycyclic aromatic hydrocarbons are detected. This supports the presence of wildfires during deposition of shales just above the boundary of VF/LV palynological zones. Temperatures calculated from the fusinite reflectance values suggest that the charcoal was formed in low-temperature ground and/or surface fires. The typical marine character of sedimentation combined with the high proportion of charcoals suggests that wildfires were large-scale, and that there was intensive transport of terrestrial material. The main causes of intensive wildfires were a significant rise of O2 in the atmosphere and important progress in the land plant diversity during Late Devonian times. Palynofacies studies suggest that the transgression corresponds to the part IIf of the Late Devonian sea-level curve. © Cambridge University Press 2010.},

abstract = {Fossil gastropod egg capsules have rarely been reported from the fossil record. This paper describes gastropod egg capsules preserved exclusively on cardiniid bivalves from Lower Jurassic (Hettangian) deltaic deposits of the Holy Cross Mountains area, central Poland. In most instances, only the bases of the egg capsules are preserved as dark outer rings with hollow cavities inside. Some specimens, however, are preserved as dark circular spots or even shallow depressions on the bivalve molds. The general occurrence, morphology, size and composition of the egg capsules as revealed by Energy Dispersive Spectroscopy (EDS) analyses and elemental mapping point to neritimorphs as the most probable producers. The egg capsules are composed primarily of organic matter with some calcium. Recent neritid gastropods possess aragonitic spherules within the egg capsule walls composed of conchiolin or chitin, which strengthen them and increase their chance of fossilization compared to egg capsules of other gastropods. Recent neritids lay their egg capsules on mollusk shells as well. The occurrence of Early Jurassic egg capsules only on redeposited cardiniid bivalve shells may suggest that the shells were the best medium for egg-capsule deposition. The occurrence of egg capsule bases together with dark circular spots, interpreted as compressed unhatched capsules, suggests that these egg capsules either hatched or were deposited at different times in the same place. The Early Jurassic egg capsules were preserved due to the strengthening role of the carbonate phase within the wall and rapid burial coupled with limited bioturbation in deltaic settings. The prodelta-delta front depositional environment, with high rates of sedimentation by rivers and sediment redistribution by wave and current action, was favorable for preserving these fossils. © 2009 SEPM (Society for Sedimentary Geology).},

The oldest representatives of cyrtocrinids were known from the Early Jurassic, therefore the presented material constitutes the oldest world record of these crinoids to date. We speculate that perturbations related to the global mid-Carnian extinction combined with predation intensity observed in the Middle- Late Triassic have been involved in early origin of Cyrtocrinida.},

Canu is deemed to have created a new nominal species, Oncousoecia lobulata Canu, 1918, which is the valid type species of Oncousoecia. Microeciella Taylor and Sequeiros, 1982 and Eurystrotos Hayward and Ryland, 1985 have each been used to accommodate similar oncousoeciid species with subcircular colonies. The type species of Eurystrotos, Alecto compacta Norman, 1867, has a branching colony-form and does not differ appreciably from Oncousoecia with which it is here synonymized. Another species, Diastopora suborbicularis Hincks, 1880, previously regarded as being a junior synonym of A. compacta Norman, 1867 (itself a subjective junior synonym of Alecto dilatans Johnston; 1847), has a different ancestrular morphology and an unbranched colony-form.

abstract = {Knowledge of early, Mesozoic crabs is still rudimentary, mainly due to the poor preservational potential of crustacean decapods. Fossil evidence suggests that the family Prosopidae is ancestral to all other brachyurans, including Podotremata, with a very close phylogenetic relationship to Homolodromiidae, Dromiidae, Homolidae, Latreillidae, Dynomenidae, Xanthidae, Cyclodorippoidea and Calappoidea. Prosopidae is an extinct family, consisting mostly of Mesozoic species, almost exclusively known by their carapaces. This family appeared in the late Early Jurassic (Late Pliensbachian) and disappeared at the end of the Danian. The Early Jurassic (Pliensbachian) oldest crab species, Eocarcinus praecursor Withers, is transitional in many of its observable traits between the macruran Glypheoidea (Middle Triassic Pseudopemphix) and the early brachyuran prosopids, especially the earliest known species, Eoprosopon klugi Förster (Late Pliensbachian). Middle Jurassic prosopids lived in shallow-sea, soft bottom environments. The oldest known prosopid species lived on a silty sea floor, as did the first known crab (late Early Pliensbachian), and their presumed ancestors (Pemphicidae) were probably also shallow water organisms. Middle Jurassic prosopids lived both in shallow warm waters within organic buildups/shelly accumulations, and on silty sea-floors during the Bajocian/Bathonian, as illustrated by a new example from central Poland. Prosopids had an evolutionary climax during the Late Jurassic and were widely distributed in sponge-microbial (Oxfordian) buildups and coral reef (Kimmeridgian-Tithonian) environments of Europe (Pithonoton; Coelopus; Longodromites; Prosopon; Nodoprosopon; Lecythocaris; Glaessneropsis). When biohermal and reef facies retreated at the end of the Jurassic, favourable conditions for prosopid crabs diminished and Cretaceous prosopids are rare and spatially dispersed. Their closely related descendants, the homolodromiids, preferentially inhabited soft muddy bottoms in deeper, colder waters, as is well documented by Cenozoic and Recent occurrences. © 2008 Elsevier B.V.

Levoglucosan is a general source-specific tracer for wood smoke in the atmosphere and recent sediments. The presence of unusually high levels of this compound in brown coal pyrolysates suggests that a portion of this compound concentration in some airsheds may originate from lignite combustion. On the other hand, nonglucose anhydrosaccharides, in particular, mannosan and galactosan, typical of hemicellulose, are not detected in those lignite pyrolysates investigated. This indicates that mannosan and galactosan are better specific tracers for combustion of contemporary biomass in those regions were the utilization of brown coals containing fossilized cellulose is important. © 2008 American Chemical Society.},

The characteristics of pyrite framboids, their origin and principles of application in paleoenvironmental interpretations are given. The pyrite framboid diameter distribution as indicators of redox conditions was presented on the examples of the Middle Jurassic (Upper Bajocian-Lower Bathonian) ore-bearing clays of the Polish Jura, and Upper Devonian (Middle and Upper Famennian) dark grey and black shales from Kowala (Holy Cross Mountains). It has been shown, that during the sedimentation of the ore-bearing clays, the pyrite framboids formed in the sediment, below the oxic water column; however, some episodic oscillation around the dysoxic conditions cannot be entirely excluded. During the sedimentation of the Middle Famennian dark grey shales, the redox conditions at the sea-floor oscillated around dysoxia. In both examples, the framboids are characterized by wide range of their diameters and the presence of large, > 10 μm, framboids. On the contrary, the Upper Famennian black shales, representing the Hangenberg event, were deposited below the euxinic conditions in the water column. It is indicated by a high frequency of small-size framboids, far below 6 μm in diameter, and the lack of the large ones. The overlying shales, on the other hand, show the transition to more oxic conditions. The redox conditions interpreted above are in agreement with the independent biomarker analyses and paleontological observations.},

abstract = {The taphonomy of three Middle Triassic (Muschelkalk) monospecific ophiuroid taphocoenoses, comprising Aspiduriella similis (Eck), from different regions in Poland (Holy Cross Mountains; Upper Silesia and North-Sudetic Basin) has been investigated. The majority of specimens (88.5% of a total of 428 individuals) are partially disarticulated, having only proximal and median portions of their arms preserved (Taphonomic Group 2). Pristine specimens, with only faint traces of disarticulation (Taphonomic Group 1), as well as those that preserve the disc only, or which have only proximal stumps of arms preserved (Taphonomic Group 3), are much rarer (6.5% and 5%; respectively). Moreover, most specimens (76.4%) are oral side up. Only 19.2% of specimens are preserved in life position, and a small fraction (4.4%) are preserved oblique to bedding. All ophiuroids studied occur in thin, pelitic layers devoid of any trace fossils. Associated body fossils, such as bivalves, gastropods or crinoids, are very rare. Taking into account ophiuroid taphonomy, as well as sedimentological characteristics of the thin layer (burial layer), it is clear that all assemblages were transported prior to burial. The predominance of articulated skeletons indicates that the burial event (obrution event) was not only rapid, but also single -subsequent events would have destroyed the previously buried ophiuroids. Storm-related resuspension of fine-grained material from nearshore environments which covered the ophiuroids is the most likely burial agent. The fact that in all regions the ophiuroid taphofacies studied is identical suggests that the three assemblages underwent the same burial history, and that a single event might have been responsible. © 2007 The Author, Journal compilation © 2007 The Lethaia Foundation.},

abstract = {Taxonomic revision of a number of species belonging to the Middle Bathonian tulitid genus Morrisiceras (Morrisiceras Buckman - macroconchs and Holzbergia Torrens - microconchs) from the Polish Jura (south-central Poland) and England, shows that the genus is in fact represented by one, albeit morphologically very plastic (especially macroconchs), species Morrisiceras morrisi (Oppel). In the Polish Jura area, all of the previously described morphotypes of the macroconch, along with its microconch Holzbergia, are characterized by their identical stratigraphic ranges, both being confined to the Middle Bathonian Morrisi Zone. Much smaller microconchs (males) may have attained maturity earlier than their macroconchs (females). Morphologically very plastic macroconchs seem to have attained full maturity at various shell diameters. Such phenomenon is known in recent coleoids and similarly may be the result of changing environmental conditions. Palaeobiogeographically, the main area occupied by the species was confined to the epicratonic seas, which spread across what is now present-day central and North-West Europe, with some occurrences in western Asia (Turkmenistan/Uzbekistan) and sporadic occurrence in a deep-water facies of Apulia (Italy). Taphonomical observations suggest that Morrisiceras shells have not undergone significant post-mortem drifting or transport after deposition. The preservation of some of the Morrisiceras morphotypes, occurring as dorso-ventrally flattened specimens in the host clays, may indicate that they were quickly buried in life position after they have landed on the sea-floor. © 2008 Elsevier Masson SAS.

abstract = {The Callovian (Middle Jurassic) fossiliferous carbonate concretions from the clay-pit at Luków, eastern Poland, have been analysed using organic geochemistry, petrography and pyrite framboid size distribution in order to retrieve information about early diagenetic conditions during clay sedimentation. Additionally, a fossil wood sample was also analysed. The carbonate concretions are formed almost entirely by fine-grained, pure calcite. Other main minerals occurring in the concretions are quartz, feldspars and bright mica with features of muscovite. The clay fraction obtained from the concretions are mainly composed of quartz, but also contains pyrite, muscovite, mid-order kaolinite and chlorite with an admixture of a mix-layered structure. Small admixtures of siderite, ankerite, rutile and feldspars were also detected. The most plausible source of the terrigenous phases occurring in the concretions investigated is the Fennoscandian Shield, where sodic magmatic and metamorphic rocks are common. In the fossil wood, the main mineral phase is calcite, which fills the wood-cells. Fluoroapatite also occurs, but is generally confined to the margins of the cells. The other phase detected is pyrite, which may also fill the cell interiors and replace the cell walls. The Callovian organic matter (OM) from Łuków is immature. The vitrinite reflectance (Rr) of the analysed concretion samples ranges from 0.45 to 0.54 %, and is higher than from the fossil wood (Rr = 0.33 %). Moreover, the concretion samples contain hopanoids with biological configurations, such as ββ-hopanes and hop-17(21)-enes and characterized by low values of ββ/(αβ + βα)-hopane and 31S/(S+R) homohopane biomarker parameters. The occurrence of acyclic ketones with odd over even carbon number predominance in the concretions studied, suggests intensive microbial degradation of OM. The pyrite framboid size distribution does not indicate euxinic or anoxic conditions in the water column and the sea-floor. Although small-sized framboids (< 5 μm), which may form during euxinic conditions in the water column, occur in all samples investigated, the mean sizes of framboids in all samples are well above 6 μm and large framboids (up to 29 μm) are also present. Their size distribution points to the lower dysoxic conditions at most, because during such conditions the mean values of framboid sizes begins to increase and larger framboids (> 10 μm) are present. The oxic to suboxic depositional conditions during OM sedimentation are also confirmed by low concentrations or absence of C33-C35 homohopanes, moderate Pr/Ph values and no organic compounds characteristic of anoxia and water column stratification. ©2008 E.

This work analyzes the organic geochemistry of particularly well preserved samples of Xenoxylon from the Callovian of Łuków (eastern Poland) for comparison with the Bathonian of Gnaszyn (south-central Poland). The wood fragments from both Łuków and Gnaszyn contain phenolic abietanes like ferruginol, 6,7-dehydroferruginol, sugiol, hinokiol or 2-ketototarol. The presence of such biomolecules, with simultaneous absence or very small amount of tetracyclic diterpanes such as phyllocladanes, beyerane and/or kauranes, is characteristic for extant conifer families Cupressaceae s. 1. and Podocarpaceae. Thus, the molecular composition of the wood genus Xenoxylon suggests systematic relationships with these extant families. This study presents the evidence that preserved biomarkers and biomolecules are not exceptional in fossil wood, and that their composition generally supports the anatomical data. ©2008 E.

In this paper, evidence of durophagous predation on Middle Jurassic communities of molluscan prey is presented on the basis of distinct accumulations of fossil remains in the Polish Jura (south-central Poland) that contain characteristic, angular shell fragments with sharp, non-abraded margins. The diverse fossil content of the accumulations studied, consisting of either benthic or nektic/nekto-benthic taxa, indicates that the potential predatory taxon was an opportunistic generalist, most probably fish. On the basis of taphonomic observations, the faunal accumulations are interpreted to represent regurgitated remains (pellets). The common occurrence of such accumulations in the Middle Jurassic clays of the Polish Jura indicates that durophagous predation has been intense since the mid-Mesozoic, at least locally. © 2008 The Palaeontological Association.},

abstract = {The comprehensive biomarker characteristics from previously undescribed Middle Jurassic clays of Poland are presented. The molecular composition of the organic matter (OM) derived from clays of Aalenian to Callovian age has not changed significantly through time. High relative concentrations of many biomarkers typical for terrestrial material suggest a distinct dominance of OM derived from land plants. Increasing concentrations of C29-diaster-13(17)-enes towards the northern part of the basin indicate an increase in terrestrial input. This terrestrial material would have originated from the enhanced transport of organic matter from land situated at the northern bank of the basin, i.e., the Fennoscandian Shield. The organic matter was deposited in an oxic to suboxic environment, as indicated by relatively low concentrations of C33-C35 homohopanes, moderate to high Pr/Ph ratio values, an absence of compounds characteristic for anoxia and water column stratification, such as isorenieratane, aryl isoprenoids and gammacerane, as well as common benthic fauna and burrows. δ18O measurements from calcitic rostra of belemnites suggest that the mean value of the Middle Jurassic sea-water temperature of the Polish Basin was 13.1 °C. It is suggested that this mirrored the temperature of the lower water column because belemnites are considered here to be necto-benthic. The organic matter from the Middle Jurassic basin of Poland is immature. This is clearly indicated by a large concentration of biomarkers with the biogenic configurations, such as ββ-hopanes, hop-13(18)-enes, hop-17(21)-enes, diasterenes and sterenes. The identification of preserved, unaltered biomolecules like ferruginol, 6,7-dehydroferruginol and sugiol in Protopodocarpoxylon wood samples from these sediments present particularly strong evidence for the presence of immature OM in the Middle Jurassic sediments. Moreover, the occurrence of these polar diterpenoids is important due to the fact that they are definitely the oldest known natural products detected in geological samples. © 2007 Elsevier Ltd.

abstract = {Distinct faunal accumulations in the uppermost Bajocian/lowermost Bathonian, lowermost and Middle Bathonian of the Polish Jura (south-central Poland) have been detected. The fossils are densely packed in the centre of the accumulations and more or less dispersed in their margins. The accumulations vary in size, but all are rich in various groups of organisms, of which the molluscs (mainly bivalves) and echinoderms predominate. The echinoderms are all disarticulated, and shelly fauna occur as angular fragments with sharp edges, of random sizes and without any signs of abrasion. The different sizes of the fossil remains, from tiny echinoderm ossicles or juvenile shelly fauna to medium-sized shell fragments or belemnite rostra, exclude any transportation and thus sorting. Worth of noting is the occurrence of similar faunal groups in each accumulation. The general shape and composition of the accumulations, as well as their taphonomical features, especially the angularity of shell fragments, point to durophagous (shell-crushing) predation rather than physical processes. The various organisms may indicate that the potential predator (most probably fish) fed on various invertebrates. The indigestible particles were later regurgitated forming the accumulations discussed. The presence of various epibionts on the fossil fragments indicate, that they rested upon the sea-floor for some time-span after they had been regurgitated. Then the scavengers, as well as current action or water movements, have been responsible for dispersion of some of the fossils, as is well-visible at the margins of the investigated accumulations.},

abstract = {A systematic account of a diverse crinoid fauna from the Middle Jurassic (Upper Bajocian-Callovian) of the Polish Jura Chain and Holy Cross Mountains (south-central Poland) is presented. The description is supplemented with a list of all crinoid species found hitherto in the Tatra Mountains and the Pieniny Klippen Belt (Poland), which were a part of the northern margin of the Tethys during Middle Jurassic time. Balanocrinus hessi seems to be endemic and established its own population in the epicontinental sea. Other stalked crinoids entered from the Tethys through the East-Carpathian Gate or from a westerly way, and constitute a typical Mediterranean fauna. Stemless forms are regarded to be unsuccessful immigrants. The crinoid remains are preserved mostly as columnals and pluricolumnals, the majority of which are encrusted and bored by various epi- and endobionts. No encrustation or boring, however, occurred during the lifetime of these crinoids. The association of well-preserved columnals/pluricolumnals with the broken and abraded isolated columnals, may be the evidence of a within-habitat time-averaging of the crinoid assemblages. © 2007 Birkhäuser Verlag, Basel Zusammenfassung.: Aus mitteljurassischen (Bajocian-Callovian) Sedimenten des südlichen Zentralpolens (Krakow-Czȩstochowa Hochland und Heilig-Kreuz Gebirge) wird eine diverse Crinoidenfauna systematisch beschrieben und stratigraphisch eingestuft. Die Beschreibung wird durch eine Zusammenstellung sämtlicher Crinoiden-Spezies ergänzt, die bislang im Tatra-Gebirge und im Pieniny Klippen-Gürtel gefunden wurden. Beide Regionen waren während des Mittleren Jura Teil des Nordrandes der Tethys. Balanocrinus hessi bildete eigenständige Populationen in diesem epikontinentalen Meeresbereich und scheint endemisch gewesen zu sein. Andere gestielte Crinoiden drangen aus der Tethys durch die Ost-Karpaten-Pforte oder aus westlicher Richtung vor und stellen typische mediterrane Faunenelemente dar. Ungestielten tethyalen Formen gelang offensichtlich keine Einwanderung. Die Assoziation von gut erhaltenen Columnalien/Pluricolumnalien mit zerbrochenen und abgenutzten Columnalien könnte als 'time averaging' der Crinoidenvergesellschaftungen gesehen werden. © 2007 Birkhäuser Verlag, Basel.},

abstract = {Distinct faunal aggregates are described from the Middle Jurassic (uppermost Bajocian/lowermost Bathonian and Middle Bathonian) clay deposits of Czȩstochowa area, south-central Poland. These aggregates are composed of molluscs (scaphopods; gastropods; bivalves; ammonites and belemnites), articulate brachiopods and echinoderms (asteroids; crinoids and echinoids). A large percentage of the fossils, especially bivalves, are fragmented, but some fossils are complete. Although most of the fossils are crushed and fragmented, they are still identifiable to at least the genus level. Thorough statistical analysis of taphonomic features indicates that the preservation of asteroid marginal plates is distinct from the ossicles derived from the host clays. The high frequency of bite marks and the good state of preservation suggest that the accumulations are the products of predation activities and most probably are the effect of regurgitation. Taking into account the rich and diverse fauna, the predator was a bottom-feeding generalist. Possible predators include palaeospinacid sharks, a tooth of which was collected from the same bedding surface, but not associated with regurgitated remains. Although the bite marks on the asteroid ossicles point to sharks as potential producers of regurgitates, other vertebrates, like durophagous pycnodontiform fish, cannot be excluded. © 2007 The Authors, Journal compilation © 2007 The Lethaia Foundation.},

abstract = {Biomarkers are widely known to occur in the fossil record, but the unaltered biomolecules are rarely reported from sediments older than Paleogene. Polar terpenoids, the natural products most resistant to degradation processes, were reported mainly from the Tertiary conifers, and the oldest known are Cretaceous in age. In this paper, we report the occurrence of relatively high concentrations of ferruginol derivatives and other polar diterpenoids, as well as their diagenetic products, in a conifer wood Protopodocarpoxylon from the Middle Jurassic of Poland. Thus, the natural product terpenoids reported in this paper are definitely the oldest polar biomolecules detected in geological samples. The extracted phenolic abietanes like ferruginol and its derivatives (6;7-dehydroferruginol; sugiol; 11;14-dioxopisiferic acid) are produced only by distinct conifer families (Cupressaceae s. l.; Podocarpaceae and Araucariaceae), to which Protopodocarpoxylon could belong based on anatomical characteristics. Therefore, the natural product terpenoids are of great advantage in systematics of fossil plant remains older than Paleogene and lacking suitable anatomical preservation. © 2006 Springer-Verlag.},

abstract = {The pyrite framboid diameter and the extractable organic matter from the Middle Famennian rhythmic succession of limestones, nodular limestones and marly shales with pyritized fauna (KPG horizon) from the Holy Cross Mountains (Poland) were analyzed in order to constrain the water column structure during their deposition. In all samples investigated, small framboids (<5 μm) that may have formed in the water column occur but the majority of the framboids have larger diameters, characteristic for their formation within the sediments, below an oxic or dysoxic water column. This suggests that during deposition of the KPG horizon, the depositional environment was highly dysoxic, but not anoxic. Low concentration of the aryl isoprenoids and isorenieratane, and very high values of the AIR parameter point to the episodic photic zone euxinia and later post-depositional, partial degradation of the OM in suboxic conditions. Intermittent, but certainly short-lasting, anoxic conditions on the sea-floor, may also be supported by the lamination of the rock matrix and increased mortality of the juvenile ammonoids. The results of this study indicate that anoxic conditions prevailed in the shallow depths below the water-sediment interface, where pyritization following by dissolution of aragonitic shells of fauna occurred.

abstract = {Hiatus concretions are early-diagenetic sedimentary bodies, which in their history of formation, underwent exhumation during sedimentation break and/or erosion of sea-floor. Then they were colonized by various encrusters and borers, before they were buried again. Within Middle Jurassic (Bajocian through Bathonian) clays, hiatus concretions occur in four localities in the Cracow-Czestochowa Upland (south and central Poland): Ogrodzieniec, Bugaj, Mokrsko and Krzyworzeka. Preliminary data about their mineralogy, organic geochemistry and palaeoecology is given. Mineralogical analyses showed, that except dominant high Mg-calcite (up to 87.10% of total carbonates), concretions possess minor amounts of such compounds as quartz, clay minerals (kaolinite and illite), pyrite, siderite or Mg-kutnahorite. However high differences are observed between total organic carbon contents of concretions (TOC=0.460%) and surrounded clays (TOC = 2.16%), but their molecular composition is similar. Most of identified biomarkers are of terrestrial origin. In clay lithology, the hiatus concretions are the only sedimentary bodies that clearly mark the sedimentation pauses (hiatuses). In the investigated area, they form more or less continuous horizons. The concretions are calcitic, possessing various encrusting fauna such as bryozoans, oysters and oyster-like bivalves, serpulids, solitary corals and foraminifers. They often post-date the borings, belonging to such ichnogenera as Gastrochaenolites, Trypanites and Entobia. Some of the nodules show distinct transition from firmground (characterized by the presence of Glossifungites ichnocoenosis) to hardground (presence of Trypanites ichnocoenosis), pointing to the fact, that they formed at, or very close to, the sediment-water interface. Some concretions, like those from Bugaj and Mokrsko, are characterized by their high diversity of hard bottom communities. Those concretions are also irregular in shape; others, like those from Ogrodzieniec and Krzyworzeka, possess lower diversity. The concretions from Krzyworzeka are especially dominated by the borers, while the encrusters are sparse and not diverse. Those nodules that are wide and flat tend to be more bored on one surface only, while those that are more roundish, are bored on both sides more evenly. The degree of diversity is probably correlated with physical disturbance, causing the rolling and overturning of the exhumed concretions in the littoral zone. On the other hand, the overall diversity could be lowered due to destructive abrasion either of the shallowest borings, echinoid/gastropod scratch marks and shells of nestling bivalves, as well as more delicate epilithozoans.},
