abstract = {A recent palaeontological investigation of Lower Devonian clastic strata from Poland has revealed the occurrence of a new type of palynomorph, which have elongate vesicles of variable proportions and exhibit bilateral symmetry. Three morphotypes were distinguished; two (Morphotypes A and B) have somewhat rounded poles without apertures, while the third (Morphotype C) has a thickened annular ring at the apex. The characteristic feature of Morphotypes A and C is a variable thickness of the vesicle at both poles, which makes the palynomorph approximately club-shaped. Morphotype B has an elongate, fusiform symmetrical shape. Some specimens are ornamented, showing irregularly distributed grains, but there are also ‘naked’ forms. The morphotypes generally occur as individuals but mono-taxonomic clusters were also observed. The biological affinity of these palynomorphs remains unclear. Some characters (morphology and shape) may indicate a relationship with arthropods, especially eurypterids. Other possibilities (acritarchs; testate amoebae; chitinozoa; fungi; algae) appear unlikely. The palynomorphs are from a coastal/alluvial environment, with a limited marine influence. © 2025 Elsevier B.V., All rights reserved.},

abstract = {The early radiation of dinosaurs remains a complex and poorly understood evolutionary event1, 2, 3–4. Here we use hundreds of fossils with direct evidence of feeding to compare trophic dynamics across five vertebrate assemblages that record this event in the Triassic–Jurassic succession of the Polish Basin (central Europe). Bromalites, fossil digestive products, increase in size and diversity across the interval, indicating the emergence of larger dinosaur faunas with new feeding patterns. Well-preserved food residues and bromalite-taxon associations enable broad inferences of trophic interactions. Our results, integrated with climate and plant data, indicate a stepwise increase of dinosaur diversity and ecospace occupancy in the area. This involved (1) a replacement of non-dinosaur guild members by opportunistic and omnivorous dinosaur precursors, followed by (2) the emergence of insect and fish-eating theropods and small omnivorous dinosaurs. Climate change in the latest Triassic5, 6–7 resulted in substantial vegetation changes that paved the way for ((3) and (4)) an expansion of herbivore ecospace and the replacement of pseudosuchian and therapsid herbivores by large sauropodomorphs and early ornithischians that ingested food of a broader range, even including burnt plants. Finally, (5) theropods rapidly evolved and developed enormous sizes in response to the appearance of the new herbivore guild. We suggest that the processes shown by the Polish data may explain global patterns, shedding new light on the environmentally governed emergence of dinosaur dominance and gigantism that endured until the end-Cretaceous mass extinction. © The Author(s) 2024.},

abstract = {Iceland, located in the climatologically sensitive subarctic zone, is one of the key areas for studying climate change and the current Arctic warming. Poor and rich heathland covers approximately 30% of Iceland, with heath vegetation being the area's most important vegetation type. Prostrate and erect dwarf shrub and shrub species are the primary sources of dendrochronological information on the changes and characteristics of Iceland's climate. Here, we investigate the dendrochronological potential of seven common Icelandic heathland species (Dryas octopetala; Calluna vulgaris; Salix arctica; Salix herbacea; Empetrum nigrum; Juniperus communis nana; and Betula nana) and explore the impact of climate conditions on their growth, particularly with regard to extreme meteorological events. We conducted comparative analyses among species and observed their climatic responses in a climatically, morphologically, and geologically homogeneous setting in north-eastern Iceland. After sampling, measurements, and cross-dating, we constructed local chronologies for the seven species. Of approximately 200 samples, only 113 were included in the final shrub chronologies. All chronologies covered at least 50 years, with few of them exceeding 100 years. Dendroclimatological analysis indicated that above-average temperatures in June and summer positively influence the growth of D. octopetala (June–September), J. communis (July–August), B. nana (July–August), C. vulgaris (June–August), and S. arctica (August–September). The opposite is observed for S. herbacea and E. nigrum. Climate–growth correlations indicate that the growth of these species is negatively correlated with temperature and positively correlated with winter and summer precipitation. Furthermore, among the long-lived woody species growing in Iceland, seven common species were used to assess the impact of extreme meteorological conditions on their growth. The most pronounced extreme year in the wood anatomy of Icelandic shrubs was 1979, depicted as very narrow or missing rings and as the blue ring in J. communis. © 2024 Elsevier GmbH},

abstract = {Upper Triassic fossil plants are well documented from the Keuper of Europe. Carnian and Rhaetian floras are rich in a variety of plant taxa, whereas in comparison, the Norian is limited to a few localities with poorly preserved fossil plant communities showing low diversification. The Norian Grabowa Formation in ZawiercieMarciszów, Upper Silesia, southern Poland, contains fossils of arborescent gymnosperms, including petrified conifer trunks. In this study, we present a fossil plant assemblage, containing fragmented plant parts in multiple forms of preservation, i.e., permineralised trunks and rooting structures, stems compressions, dispersed cuticles, and megaspores. Analysis of the macromorphological characters proved the presence of gymnosperms, including the arborescent conifer Agathoxylon cf. keuperianum, known already from this locality from fragments of charcoalified wood. Sphenophytes are represented by disarticulated stems of Equisetites sp., and Neocalamites sp. The variation in plant fossils indicates the possibility of higher plant diversity. Analysis of cuticles, macerated from different plant-bearing lithologies, revealed a variety of conifer foliage, expressed as five cuticulae dispersae morphotypes (needle-leaf Elatocladus-type and scale-leaf Pagio-Brachyphyllum-like). Plant fossils at Zawiercie-Marciszów are preserved in calcareous mudstones and micritic limestone concretions, developed in a fluvial environment. The presence of sphenophyte stems (Equisetites and Neocalamites) indicates that local conditions were more humid and suitable for spore-producing plants, appearing in the mid-Norian tectonic-pluvial episode, recorded in the Grabowa Fm. © 2023, Polish Geological Society.

abstract = {We present a preliminary assessment of a new Lower Devonian biota from an exposure of the Zagórze Formation at Bukowa Góra quarry in the Łysogóry Region of the Holy Cross Mountains, Poland. Abundant plant macrofossils preserved as carbonaceous compressions, adpressions, and permineralizations occur alongside a diverse assemblage of microfossils. Palynostratigraphic analysis places the fossiliferous sequences in the narrow Pro. Zone within the AP Zone of the douglastownense-eurypterota Miospore Zone, which corresponds to the upper part of the Emsian. Palynofacies analysis confirms that these sediments formed in a shallow-water, alluvial environment. The biota contains a rich assemblage of freshwater and brackish water organisms and fully terrestrial ones. Common elements include filamentous green algae, arthropods, terrestrial fungi-like filaments, nematophytes and abundant land plants. Scolecodonts and acritarchs are much rarer, suggesting limited marine influence. The new flora contains stem-group vascular plants, lycophytes and euphyllophytes. Among the permineralized remains is some of the earliest evidence of complex vascular systems, including cruciform and plate-like stelar organizations and secondary wood. We record the earliest fossil evidence of a dissected stele of the cladoxylopsid type. Innovations such as these were fundamental to the later evolution of arborescent growth in plants and the development of forest ecosystems. The biota complements and extends our knowledge of Emsian biotas in Euramerica just prior to the rapid changes that marked the Middle Devonian. It provides insights into a diverse early terrestrial community and raises further questions about the affinities and roles of arthropods and nematophytales in these ecosystems. © 2022 Elsevier B.V.},

Individual cells were arranged linearly and contacted each other. Specimens occurred as short filaments having no branches. Cell walls appeared single-layered, very thin and translucent. Cell surfaces were sometimes covered with very delicate striations, possibly generated by compressional folding. A comparison of the main features of the described taxa with extant algae indicated closest relationship with the chlorophycean green algal orders Ulotrichales and Cladophorales. Representatives of these orders occupy mainly freshwater environments. Palynofacies investigation revealed high content of land origin palynomorphs with complete lack of marine components. The presence of such delicate organisms as algae in sediments might indicate very fast deposition in a proximal, very near-shore, possibly shallow water/lagoonal or alluvial environment. © 2021 Elsevier B.V.},

abstract = {New fossil woods from the Keuper of Poland and France are assigned to Agathoxylon keuperianum (Unger) nov. comb. A complete nomenclatural treatment of this taxon is given, with up-dated nomenclatural synonymy and some taxonomical notes. It is shown that Zimmermann's choice of a lectotype (1953) for this species is superseded by material in the Unger collection at the Paris Muséum National d'Histoire Naturelle (France). Taxomical reappraisal of Unger collection also evidenced that Simplioxylon hungaricum Andreanzsky correct name is Simplicioxylon wurtembergicum (Unger) nov. comb. and that Peuce brauneana Unger can be excluded from Agathoxylon keuperianum synonymy. Literature data for Agathoxylon keuperianum are reviewed and some are invalidated. Our new data are the first safe reports for this species outside from Germany. The systematic position of Agathoxylon keuperianum is discussed, as well as its stratigraphical and geographical range. In the present state of knowledge it seems to be restricted to the area where German Keuper is deposited. Anatomical features suggest that Agathoxylon keuperianum thrived under warm and wet conditions, whereas German Keuper sediments globally suggest hot and dry climate. © 2015 Elsevier B.V.},
