    vertebrate footprints
    Opis:
    New specimens of vertebrate footprints are reported from the Early Permian deposits in Poland. Footprints discovered in a well-known Early Permian Rotliegend tracksite at Wambierzyce (old German name Albendorf) represent ichnites of Hyloidichnus arnhardti Haubold, 1973.

    Opis:
    The study was performed to attempt the lithostratigraphic correlation of the Buntsandstein in the margin of Holy Cross Mountains region with that of the Thuringian Basin, and simultaneously, to clarify its position in the chronostratigraphic scheme, basing on biostratigraphic data (microflora, conchostracans), and on the existence of regional discordances. The authors found strong analogies with other Buntsandstein sections of the Europe. On the other hand, because of the position of the studied area within the marginal part of the Central European Basin, Buntsandstein of the Holy Cross Mountains region is developed in different facies, more fluvial, instead of lacustrine ones. The common presence of Conchostraca representing the same species as in other parts of the Central European Basin (Thuringia), enables possible the correlation of the investigated area with the Thuringian Basin, and helps to locate stratigraphic gaps and discordances. The authors found that the lower boundary of the Buntsandstein and the boundary between the Lower and Middle Buntsandstein in the Polish study area are not equivalents of those in other areas. Also note worthy is the presence at the margin of the Holy Cross Mountains of youngest Permian terrigenous deposits not connected with the Zechstein salinar sedimentation, included to date to Zechstein or to Buntsandstein. The key for understanding the lithostratigraphic scheme of the Buntsandstein of Holy Cross Mountains region is an assumption, that the Zagnańsk Formation is mostly of fluvial, instead of lacustrine origin, consisting of equivalents of the whole Lower Buntsandstein, and that of the lower Volpriehausen Formation of the Middle Buntsandstein, with the Volpriehausen discordance present within. Authors also assume, that at least in this case, differences in the marginal part of the sedimentary basin, in comparison with its central part, depend on the presence of fluvial facies instead of lacustrine ones, and onthe presence of sedimentary gaps and discordances whose duration is progressively longer towards the basin margin enlarges in the direction to the basin margin.

    Opis:
    Vertebrate remains, mostly nothosaurid vertebrae and long bones, archosaur partially preserved long bones and teeth (probably rauisuchid remains), fish teeth and scales, are described from the Lower Keuper Miedary Beds (Ladinian, Middle Triassic) of Miedary, Silesia, SW Poland. The analyzed vertebrate fossils were collected from three lithologically different types of deposits. The first assemblage, which contains nothosaurid and fish remains, occurs in yellowish dolomites, where poorly preseved invertebrate macrofossils were also found (marine bivalves and brachiopods). In grey-yellowish, sometimes greenish or red clays, rare isolated bones and teeth of large archosaur were found. In sandstone intercalations partially preserved and highly disarticulated fish fossils were identified. In all assemblages osteological remains are generally very well preserved. This new interesting vertebrate bones association from the upper part of the Middle Triassic marginal-marine strata of Poland has been correlated with age-equivalents from other regions of Europe.

    Late Triassic
    Opis:
    It is generally accepted that during the Triassic the composition of tetrapod faunas underwent a series of fundamental transformations, mainly as a result of diversification of archosaurs and decline of therapsids (Benton 1994, 2004, 2006). The last herbivorous basal synapsids, dicynodonts, disappeared from the record in the early Norian of the Americas, about 220 Ma (Langer et al. 2007), being unknown from the Late Triassic of Europe. Here, we report a partially articulated skeleton and isolated bones of a giant rhino−size dicynodont in the Upper Triassic fluvial sediments at Lisowice (Lipie Śląskie clay−pit) in southern Poland. Paleobotanical data indicate an early Rhaetian age for the fauna (Dzik et al. 2008; Niedźwiedzki and Sulej 2008). The dicynodont bones are associated with bones of carnivorous dinosaurs, pterosaurs, as well as capitosaur and plagiosaur amphibians. Dicynodonts were represented in the Germanic Basin throughout the Late Triassic, as proven by findings of smaller dicynodonts in older deposits in the same area, associated there with temnospondyl amphibians. It appears, thus, that the fossil record of tetrapod succession in the Late Triassic was strongly controlled by ecological factors and biased by uneven representation of particular environments. The Lisowice assemblage proves that faunas dominated by dicynodonts did not entirely disappear at least until the end of the Triassic.

    Opis:
    Vertebrate footprints are abundant in the Buntsandstein of the Holy Cross Mountains (central Poland) and have been documented in numer-ous publications. A new site vertebrate trackside has been discovered in near Suchedniów. Chirotheriidae (Synaptichnium sp., Chirotherium barthii, and Brachychirotherium sp.), Rhynchosauroidae (Rhynchosauroides sp.), and probably amphibian footprints (cf. Capitosauroides sp.) are reported from the lower part of the Upper Buntsandstein Baranów Formation (complex of different fluvial deposits) exposed at Kopulak quarry. Differentiated invertebrate ichnofossils (Cruziana problematica, Scoyenia sp., Palaeophycus sp., Skolithos sp., Lockeia sp., and cf. Gordia sp.) and plant remains have been also found in this site. Three types of vertebrate subaqueous traces (footprints of swimming animals) are identified: (1) swim traces - structures preserved as digits or claws scratches; (2) partially preserved pes or manus imprints; (3) other enigmatic traces -referred to as “problematic forms”.

    Opis:
    Here we present a description of the dipnoan remains collected from the middle to upper Norian (Upper Triassic) of Jameson Land, East Greenland. The specimens consist of isolated tooth plates and skull bones of Ptychoceratodus, the most complete Late Triassic dipnoan material from Greenland. This genus is reported for the first time from the Upper Triassic of Greenland. The studied material belongs to Ptychoceratodus rectangulus previously known from the middle–upper Norian of Germany. It fills the biogeographical gap between the records of the Germanic and the Jameson Land basins. A reconstruction of the skull roof is provided, based on isolated bones collected from the same bone-bed. Their good preservation enables recognition of the sensory line pits, arranged similarly as in the extant Protopterus, suggesting a comparable mode of life. This finding has implications for our understanding of the disparity in Ptychoceratodus dipnoans, as well as the morphology between closely related dipnoans of the Late Triassic ecosystems.

    Opis:
    A unique functional adaptation to herbivory within early ray-finned fishes is exemplified by the late Permian actinopterygians within the family Eurynotoidiidae with policuspid teeth strongly modified with respect to the primitive actinopterygian conditions. Here we report additional finds of multidenticulated teeth from the fluvial latest Permian deposits of Russia. The teeth belong to the members of endemic Eurynotoidiidae and show rather high morphological diversity. We confirm that the Russian forms are the earliest known ray-finned fishes with substantial modifications of teeth adapted to the processing of food. These finds confirm some previous suggestions that the adaptation to herbivory first developed in freshwater fishes, not marine. We found very similar dental adaptations in some groups of Recent freshwater teleosts, especially in characiforms and cichlids. It suggests that sympatric species of Permian Eurynotoidiidae explored various herbivorous niches like modern fish in East African lakes. Apparently, this first pulse of adaptive radiation in ray-finned fishes was probably caused by diversification of Permian aquatic vertebrate community.
