    Opis:
    The Early Triassic record of the large capitosaurid amphibian genus Parotosuchus is supplemented by new material from fluvial deposits of Wióry, southern Poland, corresponding in age to the Detfurth Formation (Spathian, Late Olenekian) of the Germanic Basin. The skull of the new capitosaurid shows an “intermediate” morphology between that of Paroto− suchus helgolandicus from the Volpriehausen−Detfurth Formation (Smithian, Early Olenekian) of Germany and the slightly younger Parotosuchus orenburgensis from European Russia. These three species may represent an evolutionary lineage that underwent a progressive shifting of the jaw articulation anteriorly. The morphology of the Polish form is dis− tinct enough from other species of Parotosuchus to warrant erection of a new species. The very large mandible of Parot− osuchus ptaszynskii sp. nov. indicates that this was one of the largest tetrapod of the Early Triassic. Its prominent anatomi− cal features include a triangular retroarticular process and an elongated base of the hamate process.

    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:
    This paper describes the vertebrate ichnofauna from the Tumlin Sandstone (Buntsandstein) of the Holy Cross Mountains in Poland. The footprint assemblage has previously been regarded as Early Triassic in age; however, ichnogenera characteristic of the Late Permian are now recognized. Lack of representatives of the ichnofamily Chirotheriidae, characteristic of continental Triassic sediments worldwide, also indicates a Permian rather than a Triassic age for the studied assemblage. Three ichnogenera (Batrachichnus, Limnopus, and Amphisauropus) produced by amphibians are recognized, the remainder (Varanopus, Chelichnus, Dimetropus, Rhynchosauroides, Palmichnus, Paradoxichnium, and Phalangichnus) being of reptilian origin. Batrachichnus cf. salamandroides (Geinitz, 1861), Limnopus cf. zeilleri (Delage, 1912), Amphisauropus cf. latus Haubold, 1970, Varanopus aff. microdactylus (Pabst, 1896), Chelichnus cf. duncani (Owen, 1842), and Dimetropussp. are recorded in the Lower Buntsandstein for the first time. The following new ichnospecies are erected: Rhynchosauroides kuletae ichnosp. nov., Palmichnus lacertoides ichnosp. nov., Paradoxichnium tumlinense ichnosp. nov., Phalangichnus gradzinskii ichnosp. nov., and Phalangichnus gagoli ichnosp. nov.

    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:
    We describe a new large predatory archosaur, Smok wawelski gen. et sp. nov., from the latest Triassic (latest Norian–early Rhaetian; approximately 205–200 Ma) of Lisowice (Lipie Śląskie clay−pit) in southern Poland. The length of the reconstructed skeleton is 5–6 m and that of the skull 50–60 cm, making S. wawelski larger than any other known predatory archosaur from the Late Triassic and Early Jurassic of central Europe (including theropod dinosaurs and “rauisuchian” crurotarsans). The holotype braincase is associated with skull, pelvic and isolated limb−bones found in close proximity (within 30 m), and we regard them as belonging to the same individual. Large, apparently tridactyl tracks that occur in the same rock unit may have been left by animals of the same species. The highly autapomorphic braincase shows large attachment areas for hypertrophied protractor pterygoideus muscles on the lateral surface and a wide, funnel−like region between the basal tubera and basipterygoid processes on the ventral surface. The skeleton (cranial and postcranial) possesses some features similar to those in theropod dinosaurs and others to those in large crocodile−line archosaurs (“rauisuchians”), rendering phylogenetic placement of S. wawelski difficult at this time.

    Opis:
    The German Late Triassic archosaur Teratosaurus suevicus is a historically important taxon, being the first described rauisuchian. Unfortunately the holotype is a single element, a maxilla, which is poorly preserved and incomplete. We redescribe this maxilla and identify a single potential autapomorphy. The fragmentary type specimen complicates attempts to refer additional material to this taxon, and other unassociated archosaur and rauisuchian specimens from the Mittlerer Stubensandstein of Germany cannot be referred to T. suevicus with any degree of confidence. The stratigraphically older T. silesiacus, from the upper Carnian of Poland, is represented by a much more complete and better preserved specimen. Comparison of the maxillae of T. suevicus and T. silesiacus reveals that the two are distinct taxa, contra recent suggestions, but also that they do not share any synapomorphies or a unique combination of characters relative to Postosuchus kirkpatricki and other rauisuchians. Thus, the Polish material must be transferred to a new genus, Polonosuchus gen. nov. Both Polonosuchus and Teratosaurus are very similar to Postosuchus kirkpatricki, and the three taxa are likely closely related.
