During a detailed archival query carried out for the implementation of the Koszalin sheet of The Geological Map of Poland, scale 1 : 200 000, cartographers from the Polish Geological Institute found original materials from a research borehole made in 1938 in the Darłowo (Rügenwalde) region. It was determined that in the drill core, in sediments dated to the Early Triassic, contained a reptile vertebra, which has survived to the present day and is in the collection of the Bundesanstalt für Geowissenschaften und Rohstoffe in Berlin. Thanks to international cooperation, it was possible to re-analyse the specimen bya team of palaeontologists from the Institute of Paleobiology of the Polish Academy of Sciences. The specimen, which was located after 85years, is not only a historical curiosity, but can also be of great importance to science. It is the only Triassic tetrapod fossil from Pomerania and potentially one of the oldest tetrapod remains not only in Poland, but also in Europe.

Neutron scans of a concretion with a 3-dimensionally preserved partial skull from the Lower Triassic Vega Phroso Siltstone Member of the Sulphur Mountain Formation (western Canada), previously assigned to Caseodus, reveal that upper jaws were absent in this eugeneodontid. Large, anteriorly deep lower jaws housed relatively few and large tooth files and enclosed a narrow anterior mouth cavity together with the symphysial tooth whorl, which is situated on the mandibular rostrum. The symphysial teeth are slender-conical in antero-occlusal view and do not appear to possess a transversal crest. The taxonomic significance of tooth morphology and absence of upper jaws is discussed. This eugeneodontid yields evidence of another group of rather primitive fishes surviving the end-Permian extinction event. The architecture of oral cavity and dentition suggests these chondrichthyans were specialized on preying on disc-shaped or flat, presumably shelled organisms.

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”.

W utworach międzywydmowych piaskowców tumlińskich pstrego piaskowca, w kamieniołomie na Górze Grodowej, znaleziono bogaty zespół tropów kręgowców. Oznaczone dotychczas ichnotaksony: Amphisauropus cf. latus, Rhynchosauroides cf. pallini, Varanopus cf microdactylus, Palmichnus sp., Chelichnus ? sp., "Proterosuchia indet. " były dotychczas znane z utworów permu Europy i Ameryki Północnej. Zespół ten, niewiele starszy od zespołu tropów kręgowców z warstw łabiryntodontowych z Wiór koło Ostrowca Świętokrzyskiego zawierającego typową dla triasu ichnofaunę wskazuje, że wyraźna zmiana zespołu ichnofauny kręgowców w pobliżu granicy permu i triasu nastąpiła w Górach Świętokrzyskich dopiero we wczesnym triasie.

Rich vertebrate track assemblage has been found in the interdune deposits of Tumlin sandstone of the Buntsandstein at the quarry of Grodowa Hill. The ichnotaxa which have been hitherto designated as Amphisauropus cf. latus, Rhynchosauroides cf. pallini Varanopus cf. microdactylus, Palmichnus sp., Chelichnus ? sp., "Proterosuchia indet. " have been hitherto known from the Permian of Europe and North America. This assemblage as only somewhat older than the vertebrate footprint assemblage from Labyrinthodontidae Beds from Wióry near the town of Ostrowiec Świętokrzyski containing typical Triassic ichnogenera representafives shows, that a distinct change of terrestrial vertebrate ichnofauna near the Permian/Triassic boundary occurred in the Holy Cross Mts. area in the Early Triassic time.
