“…Currently, the Owadów‐Brzezinki Quarry is the only location in extra‐Carpathian Poland where the uppermost lower Tithonian strata are available for study (Kin, Gruszczyński, Martill, Marshall, & Błażejowski, ). The palaeontological site located in the Owadów‐Brzezinki Quarry is one of the most important palaeontological discoveries described in recent years from Poland, where unusually well‐preserved fossils of terrestrial and marine organisms (including ammonites, horseshoe crabs, decapod crustaceans, insects, and remains of various fish and marine reptiles) have been discovered (Błażejowski, ; Błażejowski, Gieszcz, Brett, & Binkowski, ; Błażejowski, Lambers, Gieszcz, Tyborowski, & Binkowski, ; Kin & Błażejowski, , ; Kin, Błażejowski, & Binkowski, ; Kin et al, ; Tyborowski, ).

Numerous specimens of horseshoe crabs have been found in Unit III in association with an enormously rich assemblage (mass accumulations) of soft‐shelled bivalves, the remains of various fish and marine reptiles, rare ammonites, decapod crustaceans, land insects (dragonflies, beetles, and grasshoppers), and isolated pterosaurs' teeth (Błażejowski, ; Błażejowski, Lambers, Gieszcz, Tyboroski, & Binkowski, ; Błażejowski et al, ; Błażejowski et al, ; Kin & Błażejowski, ; Kin et al, ).

A new pancryptodiran turtle from the Late Jurassic of Poland and palaeobiology of early marine turtles

Although Western Europe has yielded numerous Jurassic turtle taxa, several represented by cranial material or complete skeletons, the fossil record of the Jurassic turtles remains scarce to the north and east from Germany. Although some Late Jurassic testudinates were historically described from Poland, they were, thus far, represented by fragmentary remains that never were properly figured or described in detail. Therefore, very little is known about the mid‐Mesozoic diversity of turtles in that region of the continent. A new pancryptodiran turtle genus and species, Owadowia borsukbialynickae, is described from the uppermost Jurassic (Tithonian, ca. 148 Ma) carbonate sediments of the Kcynia Formation in Owadów‐Brzezinki Quarry, near Tomaszów Mazowiecki in central Poland. The lower jaw morphology and palaeoecological setting inhabited by the new genus and species, together with the trophic relationships of the Jurassic pancryptodiran turtles, are discussed in an attempt to determine the potential range of mode of life of O. borsukbialynickae. We propose that the new specimen belongs to a new durophagous pancryptodiran turtle taxon. O. borsukbialynickae might have spent considerable time in the marine environment and specialized on eating hard‐shelled invertebrates like bivalves and decapod crustaceans, common to that setting.

Taxonomic status of the caturid genera (Halecomorphi, Caturidae) and their Late Jurassic species

Caturids are among the best-known predatory ray-finned fishes of the Mesozoic. Although there is consensus about their sister-group relationship to Amiidae (Holostei, Amiiformes), their diversity, ingroup phylogenetic relationships and evolutionary history are still very poorly understood. Caturidae is currently restricted to Caturus and Amblysemius , each with two species. Among them, C. furcatus has become the wastebasket taxon for the group. Our revision of nearly 40 species based on the original descriptions, type and referred material led to significant results changing the picture of caturid diversity in the Late Jurassic. Four specific names are unavailable. Due to insufficient information in the original descriptions, lack of diagnostic features in the type material, or the complete lack of type material, 13 nominal species are nomina dubia. Two species currently considered junior synonyms represent distinct taxa. Strobilodus giganteus is removed from Caturidae. Caturus cliftoni , Thlattodus and Ditaxiiodus are tentatively referred to Strobilodus . The fossil record of Caturoidea is restricted to the Jurassic and earliest Cretaceous. The group apparently underwent significant diversification during the Late Jurassic, as indicated by the increase in the number of taxa and the dispersal of the group outside Europe, which had already begun in the Middle Jurassic.

“…There were many discoveries of marine life made in the Owadów-Brzezinka quarry, both of invertebrates -incl. ammonites (Matyja & Wierzbowski, 2016), decapod crustaceans (Glypheoidea: Mecochiridae; Feldmann et al, 2015), horseshoe crabs (Chelicerata: Xiphosura; Błażejowski, 2015; Błażejowski et al, 2015aBłażejowski et al, , 2020Backnell et al, 2021) and vertebrate: the remains of various fish (Osteichthyes: Actinopterygii; Błażejowski et al, 2015b;Tyborowski, 2017), marine reptiles (Tyborowski et al, 2016): pancryptodiran turtle (Testudinata: Pancryptodira; Szczygielski et al, 2017) and ichthyosaurs (Ichthyosauria: Ophthalmosauridae; Tyborowski, 2016). The vast majority of the identified fossils represent hitherto unknown species, and their scientific description represents a significant contribution to understanding the life history of these groups of animals (Kin & Błażejowski, 2014;Błażejowski et al, 2016).…”

The geoeducation area (called also “Owadów-Brzezinki Geopark”) located in the north-western margin of the Holy Cross Mountains (Tomaszów Syncline) at Sławno community (Łódź Voivodeship), was established in June 2019, in close vicinity of the Owadów-Brzezinki quarry. This locality is one of the most important palaeontological sites described recently in Poland. The area consists of the exhibition pavilion, educational routs and panoramic viewing platform, which is located along the edge of the quarry. The palaeontological exhibition shows the unique Late Jurassic fossils of marine and terrestrial organisms, many of them new to science, that have been excavated in the quarry during the last eight years. Among the most important fossils are: ammonites, lobster-like decapod crustaceans, horseshoe crabs, actinopterygian fish, a cryptodiran turtle, ichthyosaurs, as well as a small terrestrial crocodyliform, pterosaurs and insects. In addition to the original fossils, the exhibition presents life-size reconstructions of animals, that inhabited the local seas and islands during the Late Jurassic. The palaeontological sites of Owadów-Brzezinki is referred to as a new “taphonomic window” of the Late Jurassic, providing insights about the evolution of life on Earth in the palaeogeographical and palaeoenvironmental context.
