Osmolskina (named after Halszka Osmólska) is a genus of archosauriform reptile from the Poland, Europe. It lived during the Olenkian stage of the Early Triassic epoch. It is monotypic, with the only known species being Osmolskina czatkoviensis.
History of research[]
Cranial elements of Osmolskina czatkoviensis, from Magdalena Borsuk-Białynicka and Susan E. Evans (2003)[1]
Remains of this animal were found in a karst fissure in the Czatkowice quarry near Cracow, Poland. The fossils were catalogued as ZPAL R−I/77 at the Institute of Palaeobiology Polish Academy of Sciences in Warsaw. They were described in 2003 by Magdalena Borsuk−Białynicka and Susan Evans as a new genus and species of euparkeriid, Osmolskina czatkoviensis.
The specific epithet references the locality in which the reptile was discovered. The genus name honors Halszka Osmólska, a Polish fossil collector.
In 2009, additional material assigned to O. czatkoviensis was reported from Czatkowice quarry. Comprising it was numerous disarticulated postcranial material, including scapulae, caracoid vertebrae, and limb bones.[2]
Paleobiology[]
The typical skull length of Osmolskina is 60 mm (2.36 in). The known material belonged to multiple individuals, though, some of which may have had skulls measuring 120 mm (4.72 in) long. The teeth are typical for archosauriforms, being thecodont (deeply set in jawbone sockets) and laterally compressed with serrated edges. [1]
Affinities[]
Osmolskina is tentatively assigned to the Euparkeriidae family. It was a close relative of Halazhaisuchus and Euparkeria.
Paleoecology[]
Like it's more famous relative of Euparkeria, Osmolskina is likely an insectivore.
Czatkowice quarry, Poland, preserved an ecosystem from the Olenkian stage of the Triassic period. Also known from the quarry are diapsid reptiles, procolophonians, fish, rare temnospondyls, and the stem frog Czatkobatrachus polonicus.[3] Collilongus rarus was another archosauriform living there.
Osmolskina expands the range of eurparkeriids in Gondwana.
