Bystrowiella is an
extinct genus of bystrowianid chroniosuchians from upper Middle Triassic (Ladinian age) deposits of Kupferzell and Vellberg, northern Baden-Württemberg, Germany.[1]
Discovery and naming
It was first named by Florian Witzmann, Rainer R. Schoch and Michael W. Maisch in
vertebrae (SMNS 81698, 81871–81874, 81876, 81877, 81879). The type species is Bystrowiella schumanni. The genus is named in honour of Dr. Alexey Bystrow, a Russian paleontologist and the species in honour of Schumann family. Bystrowiellas closest relative was Synesuchus.[1]
B. schumanni is the first bystrowianid identified outside Russia and China.[2]
Description
Bystrowiella is known by cranial and postcranial material. The
amniotes. The interclavicle is thin, with a distinct parasternal process; the humerus is narrow, with a short supinator process; trunk ribs are long and curved, with thin shaft without additional protrusions; the rib heads are widely spaced.[2]
Phylogeny
Is was assigned to bystrowianids due to the characteristics of the vertebrae and osteoderms.[2] Below is a cladogram after Novikov (2018) showing internal relationships of bystrowianids based on differences in their osteoderms:[3]
