Bystrowiana is an extinct genus of bystrowianid chroniosuchian from upper Permian deposits of Vladimir Region, Russia[1] and Jiyuan, China.[2] Chroniosuchians are often thought to be reptiliomorphs,[3] but some recent phylogenetic analyses suggest instead that they are stem-tetrapods.[4] The genus is named in honour of Dr. Alexey Bystrow, who was a Russian paleontologist. It was first named by Vyushkov in 1957 and the type species is Bystrowiana permira.[1] Two species—B. permira and B. sinica—are known.[5]
Bystrowiana is known from a 30 cm skull, which suggests it was a large animal, up to 2.5 m (8.2 ft) in total body length.[6]
