Bystrowiana

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 the Russian paleontologist Alexey Bystrow.

[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.
