Abstract

Viatkogorgon ivachnenkoi Tatarinov is a small gorgonopian with well-developed gastralia and hypapophyses of the caudal vertebrae and broad and short feet with distal intertarsal contacts. This animal was apparently a relatively good swimmer. The gastralia of Viatkogorgon were acquired secondarily (punctuated homology).
