Kotel'nich Tetrapod Assemblage

Summary

The Kotel'nich Tetrapod Assemblage is a tetrapod assemblage zone in Russia. Its fossils are from "a red-coloured predominantly clay-argillite-siltstone sequence exposed on the right bank of the Vyatka River south of the town of Kotel’nich". It is dated to the late Capitanian age of the Middle Permian. The type locality is in the Vanyushonki Member of the Vyatka Formation. The upstream Port Kotel'nich locality, dominated by dicynodonts of genus Australobarbarus, was traditionally also included in this assemblage; however, this is now questioned due to fossil and possible time differences.
