Venyukovioidea
Venyukovioidea is an infraorder of anomodont therapsids from the Permian of Russia. It includes the genera Otsheria, Venjukovia, Ulemica, and Suminia. Venyukovioidea and Dromasauria were traditionally considered the two main groups of basal anomodonts. Dromasauria was considered a Gondwanan group while Venyukovioidea was a Euramerican group. More recent studies consider Dromasauria to be paraphyletic. Venyukovioidea is thought to have arisen from basal anomodonts in Africa and underwent an evolutionary radiation in Russia.
