The first tetrapods entered continental communities as consumers of
the highest order, forming the subdominant and aquatic tetrapod
communities. At the end of the Carboniferous, herbivorous tetrapods
appeared in North America and Western Europe; the first
(pelycosaurian) dominant tetrapod communities were formed. In the
Middle Permian, dominant communities are already known in all
continents, where they are formed by Dinocephalian (therapsid) faunas.
The history of the Dinocephalian fauna is most completely represented
in the fossil record of South Africa and Eastern Europe. In the East
European region, it is represented in the Mezen, Golyusherma, Ocher,
Isheevo, and Sundyr assemblages, displaying successive stages of
phylocoenogenesis of Dinocephalian community. The major features of
these stages are considered. In the terminal Middle Permian
(Guadalupian), Dinocephalian communities were disintegrated worldwide.
In Eastern Europe, this occurred during the Severodvinian ecosystem
crisis. The main features of the Severodvinian crisis are discussed.
