The Succession of the Permian Tetrapod Fauna of Eastern Europe and the Permo-Triassic Ecological Crisis
The most complete continuous section of the continental Permian and Triassic deposits in the world is represented in Eastern Europe. It makes it possible to trace the development of tetrapod faunas more than seventeen consecutive successive stages. The newly obtained data on transition Vyazniki and newly discovered Sundyr tetrapod faunas allow more precisely characterize the Late Guadelupian (Pre-Lopingian) and the End-Permian ecological crises and ways to replace the dominant vertebrate groups on the territory of Eastern Europe.
