Abstract

New assemblages of diverse fishes from the Givetian–Famennian were described in six sections in the Middle Urals: Pokrovskoe, Baronskaya, Sulem, Pershino, Yokva, and Vilva. Diademodus, Wellerodus, and Mimipiscis genera were discovered in the Urals for the first time. Data on the occurrence of Phoebodus species in the Pokrovskoe section were used to specify the boundary between the Phoebodus sophiae and Ph. latus phoebodontid zones. Four phoebodontid zones can be recognized in the sections of the Middle Urals.

Keywords: fishes, Devonian, Middle Urals
