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

Acknowledgments. My sincere thanks to A.Z. Bikbaev (Leading Engineer) and M.P. Snigireva (PhD in Geology and Mineralogy, Leading Engineer) from Zavaritsky Institute of Geology and Geochemistry, Ural Branch, Russian Academy of Sciences for providing the collection and the stratigraphic data, as well as to N.S. Vlasenko (Engineer, St. Petersburg State University) and R.A. Rakitov (PhD in Biology, Senior Scientist, Borissiak Paleontological Institute, Russian Academy of Sciences) for their assistance with SEM imaging.
