Eastern Europe

Ichthyofauna from the Key Sections of the Middle and Upper Permian of Eastern Europe. Complexes and Zonal Scale. Paper 2: Basin of the Volga and the Ural Rivers

Material on ichthyofauna from the Middle and Upper Permian of Eastern Europe was revised. New fish taxa from the Permian key sections of the basin of the Volga and the Ural Rivers significantly expanded composition of the complexes. the stratigraphic and geographical distribution of fish has been traced. A more precise zonal scale of the Middle and Upper Permian of the Eastern Europe based on ichthyofauna has been proposed. 

New data on the Late Permian actinopterygian fish Toyemia Minich, a zonal genus of the Permian biostratigraphic scheme based on ichthyofauna from the Eastern Europe

The structure of the actinopterygian fish genus and speciesToyemia tverdochlebovi Minich has been completed for the first time using a previously unknown complete skeleton and skeletal fragments from Late Permian localities of Eastern Europe. The structure of a head which so far remained unknown in the genus is described. The dorsal fin location far from the head near the caudal region was confirmed as expressed earlier by the taxon’s author.
