Ichthyofauna of the border sediments of the Severodvinsky and Vyatsky stages in the Late Permian localities in the west of the Orenburg region (Samara river basin)

A detailed study of the section of the severodvinsky and vyatsky stages of the Upper Permian with layer-by-layer sampling of ichthyofauna in the western part of the Orenburg region (basin of the lower reaches of the Samara River) was carried out. Based on the fish complexes, a paleontological justification of the stratigraphic boundary between the severodvinsky and vyatsky stages was obtained in the region for the first time.
