Abstract
For the first time in the Lower Permian deposits (Upper Asselian–Sakmarian stages) of the Southern Cis-Urals, the most ancient representatives of oyster-like bivalves of the genus Prospondylus Zimmermann were found, reliable findings of which were previously known only in the Lower-Middle Permian deposits of North America and the Upper Permian deposits of Germany. A description of the new species Prospondylus shakhtauensis Biakov, sp. nov. is given.
