Abstract

A new and most ancient species of the genus Pinna, P. pacata sp. nov., has been described from the Lower Permian deposits of the Shakhtau reef (southern Urals, Russia). Until now, the most ancient finds of representatives of this genus were known from the Lower Triassic. The new species adds to the list of species ancestral to Mesozoic forms, which makes it possible to consider the Ural Strait as one of the centers of Late Paleozoic mollusk diversification.
