Abstract—The most complete specimen of the plesiosaur genus Polycotylus from the Upper Cretaceous of the
southern Urals is described. This specimen has much in common with the species P. latipinnis described from
North America, but differs in the limb structure and cranial bones, so that it is assigned to a separate species,
Polycotylus sopozkoi sp. nov.

Keywords: Polycotylidae, plesiosaurs, Late Cretaceous, Russia, southern Urals, Orenburg Region, Izhberda
