A description of the most complete remains discovered of the plesiosaur genus Polycotylus from the Upper Cretaceous of the Southern Ural. This find is in many ways similar to the species P. latipinnis described from North America, but there are significant differences in the structure of the limbs and bones of the skull that allow assignment to a separate species, Polycotylus sopozkoi sp. nov.
