This article describes turtle taxa from Upper Cretaceous deposits, revealing new findings in Eurasia.
The article describes a turtle assemblage from the Upper Cretaceous deposits of the Izhberda locality in the Orenburg Region of Russia. The assemblage contains at least four taxa of sea turtles: Protostegidae indet., Toxochelyinae indet. (the first reliable find in Eurasia), Ctenochelyidae indet., and Pan-Chelonioidea indet., similar to Corsochelys haliniches Zangerl, 1960. In addition, remains of Pan-Chelonioidea indet., which may belong to a wide range of taxa, and a fragment of a sculptured peripheral plate of Testudines indet., which may belong to a representative of the genus Peritresius (Ctenochelyidae) or a large representative of Nanhsiungchelyidae (previously not reported in Europe), are described.
