Abstract

This article describes remains of sea turtles (clade Pan-Chelonioidea) from three Upper Cretaceous localities of the Penza Oblast in Russia: Malaya Serdoba 1 and Malaya Serdoba 2 (Campanian) and Penza (Maastrichtian). The distal part of the humerus of Pan-Chelonioidea indet. from the Malaya Serdoba 1 locality is similar to the humerus of Terlinguachelys fischbecki (Protostegidae) from the Campanian of the United States. The turtle assemblage from the Malaya Serdoba 2 locality includes Protostega gigas (Protostegidae) and Pan-Chelonioidea indet., which are similar to T. fischbecki and representatives of the clade Ctenochelyidae, and resembles the sea turtle assemblage from the Campanian Beloe Ozero locality, Saratov Oblast (Russia) in systematic composition. The external surface of the turtle costal plates from the Penza locality has an ornamentation similar to Peritresius ornatus (Ctenochelyidae) and Glyptochelone suyckerbuycki.
