A revision of the holotype of Nanhsiungchelys wuchingensis, Ye, 1966 (Testudines: Cryptodira: Trionychoidae: Nanhsiungchelyidae).

Abstract Nanhsiungchelys wuchingensis Ye, 1966 is the type genus and species of the family Nanhsiungchelyidae (Testudines: Cryptodira: Trionychoidae) known from the Cretaceous continental deposits of Asia and North America. The holotype of this species (IVPP V 3106), a partial skeleton from the uppermost Cretaceous of Nanxiong Basin, southern China, represents one of the most complete specimens of that family. Our revision provides new insights on the skeletal morphology. The structure of the forelimb supports a terrestrial mode of life. The phylogenetic relationships are discussed and the more precise stratigraphical information is provided. [ABSTRACT FROM AUTHOR]
