Redescription of cranial and post-cranial anatomy of Bauruemys elegans from Upper Cretaceous of Bauru Basin and its phylogenetical position within Epifamily Podocnemidinura (Pelurodira, Pelomedusoides) / Redescrição da anatomia craniana e pós-craniana do fóssil Bauruemys elegans (Suárez, 1969) do Cretáceo Superior da Bacia Bauru e seu posicionamento filogenético dentro da Epifamília Podocnemidinura (Testudines, Pelomedusoides).

RESUMO

In this study, the fossil Bauruemys elegans is redescribed. Its cranial and postcranial anatomy was analysed in detail based on new specimens collected. Bauruemys elegans is a chelonian from Upper Cretaceous of the Bauru Basin founded in the municipality of Pirapozinho, São Paulo state and was originally described by Suarez (1969) as Podocnemis elegans. The specimens analysed was compared with some extant representatives of Chelidae, Pelomedusidae and Podocnemididae families and descriptions avaliable on the literature. The phylogenetic affinities of the Bauruemys elegans within Podocnemidinura was evaluated through a parsimony analysis envolving 19 taxa and 56 characters. The results of phylogenetic analysis shows that Bauruemys elegans is, in fact, a distinct genus within the clade Podocnemididae. This corroborated anterior hypothesis proposed. Adittionally, this analysis using osteological characters, indicate Bauruemys elegans as the sister group of Cambaremys langertoni and Podocnemididae.
