Abstract


A POSSIBLE PEDOCNEMIDIDAE (PLEURODIRA: PELOMEDUSOIDES) FROM THE LATE CRETACEOUS OF PATAGONIA. PALAEOBIOGEOGRAPHIC IMPLICATIONS. The first Patagonian Pelomedusoides from Late Cretaceous sediments in Neuquén province, Argentina, is described. This turtle represented by a single shell, incompletely preserved, is tentatively referred to the Podocnemididae. It appears to be more plesiomorphic by some characters, than the species of the Roxochelys group. Its close relationship with the paleocene species "Podocnemis" argentinensis Cattoi & Freiberg, 1958 from northwestern Argentina, shows the expansion of the Pelomedusoides fauna from the Andean basins to Patagonia.
