The vertebrate fossil record of the Guabirotuba Formation, Curitiba Basin (Cenozoic), South Brazil, was restricted to a crocodyliform tooth and indeterminate bone fragments. New specimens collected in an outcrop located in Curitiba city, in the State of Paraná, are herein described and represent the first record of Pleurodira (Testudines) to this basin. The presence of aquatic Testudines associated to Crocodyliformes corroborates the lacustrine and fluvial paleoenvironment for the Guabirotuba Formation deposition and indicates a more humid climate than previously proposed.
Keywords: Testudines, Pleurodira, Curitiba Basin, Guabirotuba Formation, Cenozoic.
