Physa mezzalirai n. sp. (Family Physidae, Order Basommatophora), a fresh-water gastropod is described from sand-silty beds of Adamantina Formation (Bauru Basin), Late Cretaceous of São Paulo State, Brazil. This is the first occurrence of gastropods in the analyzed region and to this geological unit where the paleontological content is mostly known by the big turtle bones and shells, and by other vertebrate remains. These finding attests the paleontological potential of Adamantina Formation to the study of invertebrate fossils, nearly neglected in the moment, and could help in the refinement of fl uviolacustrine paleoenvironmental and about the paleoecology during the time of Bauru Group depositon.
Key words: Mollusca, Gastropods, systematic, Adamantina Formation, Late Cretaceous, Brazil.Downloads
