Sumario:Detailed analyses in species of fossil bivalve mollusks of the Bauru Group (Late Cretaceous, Bauru Basin), exposed in the Sérgio Mezzarila scientifi c collection (IG/ SMA/SP), expose the preservation of musculature scars that have not been described as yet to Anodontites in São Paulo and Minas Gerais state. These features, which are associated to taxa-external anatomies, contribute to better understand the life habits of these freshwater organisms that were probably related to seasonal energetic variations in the rivers, where these organisms lived. Despite the fragmentary character of this record, the new information broadens the paleoecological panorama of bivalves in the Late Cretaceous of the Bauru Basin.
