Abstract

The Marilia Formation (Baum Group, Baum Basin) is an important record of the Upper Cretaceous in Brazil, and hosts an important fossil content. However, works regarding continental ichnology in this unit are still scarce. In order to improve this knowledge, the present work describes the occurrence of Camborygma litonomos in paleosols developed from floodplain deposits of the Marilia Formation in the Minas Gerais State. This trace fossil is associated with the activity of freshwater crayfishes, digging the soil looking for protection and to avoid the carapace dryness. Crayfish body fossils have not yet been described in deposits of the Bauru Group, thus, the trace fossil here recorded is the exclusive evidence of this organism, which is of great importance to the knowledge of the invertebrates paleodiversity of the Marilia Formation during the Late Cretaceous.
