Abstract

Body imprints and tracks attributed to large crocodylians from the Lower Cretaceous Sousa Formation of Brazil are described and interpreted as having been produced in a subaqueous environment. In addition to the crocodylian tracks, the assemblage also comprises isolated tracks from medium-sized theropods. The studied crocodylian traces are interpreted as subaqueous traces possibly produced by Mesoeucrocodylia crocodyles, during half-swimming and resting next to the margin of a lake. This is the first record of crocodylian traces in Brazil and confirms the potential for finds of new ichnosites in the Rio do Peixe basins of northeastern Brazil.
