Cerrejonisuchus is a genus of drysosaurid crocodile that is only represented by partial remains. These remains reveal however that Cerrejonisuchus had one of the shortest snouts of all of the known dryosaurids as well as the shortest body. Hailing from the Cerrejón Formation, Cerrejonisuchus was probably a predator of fish and possible small mammals. Cerrejonisuchus however may have occasionally been prey to massive predators such as the monster snake Titanoboa. Other animals from the Cerrejón Formation include the crocodiles Acherontisuchus and Anthracosuchus and the large turtles Carbonemys and Puentemys, as well as large three meter long lungfish.
