being found in the morrison and tendaguru put the family ceratosauridae in the presence of other large predators. in north america, it is likely that members of the family such as "c. nasicornis" competed with allosaurs ("a. fragilis") for food, such as sauropods common to the region at the time. in africa and europe members also competed with other large predators for similar food sources. the presence of "c. nasicornis" at the cleveland-lloyd dinosaur quarry along with the remains of several allosaurids is a good indication of just how close members of this family and other predators coexisted.
