Oviraptorosaur

Diet

A 2022 study of the bite forces of oviraptorosaurs such as Incisivosaurus, Khaan, Citipati, and Conchoraptor suggests that most if not all oviraptorosaurs had a very strong bite force. The moderate jaw gape seen in oviraptorosaurs is indicative of herbivory in the majority of the group, but it is clear they were likely feeding on much tougher or more types of vegetation than other herbivorous theropods in their environment, such as ornithomimosaurs and therizinosaurs were able to. The examinations suggest oviraptorosaurs may have been powerful-biting generalists or specialists that partook of niche partitioning both in body size and cranial function. One particular group, the Caenagnathidae, may have also been more omnivorous or even carnivorous than other oviraptorosaurs.
