Cranial functional specialisation for strength precedes morphological evolution in Oviraptorosauria
Abstract Oviraptorosaurians were a theropod dinosaur group that reached high diversity in the Late Cretaceous.Within oviraptorosaurians, the later diverging oviraptorids evolved distinctive crania which were extensively pneumatised, short and tall, and had a robust toothless Wine Cooler beak, interpreted as providing a powerful bite for their herbi
