A Bizarre New Species of Head-Butting Raptor

Xenovenator is a strange new thick-headed dinosaur from the Late Cretaceous of northern Mexico. It has a weird thickened and domed skull with fused and interlocking skull bones, adaptations seen in animals that use the head for combat. It seems to be a case of convergent evolution, a raptor that picked up features seen in the head-butting Pachycephalosauridae.
