Ornatotholus browni (Wall & Galton, 1979) |
Ornatotholus is a genus of pachycephalosaur dinosaur from southern Alberta. It is the only putative "flat-headed" pachycephalosaur known from North America. It appears to share many similarities with Stegoceras, and may represent a juvenile form, making it a nomen dubium.
