Dracorex

Dracorex is a putative genus of pachycephalosaur from the Late Cretaceous Period. Its name means Dragon King, and its type species is Dracorex hogswartia, named after the Harry Potter Franchise's Hogwarts Academy.

Much like Stygimoloch, Dracorex had large, protruding spikes on the back of its head, with two large horns of three behind the head. It had bumps and a long muzzle, with spikes on its nasal area. Dracorex, like Homalocephale and Goyocephale, had a flat dome, which led to the theory that it and Stygimoloch were growth stages of Pachycephalosaurus or, if Stygimoloch is valid, a female Stygimoloch. However, the most profound, remarkable and unusual feature of Dracorex is a pair of large openings in the fenestrae, bigger in terms of front to back and wider in terms of side to side than in Homalocephale, and bigger than in Goyocephale. This fenestrae opening was present on ancient archosaurs and not in other pachycephalosaurs, thus leading to the fact that the temporal region of Dracorex is more primitive than any other pachycephalosaur. However, the earliest pachycephalosaurs were fully domed, so it could be likely that some early full-domed pachycephalosaurs evolved to have no domes and flat skulls, much like Dracorex. Additionally, the uncovered specimen showed signs of in the mid-cervical arch with the centrum, which leads to supporting evidence that Dracorex is its own genus.
