Dracorex is a dinosaur from the Late Cretaceous of North America. Scientists have only recovered a skull and a few vertebrae in South Dakota’s Hell Creek Formation. “Dracorex hogwartsia,” meaning “dragon king of Hogwarts,” belongs to the larger group of herbivorous or omnivorous “Pachycephalosauridae,” known for their thickened, domed skulls. Experts debate about the reason for such ornate skulls; one theory is that they head-butted each other during mating rituals. How romantic!
