Dracorex

Dracorex hogwartsia may have looked like a fearsome dragon, but it was actually a gentle plant-eating dinosaur. This spiny bone-headed dinosaur was named after Hogwarts, the fictional academy attended by Harry Potter. The fossil remains of this fantastic beast were found in South Dakota, USA. It lived in the Late Cretaceous, 66 million year ago, at the end of the age of the dinosaurs.
