Dracorex hogwartsiamay 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.
History
The spectacular fossil skull ofDracorexwas discovered in South Dakota, USA, in 2004. This skull and some associated neck bones were described in 2006 as a new species of bone-headed dinosaur or pachycephalosaur. Robert Bakker, the lead author of the description, gave it a fantastic name:Dracorexmeans dragon king, whilehogwartsiarefers to Hogwarts Academy, the fictional school where Harry Potter trained.Dracorex hogwartsiais an appropriate name for a dinosaur with a spiny dragon-like appearance!
Some paleontologists think thatDracorexis really a juvenile of another bone-headed dinosaur,Pachycephalosaurus, from the same time and place. The year afterDracorexwas described, Jack Horner suggested that it looks different fromPachycephalosaurusbecause this species changed drastically as it grew up, developing a dome-like head as it matured. More fossil evidence will be required to determine ifDracorexis really a distinct species, or if it is just a growth stage of another dinosaur.
MaybeDracorexand other bone-headed dinosaurs used their bony skulls in head-butting fights. This is a controversial theory among paleontologists. Some cite strong neck bones in support of the idea, while others regard the bony skulls as too delicate for battle. WhetherDracorexused its spectacular spiny skull as a weapon, or just for show, takes nothing away from its striking appearance.
There is only one species ofDracorex,D. hogwartsia, known from a single skull and associated neck bones. This dragon-like dinosaur browsed for plants during the Late Cretaceous, at the end of the age of the dinosaurs, 66 million years ago.
