The spectacular fossil skull of Dracorex was discovered in South Dakota, USA, in 2004. Dr. Robert T. Bakker, the lead author of the description and curator of the Houston Museum of Natural Science Paleontology Hall, gave it a fantastic name: Dracorex means ‘dragon king’, while hogwartsia refers to Hogwarts Academy, the fictional school where Harry Potter trained. Some paleontologists think that Dracorex is really a juvenile of another bone-headed dinosaur, Pachycephalosaurus, from the same time and place.

Dracorex was a plant-eating dinosaur known only from a fossilised skull and neck. The complete animal may have been up to 10 feet long. Its fearsome-looking bony skull was covered in bumps, spikes, and spines, reminiscent of a fictional dragon, as shown on our Dracorex toy. It had a narrow snout and, like other ‘bone-headed dinosaurs’, it probably walked on two long back legs and had short arms with five-fingered hands. Its claws were probably blunt and hoof-like.
