You’ve seen the dinos in Dinosphere– but have you ever taken the time to really get to know them? Well now’s your chance! In the Meet the Dinos blog series, you learn the behind the scenes story on all of your favorite dinosaurs, from their lives in the cretaceous period to their discoveries!

Who is Dracorex?

Dracorex hogwartsia is a dinosaur that is new to science, and it bears a close resemblance to a fairy-tale dragon, with its bony head covered in spikes and knobs.



Dracorex belongs to the group of ornithischian dinosaurs called Pachycephalosaurs, or bone-headed dinosaurs. These dinosaurs were a group of plant-eating dinosaurs that are largely characterized by their distinct dome-headed skull. The group actually consists of both flat-headed forms and highly domed forms. They lived in both Asia and North America during the late Cretaceous Period, 95 to 65 million years ago.

Dracorex is a unique addition to the paleontological record. Until now, no flat-headed Pachycephalosaur fossils have been discovered in North America. Further, no flat-headed dinosaurs with this unique configuration of knobs and spikes have ever been found. This new specimen suggests a significant new branch in the evolutionary development of the Pachycephalosaur family—much more complicated than paleontologists suspected.



“The discovery of this new flat-headed Pachycephalosaur was a total paleontological surprise,” said internationally-recognized paleontologist Dr. Robert Bakker. He added, “Dracorex is a scientifically significant milestone in the world of paleontology; it proves that family trees were still branching off and evolving, even near the end of the age of dinosaurs. It demonstrated a world of color and movement in nature more recently than we ever thought possible.”



In a recent publication, scientists were able to closely describe this new species. “It is truly a magnificent specimen. You hardly ever find skulls of these dinosaurs in such a complete state,” said Dr. Robert Sullivan, the vertebrate paleontologist and senior curator at the State Museum of Pennsylvania. “This spectacular skull shows an amazing combination of primitive and advanced features. Its discovery has dramatically altered our view on the relationships of these strange pachycephalosaurid dinosaurs to other dinosaurs,” Sullivan added.



How do you name and completely new species of dinosaur?



A team of museum scientists officially named the new dinosaur species Dracorex hogwartsia, the “Dragon King of Hogwarts. The name celebrates Hogwarts School for Witchcraft & Wizardry, the academy for wizards in the Harry Potter novels.



“All of us dinosaur-hunters agree—it’s splendidly appropriate!” said Dr. Bakker, curator at the Houston Museum of Natural Science and a long-time friend of The Children’s Museum of Indianapolis. “Dinosaurs are wonderful for getting kids to explore with their minds and exercise their scientific imagination. And that’s where Ms. Rowling excels too. Her books invite the reader to probe mysteries, solve riddles and learn the craft of fighting ignorance and evil,” Bakker added.



When hearing of this honor, J.K. Rowling stated: "The naming of Dracorex hogwartsia is easily the most unexpected honor to have come my way since the publication of the Harry Potter books! I am absolutely thrilled to think that Hogwarts has made a small claw mark upon the fascinating world of dinosaurs. I happen to know more on the subject of paleontology than many might credit, because my eldest daughter was Utahraptor-obsessed, and I am now living with a passionate Tyrannosaurus rex-lover, aged three. My credibility has soared within my science-loving family, and I am very much looking forward to reading Dr. Bakker and his colleague’s paper describing “my” dinosaur, which I can’t help visualizing as a slightly less pyromaniac Hungarian Horntail.”



The discovery and preparation of a one-of-a-kind fossil

The dinosaur was discovered by Brian Buckmeier and brothers Steve and Pat Saulsbury, all from Sioux City, Iowa. They found the remains of Dracorex during a fossil collecting trip in the Hell Creek Formation of central South Dakota. It was Steve Saulsbury who first suggested that they donate their new find. Steve fondly recalled taking his daughter Alexandra to the museum when he and his family lived in Indianapolis during his residency at Indiana University Hospital in the early 1990s. Steve talked to the others, and they soon agreed the museum would be the perfect home for this specimen. The trio donated their discovery to the museum in late 2004.

When Dracorex came to the museum it was still in the plaster field jacket.

Vertebrate paleontologist Victor Porter, along with preparator Shane Ziemmer, spent many hours getting this skull ready for exhibit. As the skull was cleaned and pieces glued together, thousands of children passed by the laboratory windows watching.
