Alaskacephale

What it was like

Alaskacephale was a bone-headed dinosaur, a two-legged plant eater with a thick, domed skull. It is known from a single bone from the back of the skull, covered in bony knobs.

Its world

It lived about 72 to 66 million years ago, at the end of the Late Cretaceous, in what is now northern Alaska. The region lay far north even then, with dark winters. Its bones come from the Prince Creek Formation, where it shared the land with the horned Pachyrhinosaurus, the duckbill Edmontosaurus and the small tyrannosaur Nanuqsaurus.

How it was found

Sullivan named Alaskacephale in 2006 from one find. It is one of the few bone-headed dinosaurs known from the far north.
