About Nodocephalosaurus
What it was like
Nodocephalosaurus was an ankylosaur, an armored plant eater with a tail club. Its skull was covered in rounded, bumpy knobs of bone, which gave it its name.
Its world
It lived in the Late Cretaceous in what is now New Mexico, in the United States. Its bones come from the Kirtland Formation, where it shared the land with the horned Pentaceratops, the crested Parasaurolophus and the tyrannosaur Bistahieversor.
How it was found
Sullivan named Nodocephalosaurus in 1999 from a partial skull.
