About Colepiocephale:

There's one thing you can say about the paleontologist who discovered Colepiocephale: he or she had a good sense of humor. In true Three Stooges style, this tiny herbivore's name is Greek for "knucklehead," as befits your typical pachycephalosaur (or bone-headed dinosaur).

Its odd name aside, Colepiocephale is important for being one of the earliest boneheads discovered to date in North America (Asian pachycephalosaurs, such as Goyocephale, appear to have predated their American cousins by a few million years). Colepiocephale also had an unusual skull compared to other dinosaurs of its kind; it wasn't domed or especially thick, but flat, sloped and roughly triangular.
