Pentaceratops

Pentaceratops was a rhinoceros-like dinosaur. It walked on four sturdy legs and had three horns on its face along with a large bony plate projecting from the back of its skull (a frill). One upward-pointing horn above its parrot-like beak and two longer, forward-pointing horns above its eyes probably provided protection from predators, and were possibly used in mating rivalry and rituals. It also had two enlarged, horn-like cheekbones that protruded from its face. It had a very large skull, 9.8 feet long, with a very large, bony, scalloped, head frill. It has the largest-known skull ever found for a land-dwelling animal.
