Styracosaurus

Styracosaurus was a medium-sized Ceratopsian that lived in the Late Cretaceous of North America. It had many sharp spikes along it's frill, and a horn on it's nose. There is some doubt about the effectiveness of the horns on the frill for defense. As they extended back over the neck, they certainly would have afforded some protection against predators and would have looked formidably threatening when viewed from the front, but as they stuck out to the side, they would have been difficult to employ as stabbing weapons. It is possible that the elaborate horned frill, which would have been covered with skin, served more as an accoutrement for courtship display than as a weapon of defense.

In the game Jurassic Park: Explorer the following information is given about this creature:

''Styracosaurus traveled in herds and cared for its young after they hatched. Evidence for comes from a  in  where fossils from over one hundred Styracosaurus individuals were discoved.''
