Goyocephale

Goyocephale

Like its close cousin, Wannanosaurus, Goyocephale is important because it's ancestral to the more evolved (and thicker-skulled) pachycephalosaurs of the late Cretaceous period, such as Stegoceras and Stygimoloch. This small, nimble herbivore had only rudimentary ornamentation on its head, and its relatively primitive skull had noticeable holes (the skulls of later pachycephalosaurs were solid masses of bone).

this dinosaur was seen once in jurassic park 2: lost world, but only for about 5 seconds. however it is in about ever one of the games.
