Pachycephalosaurus



Pachycephalosaurus was a medium-sized herbivorous dinosaur that lived in the late Cretaceous period, 89 to 75 million years ago, in North America. They are famous as "bone-head" dinosaurs, due to the 9-inch thick rounded plate of bone in their foreheads. Contrary to popular belief, Pachycephalosaurus did not butt heads with each other.

In Jurassic Park
Pachycephalosaurus was seen in The Lost World: Jurassic Park, ramming into hunters and equipment. They were, however, only half the size of real Pachycephalosaurs. A possible explanation was that these individuals were not fully grown.

In Operation Genesis
Pachycephalosaurus is a dinosaur in the game Jurassic Park: Operation Genesis as a two-star small herbivore, at closer to its correct length than those of the movie. It is the primary dinosaur that the player must create to endorse more new dinosaurs. It will fight against each other.
