Pachycephalosaurus was a bipedal herbivorous dinosaur which is best known for its odd, dome-shaped growth on top of its head. Scientists have not yet come to an agreement on what their hard heads were used for; some think they may have used them to ram others of their species, while others think it was for display to impress potential mates. Others yet think their noggins were used for a combination of the two.
