Pachycephalosaurus wyomingensis (meaning "thick-headed lizard") is a genus of pachycephalosaurid dinosaur that lived at the late cretaceous period, 66 million years ago. Pachycephalosaurus means thick-headed lizard, because it had a bony dome on its skull. It used its skull for fighting donimants, hurting predators, and mating.
