Pachycephalosaurus: History, History of discovery & Paleobiology

Pachycephalosaurus (/ˌpækɪˌsɛfələˈsɔːrəs/) is a genus of pachycephalosaurid ornithischian dinosaur. The type species, P. wyomingensis, is the only known definitive species. The possibly synonymous taxon, Stygimoloch, might represent a distinct genus or a second species, P. spinifer. It lived during the Maastrichtian age of the Late Cretaceous period in…
