Pachycephalosaurus Skull

An extraordinarily rare skull of Pachysephalosaurus, the ‘thick-skulled lizard’, which lived around 65-68 million years ago in the late Cretaceous period of North America, alongside some of the most iconic dinosaurs such as Tyrannosaurus and Triceratops. It is known from only one species, P. wyomingensis, the adult forms of which are only known from skull remains.
