Pachycephalosaurus, known for its thick skull, roamed the earth during the late Cretaceous period. Despite its armored dome, it was herbivorous and not much of a threat to other dinosaurs. Its name means “thick-headed lizard” in Greek, and it is believed that males used their skulls to compete for mates or resources. Though not the flashiest dinosaur, Pachycephalosaurus was certainly unique in its appearance and behavior.
