15 feet long
Late Cretaceous, 65 million years ago
Western North America

Pachycephalosaurus was the largest of the dome-headed dinosaurs. They probably used their thick skulls to butt each other as rams do today with their horns. This dinosaur’s name means “thick-headed” reptile. Pretty accurate for an animal with forehead as thick as a bowling ball.
