Pachycephalosaurus is the defining dinosaur for the group of dome heads known as "Pachycephalosaurus" , thick headed . Some domes were up to 7 inches thick . It was once thought that the dome was used to ram other males but if so both dinosaurs would have been in danger of breaking their necks of theropods . The dome would have been at the level of a tyrannosaur's knee.
