Pachycephalosaurus was a plant-eating dinosaur, but also was well built for battle. This creature had a crown of solid bone that was surrounded by spikes on both sides of its head. Head-butting brawls broke out between rival males in a herd; when danger was near, this dinosaur could deliver a lethal blow to predators but probably preferred to run. that's the ones from the land before time and Jurassic Park, They live in The Late Cretaceous Period and They Are Found in Northern USA and Canada And They Are Borned in 1943.
Like other pachycephalosaurids, Pachycephalosaurus was a bipedal herbivore, possessing long, strong legs and somewhat small arms with five-fingered hands. Pachycephalosaurus is the largest-known pachycephalosaur, known for having an extremely thick, slightly domed skull roof; visually, the structure of the skull suggests a "battering ram" function in life, evolved for use as a defensive mechanism or intra-species combat, similar to what is seen with today's bighorn sheep or muskoxen (with male animals routinely charging and head-butting each other for dominance). This hypothesis has been disputed in recent years.
Pachycephalosaurus was among the last species of non-avian dinosaurs on Earth before the Cretaceous–Paleogene extinction event. The genus Tylosteus has been synonymized with Pachycephalosaurus, as have the genera Stygimoloch and Dracorex, in recent studies.
