Pachycephalosaurus eats small amounts from ground herbivore feeders.
They live in moderate social groups to survive predation and also prefer to have a variety of other dinosaurs nearby.
They like good sized open grassland areas with a slightly smaller coverage of forest.
They are vulnerable to most predators but can defend themselves against small carnivores.

Pachycephalosaurus was a pachycephalosaur (or thick-headed dinosaur) that lived in North America. It was one of the last non-avian dinosaurs before the Cretaceous-paleogene extinction event about 65 million years ago.
It is distinctive for the reinforced dome of its skull, leading to speculation that they used to fight each other by head-butting. This has more recently been countered with the suggestion of flank-butting.


Pachycephalosaurus fossils may have been discovered in 1850 in the Lance Formation in south-eastern Montana. Early finds were fragmentary, but more complete specimens have recently been discovered.


Pachycephalosaurus lived on what were floodplains. Its sharp separated teeth would have made it ideal for a mixed-plants diet, and capable of shredding leaves.
