What is pachycephalosaurus eat?

Pachycephalosaurus was a herbivorous dinosaur that lived during the Late Cretaceous period, about 70-65 million years ago. It is believed to have primarily fed on plants such as ferns, cycads, conifers, and flowering plants. The sharp and serrated teeth of the Pachycephalosaurus suggest that it may have also fed on tough and fibrous plant material. It is thought that Pachycephalosaurus was able to grind up its tough plant food using its powerful jaw muscles and its battery of teeth. Because it was a relatively large dinosaur, it probably needed to consume a large amount of plant material each day to sustain its energy needs.
