Pachycephalosaurus is a plant-eating dinosaur that lived approximately 75 million years ago during the Late Cretaceous Period. 

Pachycephalosaurus is believed to have grown to be about 15 feet long and probably weighed in excess of 900 pounds. This dinosaur is known for its five-fingered claws, long powerful legs, and three-toed clawed feet. However, it is most known for its thick domed skull. This dinosaur’s skull wall could be as much as ten inches thick. This thick skull plate was also surrounded by bony knobs. Paleontologists believe that this skull plate was used by the dinosaurs either as a self-defense mechanism or to butt heads with other Pachycephalosaurus dinosaurs, kind of like what big-horned sheep do. However, some paleontologists believe that this couldn’t have been the case. They posit that these dinosaur’s skulls were not heavy enough to absorb such impacts and that there haven’t been any fossil specimens of this dinosaur that have been found with the skull damage that would likely happen during such impacts.

It is believed that this dinosaur was an herbivore and lived primarily off of plants, fruits, and seeds. It is believed that its teeth were incapable of handling some of the tougher foliage like other herbivores of the era, so paleontologists believe that the plants it must have lived off of must have been soft. However, an interesting fact is that it is also possible that this dinosaur lived off of insects as well.
