How fast can a Pachycephalosaurus run?
They based the models on photographs and reconstructions of the skulls. They simulated the animals moving with closing speeds of both 6.7 mph and 15 mph (3 meters per second and 6.7 m/s), the latter being the maximum ramming speed given the likely hip heights and limb proportions of pachycephalosaurs.
Which dinosaur had the hardest head?
Pachycephalosaurus is the largest known dome-skulled, or bone-headed, dinosaur. These dinosaurs had extremely thick skulls, and they formed the group known as the pachycephalosaurs. Very few fossils have been found, but they include a complete skull of Pachycephalosaurus.
What did Pachycephalosaurus eat?
Diet du jour Maybe Pachycephalosaurus filled a general omnivore role, suggests Brusatte, “eating bushes and ferns, but also some small mammals, frogs, salamanders, lizards, and maybe even small dinosaurs.”
How long did the Pachycephalosaurus live?
Pachycephalosaurus lived from about 70 to 65 million years ago (Cretaceous) in the Mesozoic era. It was among the last of the dinosaurs to evolve. Like all other dinosaurs that lived at the same time as it, it became extinct about 65 million years ago because of an unknown cause.
How did the Pachycephalosaurus live?
Pachycephalosaurus was a herbivore. It lived in the Cretaceous period and inhabited North America. Its fossils have been found in places such as South Dakota, Colorado and Montana. Pachycephalosaurus is a bipedal ornithischian, most recognizable for the bowl-like crown that tops its ultra-thick skull.

Pachycephalosaurus heads only reached total lengths of two feet or so. In case you’re curious, human men and women have an average skull thickness of 6.5 and 7.1 millimeters, respectively. 2. Pachycephalosaurus Heads Were Once Mistaken for Dinosaur Kneecaps.
Pachycephalosaurus also had unusual teeth. The teeth were very small and ridged, and not particularly well suited to chewing fibrous plant material. It is therefore thought that Pachycephalosaurus ate leaves, fruit, seeds, and perhaps insects.
Are Pachycephalosaurus and Dracorex the same thing?
Dr. John R. “Jack” Horner—who, among other accomplishments, served as the Jurassic Park trilogy’s dino consultant—maintains that Pachycephalosaurus and two similar creatures which shared its habitat were really the same animal. Stygimoloch and Dracorex are smaller and had much flatter skulls.
