Description

DISCOUNT 50% - real fossil tooth of a biped thick skull roof dinosaur, mm 4.

Pachycephalosaurus (meaning "thick headed lizard") lived during the Late Cretaceous Period (Maastrichtian stage) of what is now North America. Remains have been excavated in Montana, South Dakota, and Wyoming. It was an herbivorous or omnivorous creature which is only known from a single skull and a few extremely thick skull roofs. This dinosaur is monotypic, meaning the type species, P. wyomingensis, is the only known species. Pachycephalosaurus was one of the last dinosaurs before the K–T extinction event.
Like other pachycephalosaurids, Pachycephalosaurus was a bipedal omnivore with an extremely thick skull roof. It possessed long hindlimbs and small forelimbs. Pachycephalosaurus is the largest known pachycephalosaur, measuring nearly 4.5–5 meters (15 –16 ft) in length and up to 2000 kilograms (4400 lb) in weight.
The thick skull domes of Pachycephalosaurus and related genera gave rise to the theory that pachycephalosaurs used their skulls in intraspecific combat. This theory has been discredited in recent years.
