Pachycephalosaurus (meaning "thick headed lizard"), was the last, largest, and most famous member of the thick-headed dinosaurs. It existed during the Late Cretaceous period in what is now North America.



Pachycephalosaurus was created by InGen inside their compound on Isla Sorna where they were taken care of by the workers there at a young age.

Their skin was dark brown with dark blue markings.

It was not planned for InGen's Jurassic Park on Isla Nublar.


The Lost World: Jurassic ParkEdit


"Friar Tuck"

The InGen Hunters captured a Pachycephalosaurus on the Game Trail. It was nicknamed "Friar Tuck" because their leader Roland Tembo was unable to pronounce its genus name. This individual was later freed by Gatherers Dr. Sarah Harding and Nick Van Owen, though it is unknown if it survived.

Jurassic WorldEdit

A new set of clones was created by InGen for Masrani Global Corporation's Jurassic World. These new clones were close to the size of the originals. The new clones' skin was dark red with lime spots and a lime underbelly. They resided in the self-titled Pachy Arena where visitors could watch them have on of their famous head-butt duels. Everytime they butt heads, their inplants became temporarily disabled, which allowed the Pachycephlosaurs to escape the Pachy Arena without being tracked.

Before the 2015 Isla Nublar Incident, a Pachycephalosaurus broke out of the Pachy Arena but was tranquilized and returned to the paddock by some Asset Containment Unit workers.
