I created this Pachycephalosaurus from the large version of the Jurassic Park II Pachy. and the Jurassic Park Utahraptor (both made by Kenner).

The head, feet and arms of the Pachycephalosaurus were grafted onto the Utahraptor body. Cuts made in the legs allowed a more dynamic position, which was cemented with wire and Quikplastic.

Pachycephalosaurus wyomingensis

Pronounced: Pack-e-Sef-ah-low-Saw-rus Diet: Omnivore (Meat & Plant-Eater) Name Means: "Thick Head Lizard" Length: 26 feet (8 m) Height: 8 feet (3.5 m) Weight: 1 ton (900 kilos) Time: Cretaceous

This was a real bonehead. The skull of Pachycephalosaurus was 8 inches thick on top. For years, scientists thought it was used primarily for head-butting contests, sort of like mountain goats do today, but recent studies of the skeletons of related dinosaurs show that its neck might have broken if it tried that.

(My note: Despite this research, it seems obvious to anyone with a brain larger than a walnut that the head was obviously used for head butting with members of its own species. Just as obviously, if you line up two of these critters and bang 'em fast enough, eventually you'll reach the point where the neck WILL break. However, you don't need to be a brain surgeon to figure out that the animals did this in ritualistic fashion, a controlled contest, rather than trying to kill each other, as is seen in every species that butts heads today.
