Naturally occurring pachycephalosaurus dinos are blue with small orange blotches and streaks. Their most distinguishing feature is the superhard cranial dome which they use to butt heads during mating rituals. Immediately in front of the dome and above their birdlike beak, are two sharp orange horns. These dinos are the original domeheads and the original buttheads!!

Below, we see a beautiful Dino-Diorama featuring a Pachyceplalosaurus family with their natural forest habitat showing in the background. Looks like the toddlers are either learning how to fish - or perhaps how to bathe in the cool blue waters of this beautiful spring waterfall! The purply berries and flowers that grow all around their home - hjelp camouflage the purple eggs and protect them from predators. 

All these dino-dioramas will eventually be housed in the Museum of Dinosaurs, Beasts and Chimera once the renovations there are complete.
