The Sphaerotholus, identified as Pachycephalosaurus in the show, was a herbivorous dinosaur that lived 70 to 65 million years ago.
The Sphaerotholus is a plant-eating dinosaur, but there's some scientists that believe that it was also an omnivore.
The Sphaerotholus probably attracts its mates with bright colors on its body. However there is evidence, albeit disputed, to suggest that intraspecific combat did occur as well, with males butting heads with each other
Episodes featured Edit
The Sphaerotholus is featured in the episode "End Game". A young Sphaerotholus is chased by two baby Tyrannosaurus rex before Jack the T. rex eats them. Another young Sphaerotholus was being chased by a pair of Troodon. To escape, the dinosaur hides under a Ankylosaurus, but the Troodon follow it. However, the Ankylosaurus sits on one of the Troodon and the Sphaerotholus escapes. After the meteor strikes, the skull of the Sphaerotholus was found by the Troodon.
The Sphaerotholus, shown in the episode "End Game", uses the same model of the Prenocephale, a creature intended to appear on Dinosaur Revolution, however it was ultimately cut. This may be intentional, as Sphaerotholus has be suggested to be synonymous with Prenocephale.
