“This is the Stygimoloch, and it is one of hard-headed dinosaur. It has an armored dome crowed by horns. Despite this, it’s social and a relatively docile animal… unless threatened. Then, steer well clear of it. This dinosaur can do a number on its enclosures, and bash its way through any number of obstacles. Take that into consideration when you’re planning its environment.”
Isaac Clement

Stygimoloch (“demon from the river Styx”) is a dubious genus of the pachycephalosaur family living in the Late Cretaceous period. It was distinguished from other pachycephalosaurs by the row of spikes on the back of its head, behind the dome characteristic of the family. Jack Horner has presented evidence in 2009 (and others after him) that suggests that Stygimoloch might be the juvenile form of Pachycephalosaurus.
