Stygimoloch is a putative genus of the pachycephalosaur family living in the early 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.

Wikipedia has a more detailed and comprehensive article on Stygimoloch

Jurassic World: Fallen KingdomEdit

It is revealed that there are surviving Stygimoloch populations on Isla Nublar, although they will now face an impending danger, alongside many other creatures, in the form of an erupting volcano.

Colin Trevorrow confirmed that the Stygimoloch will be in Jurassic World: Fallen Kingdom where an image shows where it is in a transport truck.[1] A Reddit post about the leaked plot revealed that it will be smaller than the Pachycephalosaurus, but designed to be more robust with a very thick neck. The coloring will be mostly reddish, with an orange underbelly, some black lightning marks on its back, and warm grey tones beneath, which the color is confirmed to be true by the image of it in the transport truck.[2]


Warpath: Jurassic ParkEdit

Stygimoloch is a playable dinosaur in Warpath: Jurassic Park that has low attack power which compensated with high speed. The Stygimoloch has 3 colors: orange, dark green, and yellow green.
