Stygimoloch 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.
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.
It is smaller than the Pachycephalosaurus, but is more robust with a very thick neck. It has pronated wrists with claws on all five digits. The coloring is mostly reddish, with an creamy underbelly, some black lightning marks on its back and head, a white dome, dark grey spikes, a dark grey streak around its dome, dark grey and dark brown patterning all over the body.
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.
It is no. 090 of the Herbivore Ones that can be created in Jurassic Park III: Park Builder.
Stygimoloch has been confirmed to appear in Jurassic World: Alive, based on the film version of the dinosaur.
A new figure of Stygimoloch will be released as part of the toy-line for Jurassic World: Fallen Kingdom. Stygimoloch will also be in the LEGO JW:FK toyline.
- The inclusion of Stygimoloch in Jurassic World: Fallen Kingdom was directly challenged by Jack Horner, as he had proposed the initial theory that it was a juvenile Pachycephalosaurus. Despite this, Stygimoloch was kept in.
