Stygimoloch/Jurassic World: Fallen Kingdom

It is revealed that there were surviving Stygimoloch populations on Isla Nublar, although they faced the 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. They were slightly oversized, the head is really big compared to the body size, the spikes are slightly different in arrangement, has a goat-like pupil which is unlikely, the torso is too short, has a much larger dome on its head, the tail is too flexible, and 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.

At least five Stygimoloch were rescued from Isla Nublar, including an individual named Stiggy, who inadvertently freed Owen Grady and Claire Dearing from their cells in Lockwood Manor and disrupt the auction, thus preventing more dinosaurs from being sold off before running off into the forest. The other Stygimoloch were eventually freed by Claire and Maisie Lockwood and escape the Manor alongside all of the other dinosaurs.
