Stygimoloch (Styx River Devil) is a dubious genus of pachycephalosaurid dinosaur that originated from Late Cretaceous North America. It has long been debated whether or not the genus represents or a distinct genus, or simply a growth stage of the larger Pachycephalosaurus.

Description[]

Stygimoloch was a plant-eating dinosaur that had bony spikes and knobs on its skull. This bipedal dinosaur lived about 68 million to 65 million years ago. Like other pachycephalosaurids, Stygimoloch was a Bipedal Herbivore with a moderately thick skull roof. It had long hind limbs and small forelimbs. Stygimoloch and other Pachycephalosaurs probably head-butted as a defense and in rivalry. 22% of all domes examined had Lesions suggesting osteomyelitis. This is an infection of the bone resulting from Trauma. So pachycephalosaurid domes were probably used in intra-species combat.
