Stygimoloch
The name of Stygimoloch itself is translated roughly from the Greek word ”horned demon from the demon hell”. This Stygimoloch possessed the boniest, biggest noggin of any pachycephalosaur, a thick-healed lizard. Assumingly, the male Stygimoloch head-butt each other and on some occasions, they rendered one another unconscious for them to mate with the lady Stygimoloch.
