migration was by a common ancestor of Stygimoloch, Stegoceras, Tylocephale, Prenocephale, and Pachycephalosaurus. The second event occurred before the middle...

Two traits also differentiate Foraminacephale from Sphaerotholus and Prenocephale: there are prominent grooves between the central lobe and the lateral...
