Comments: This specimen also includes extensive juvenile Pachycephalosaurus or Dracorex cranial material recovered from the same site. This extremely rare material is scientifically significant, and can be used to actually test claims about pachycephalosaur ontogeny. The scientific publication of this specimen would be the first official osteology of the post-cranial skeleton of Pachycephalosaurus. Its scientific importance is unquestioned.
