... is assigned to a new species of Stegoceras . Domes referable to Stegoceras sp. (Judith River and Hell Creek Formations) are the first conclusive evidence of the presence of this genus in the United States. A large dome from the Oldman Formation of Alberta is referred to Pachycephalosaurus ; this specimen...
