Sullivan's diagnosis for Pachycephalosauridae reads like one of those classic 'diagnoses' from the 1950's that lists symplesiomorphic or variable characters in addition to synapomorphies. "Ornithischian dinosaurs with thickened, fully-flat or incipiently to fully-domed frontoparietals." So... the thickening is all that needs to be mentioned then. "Supratemporal fenestrae absent to well-developed." Uh... this would exclude which states now?
It would seem to exclude exaggeratedly enlarged supratemporal fenestrae.
