Re: A critique of Sullivan's pachycephalosaur paper,

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
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.
Why can't you be a non-conformist just like everybody else?
