"Specific items that invite disagreement include...the
removal of Yaverlindia (sic), a specimen found on the
Isle of Wight, from pachycephalosaurids"
I'm with you on this one, Simon. Also, don't forget (and I'm sure you
haven't) that _Majungatholus_ was also removed from the Pachycephalosauria,
into the Abelisauria. AFAIK, this has not "invited disagreement".
