George Olshevsky ("A Revision of the Parainfraclass Archosauria Cope,
1869, Excluding the Advanced Crocodylia," _Mesozoic Meanderings #2_, 1991,
page 99) postulates that the heterodontosaurids may have given rise to the
Pachycephalosauria. 

But, then, I confess I have a certain personal fondness for
_Heterodontosaurus tucki_.
