Okay, so your last statement means that _P. lacustris_ still remains a
valid taxon.  Some years ago, there was speculation (only on this mailing
list, as far as I can determine), that the Hell Creek Fm. _P. lacustris_
teeth might be the dentary fangs of homalocephalid pachycephalosaurs.  I
take it that this hypothesis is unlikely, now?
