Re: Avaceratops and Ceratops (was Re: THE NEW ISH OF JVP)

If you're going to include Ceratops in the subfamily Chasmosaurinae, then

IF, yes. Unless new material has surfaced, there's no good evidence that
_Ceratops_ is indeed in the subfamily as _Chasmosaurus_ and _Torosaurus_.
Indeed the _Avaceratops_ paper in the last issue strongly implies it's not.
The rule is that, if a family is subdivided into subfamilies, tribes, etc.,
any subdivision that contains the type genus must have the same name as the
family, with the appropriate change in ending.
Interestingly, if _Ceratops_ is neither a chasmosaurine nor a centrosaurine,
then it may be removed from the Ceratopsidae altogether (like Wolf and
Kirkland did with _Zuniceratops_). Now, that would really screw things
