Easier said than done, Mike. :-)
I still don't understand why all this effort is preferable to simply abandoning
the name (Ceratopsidae) altogether. Like I said previously: it's a lost cause.

Exactly. So we might as well get used to the idea of a world without
Ceratopsidae. We'll still have Ceratopsia and Neoceratopsia and maybe
Ceratopsomorpha, though. So it ain't all bad. (Although Ceratopsoidea might
have to go.)

Centrosauridae and Chasmosauridae are both available, although I'm not sure
which one would have priority. Both names are attributable to Lambe (1915),
when he erected the respective subfamilies.
