Minor correction: the type *species* of that genus must be used as a
specifier. Or the type specimen of the type species. So any name based
on "Ceratops" (not just the ICZN names--"Ceratopsoidea",
"Ceratopsidae", "Ceratopsinae", "Ceratopsini", "Ceratopsina"--but
others like "Ceratopsia" and "Ceratopsomorpha") must include either
Ceratops montanus Marsh 1888 or USNM 2411 as an internal specifier.
