Polyphyly or paraphyly doesn't matter. If the group is at the family level, 
and it contains the type genus Ceratops, then its name must be Ceratopi[put 
your favorite ending here]. The only way to change this rule is to get rid of 
the Linnaean concepts of family and family level, and of type genus.
