Titanosauridae has already been dumped. Ceratopsidae should be dumped.
Using your logic, Deinodontidae should be used instead of
Tyrannosauridae, because the former has priority (it was named first).
But we don't, because _Deinodon_ is a nomen dubium.
There's no point naming a family-level clade after a genus, unless
you're going to include that genus in the phylogenetic definition of
that clade. Otherwise, you can't be sure if the nominative genus
actually belongs inside the clade.
I hope Mickey Mortimer had a good night's sleep.... ;-)
