Titanosauridae is slowly being pushed out in favor of Saltasauridae.
Regarding Ceratopidae, the next available non-nomen dubium available
family-level names are Chasmosauridae (ex Chasmosaurinae Lambe, 1915) and
Centrosauridae (ex Centrosaurinae Lambe, 1915), both of which appear in the
same document so neither has priority (revisor's choice). And for
Hadrosauridae it might be Claosauridae Marsh, 1890 unless too many people
think Claosaurus is a nomen dubium (as with Hadrosaurus, poor or no skull
material). After that it's Saurolophidae (ex Saurolophinae Brown, 1914).
