Why borrow it into Latin and not just keep it Greek? After all I've hardly ever seen a genus name ending in -opsis.

There's actually quite a few genus names that end in 'opsis'. Just search for 'opsis' at:


And that's just the animals. Anybody involved in plant genetics knows of _Arabidopsis_.

There's at least one dinosaur that ends in 'opsis': the sauropod _Ornithopsis_.

Now if someone would get out there and name the genera *Ceratopsis*, *Protoceratopsis*, and *Leptoceratopsis*, on which the families Ceratopsidae, Protoceratopsidae, and Leptoceratopsidae could be based, we'd be in good shape.

_Ceratopsis_ is actually a pre-existing genus (a crustacean). Oh well. ;-)

_Ceratops_ (the nominative genus for Ceratopsidae) is probably an invalid genus (nomen dubium). Sereno (2005) is confident that _Ceratops montanus_ belongs to the Chasmosaurinae, based on the size of the horn cores. In fact, he is so confident that he renames this subfamily the Ceratopsinae. Let's hope that big brow horns are limited to chasmosaurines/ceratopsines among ceratopsians.
