You know, come to think of it, only a few names don't seem to be inspired by the name of the speices at all.
Off the top of my head, the name Ali doesn't seem to come from inspiration of Brontosaurus or Apatosaurus. Makes you wonder how the writers came up with that one.
We could also include Sierra and Rinkus. I doubt their names are inspired by any type of flyer whatsoever.
Same deal with Littlefoot. Doesn't seem to be inspired by the name of species at all.
I'm sure there are at least a few others, but I can't think of them right now.

Anyways, Titanosaur, in the end, it's your call. :^.^:
