The list of confirmed prehistoric creatures being added is here. Keep in mind though that the devs have a secret list of upcoming mobs, aswell. I can tell you though that Utahraptor will not be added to the mod and dinosaurs like Dracorex will probally not be added because of how similar they are to a mob already in the game (not limited to Dracorex). Good list of prehistoric animals, though. A good place to put creature suggestions is on the New New Prehistoric Creature Suggestions Thread. And to answer your original  question, Carnotaurus, I am 99% sure, will be added in the Paleontology or Dimension Update, which releases sometime in the future on no specified date. But like I said, that's an awesome list!
