As long as it had some unique behaviors it would be fine.I’m really doubtful about Saurophaganax. Why? Because the wiki already talked about the game’s Allosaurus already being that size and the possibility of Sauro being another Allo species. The only way I see is to make Allo smaller, bluer, and spikier like in Big Rock as well as “nerf” him a little bit (I want Old T to be the strongest carnivore behind the Indos). Other than that, it’s a lost cause.
