So Tyrannosaurus, Velociraptor, Tree Frog, Snake, Cuttlefish, and Therizinosaurus are confirmed, with Giganotosaurus, Rugops, Majungasaurus, and Carnotaurus up to debate.

My opinion on those 4 Dinosaurs is that at least one of them was used, but possibly not all four. Chances are they put one in, and decided it looked enough like a mix of the four of them that they could get away with it.
