Tyrannosuchus

A massive 40+ foot rauisuchid. Brought back during the early Jurassic, it's one of the parks deadliest predators. It's full tame, Tyrannoschus Infernalis, translates to Tyrant Crocodile from Hell, and it lives up to the name. With bone shattering jaws, powerful legs, and a heavy tail, it has been shown to be able to not only withstand a Tarbosaurus bite, but break free and fight back. It's closest relative is Saurosuchus.
