Prestosuchus is a legendary amphibian that can be created in the game, even though in real life it was a terristrial reptile. It can only be obtained by joining a VIP Membership. When Prestosuchus is in its pen, its tail rests on the ground. While other crocodiles did this, it is unlikely Prestosuchus did this. With the legs under its hips like a dinosaur and unlike a semi aquatic crocodile, Prestosuchus' tail had to be above the ground for balance.
