Roleplay as a T-Rex, the king of the dinosaurs, live, mate, hunt, make a pack, and have a family. Tyrannosaurus Rex means "King of The Tyrant Reptiles". Don't believe Jurassic Park 3, because T-Rex would win in a real battle. That is because spinosaurus' teeth was only made for fish and small Dinosaurs, T-Rex's was made for small, medium, and Large Dinosaurs.
