The I-Rex isn't a regular dinosaur, it's a genetically engineered hybrid created from the DNA of other dinosaurs such as a T-Rex, a Velociraptor, a Giganotosaurus, a Carnotaurus, a Majungasaurus, a Rugops, and a Therizinosaurus as well as some modern animals such as a cuttlefish, a tree frog, and a snake.
