Tyrannosaurus rex is a huge, 40-foot (12 meter) long theropod dinosaur that lived in North America during the Maastrichtian age of the Late Cretaceous period, roughly 66 million years ago. As a carnivore, it had the strongest bite of any land animal, living or extinct, at a force of over 6 tons, combined with robust, serrated teeth, perfect for mutilating prey such as ceratopsians and hadrosaurs. Even though the arms of T. rex may seem small, it likely used them for grasping or clawing at its prey at close range. Contrary to the concept of its vision based on movement, as shown in Jurassic Park/World, it had such incredible eyesight at 13 times better than a human's, capable of seeing over 4 miles away. *PLEASE CREDIT ME IF USED*
