The Tyrannosaurus Rex is probably one of the most dangerous theropod dinosaurs during the late Cretaceous period. This bipedal carnivore had a massive skull with dozens of sharp teeth, and strong hind legs to chase down its prey. Though its forelimbs are small, they are unusually powerful and have two clawed digits each. Dubbed as the “King” of the dinosaurs, this creature was the largest living carnivore ever to walk the earth.

The largest trex skull measured up to 1.5 meters in length. It was extremely wide in the rear but had a narrow snout, allowing really good binocular vision. The skull bones were massive, and some nasal and other small bones were fused together. Many contained a “honeycomb” of tiny air spaces that may have made the bones more flexible and lighter. The tip of the upper jaw is U-shaped, allowing the dinosaur to rip out as much bone and tissue as it can.
