Tyrannosaurus Rex, commonly called T. Rex or T-Rex, was one of the most fearsome predators of the Late Cretaceous, around 65 million years ago. Known as “The King of Tyrant Lizards,” this giant theropod dominated its ecosystem as an apex predator. T. Rex could reach lengths of up to 12–13 meters and weigh approximately 8–10 tonnes, with an enormous skull lined with sharp, serrated teeth capable of crushing bone.

Fossil evidence suggests T. Rex had strong hind limbs, a long, muscular tail for balance, and exceptionally powerful jaws, giving it the strongest bite force of any land animal known. Its forelimbs were short but heavily muscled, each ending in two clawed fingers, likely used to grasp prey. T. Rex’s hunting strategies and physical adaptations make it an iconic model for studying predator-prey dynamics and Late Cretaceous ecosystems.
