Tyranasuarus rex

 I am learning about the t rex.

Tyrannosaurus rex was one of the most ferocious predators to ever walk the Earth. With a massive body, sharp teeth, and jaws so powerful they could crush a car, this famous carnivore dominated the forested river valleys in western North America during the late Cretaceous period, 68 million years ago.

Although T. rex is a household name, what we know about this tyrannosaur is constantly evolving. Improved technologies, such as biomechanical modeling and x-ray imaging, have allowed scientists to gain a deeper understanding of how this apex predator lived.

Strengths

Tyrannosaurus rex, whose name means “king of the tyrant lizards,” was built to rule. This dinosaur’s muscular body stretched as long as 40 feet—about the size of a school bus—from its snout to the tip of its powerful tail. Weighing up to eight tons, T. rex stomped headfirst across its territory on two strong legs. These dinosaurs likely preyed on living animals and scavenged carcasses—and sometimes they even ate one another.

The head of a T. Rex was the real stuff of nightmares. This fierce carnivore was optimally built for crunching through its meals, with a stiff skull that allowed it to channel all the force of its muscles into one bite—delivering up to six tons of pressure. This dinosaur used its 60 serrated teeth, each about eight inches long, to pierce and grip flesh, throwing prey into the air and swallowing it whole. To keep itself from overheating while crushing prey with its mighty jaws, the giant animal had vents in its head to help its brain stay cool, similar to those found in alligators.
