Tyrannosaurus rex, whose name means “ king of the tyrant lizards,” was built to rule. Improved technologies, such as biomechanical modeling and x-ray imaging, have allowed scientists to gain a deeper understanding of how this apex predator lived. rex is a household name, what we know about this tyrannosaur is constantly evolving.
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.Īlthough T.
