T. rex Biomechanics
T. rex is often depicted with its great legs in a crouch—but was that its typical pose? Some biomechanical scientists doubt it. This model, shown mid-stride in this scale model, may have been rather straight-legged, too. An accompanying video shows how biomechanics experts think a creature the size of T. rex might have gotten around, and a how this great carnivore was likely much slower than any Hollywood T. rex.
