Tyrannosaurus rex is easily one of the biggest beefiest bipedal animals to ever live. Because of this, it is a good example of how adaptations and constraints of the anatomical traits and functionality of those traits operate at body sizes of several tons. In the scientific literature, there has been a lot of talk about how fast T. rex and other large theropod dinosaurs could run, and this is a big part of how they lived and hunted as carnivores. But despite a century of research since Osborn's 1916 work on the anatomy of tyrannosaur limbs, there is still no agreement on T. rex's top speed or on whether or not its huge body size prevented it from running at all. Until a 2017 paper, that is.
