Dinosaurs never evolved bipedal locomotion, they evolved from older, bipedal animals and later some of them reverted to quadrupedal locomotion.

- mcv 6y agoInteresting. With most land-based animals being four-legged today, it's tempting to assume that that would always have been the advantage over two-leggednes, with the exception of a few specialised long-distance runners (us, ostriches and kangaroos, basically). But maybe it's today's animal shapes that are the exception.
