Robot helps researchers see how 290M-year-old tetrapod walked

Complete skeletons, a matching set of fossilized footprints and a robot have helped researchers figure out that a 290 million-year-old tetrapod moved with an upright posture, much like that of a caiman. Researchers used data gleaned from the skeletons and footprints to create computer models of the tetrapod that evaluated hundreds of different gaits.
