The earliest-known animal that walked on two legs November 2000 |
Eudibamus cursoris was a small, fast-moving lizard that lived during the Permian period, roughly 290 million years ago. It is the earliest-known animal that walked on two legs (it was facultatively bipedal; it ran on two legs when it needed to).
Speed: David Berman (of the Carnegie Museum of Natural History) estimated that Eudibamus could run about 15 miles per hour (24 kph). This plant-eater likely used its speed to avoid its predators.
Fossils and Name: Fossils of this synapsid were found in a quarry near Gotha, Germany, in 1993. Eudibamus was named by Robert Reisz, et al. Eudibamus was not a dinosaur, but another, much earlier type of reptile. Dimetrodon was a contemporary of Eudibamus.
Classification: Class Reptilia (reptiles), order Eosuchia, suborder Bolosaurida, family Bolosauridae, Genus Eudibamus, species E. cursoris.
