Othnielia from Late Jurassic

Named after Othniel Charles Marsh, the famous palaeontologist.
Ornithopod, herbivore, up to 4 metres long and up to 20 kilograms
From the USA (Morrison Formation, Colorado, Wyoming, Utah)
Othnielia was a relatively large herbivorous biped, related to Leaellynasaura and Dryosaurus. So far, only a couple of well-preserved partial skeletons are known plus scattered bones and teeth. Othnielia used its horny beak to crop low-growing vegetation and its stiff tail acted as a counterbalance when running.
