This plant eater was bipedal (walked on two legs). It had thin legs and a stiffened tail that gave it speed and agility. It had five-fingered hands and four-toed feet, all clawed. It had large eyes and short arms. Nanosaurus resembled Hypsilophodon. Its fossils (two partial skeletons and teeth) were found in Colorado and Utah in rocks of the Late Jurassic age.
