Dryosaurus was a herbivore that lived in the Jurassic period and inhabited North America. Its name comes from the Greek word \u03b4\u03c1\u1fe6\u03c2 (drys) meaning 'tree, oak' and \u03c3\u03b1\u03c5\u03c1\u03bf\u03c2 (sauros) meaning 'lizard' or tall oak lizard.\"<\/p>\n\n\n\n

Dryosaurus fossils were found in the late 19th century in the western United States. It lived alongside Apatosaurus, Diplodocus, Brachiosaurus and many other dinosaurs. It was classified as an ornithischian dinosaur, meaning it had a bird-like hip structure. <\/p>\n\n\n\n

Dryosaurus was a bipedal dinosaur and a fast and agile runner with strong legs. It also had short arms, a long neck, tall legs, a horned beak and a stiff tail as a counterweight. Its eyes were quite large, leading many to believe that it possessed clear vision. It had oak-shaped teeth and mainly used its \"cheek teeth,\" which were dense molars, and the cheek pouches prevented food loss when chewing. It was a herbivorous dinosaur, meaning that it ate only plants such as conifers, cycads and ginkgos.<\/p>\n\n\n\n

Dryosaurus lived in a semi-arid environment with well-defined wet and dry seasons. It stayed in dense forest areas to feel comfortable. <\/p>\n\n\n\n

He was between 8 and 14 feet tall and weighed between 170 and 200 pounds. What a big baby he was!<\/p>\n\n\n\n
