Dryosaurus is a genus of an ornithopod dinosaur that lived in the Late Jurassic period. It was an iguanodont (formerly classified as a hypsilophodont). Fossils have been found in the western United States and were first discovered in the late 19th century.
Based on known specimens, they had been estimated to have reached up to 3 metres (9.8 ft) long and to have weighed up to 100 kilograms (220 lb). However, as no known adult specimens of the genus have been found, the adult size remains unknown.
Dryosaurus subsisted primarily on low growing vegetation in ancient floodplains. A quick and agile runner with strong legs, Dryosaurus used its stiff tail as a counterbalance. It probably relied on its speed as a main defense against carnivorous dinosaurs.
