Description

Dryosaurus is a genus of late Jurassic ornithopod dinosaur. The name 'Dryosaurus' is derived from the Greek word 'drys' meaning 'tree' or 'oak', referring to the habitat these dinosaurs likely inhabited. This small and agile herbivore was likely dependent on its ability to evade carnivores in order to survive, being unable to defend itself by other means.

Discovery

Dryosaurus was originally classified as a hypsilophodon, due to similarities in size and shape. Subsequent studies have rejected this classification, based on anatomical differences: the number of toes differs, as does the hip and dental structure.The Tanzanian Dysalotosaurus is another dinosaur so similar in appearance to Dryosaurus that some paleontologists have claimed the two are synonymous. This synonymy has been cited as evidence for a land route between Africa and North America during the late Jurassic. Geographical maps do not indicate the existence of a such a land route, however, and a 1981 study by Peter Malcolm Galton identified several differences between the two animals.Without the existence of a land route during the late Jurassic, these similarities could be simply a case of the two genera having relatively recently diverged.

Paleoecology

Dryosaurus would have lived alongside predators such as Ceratosaurus and a large amount of Allosaurus. True to its name, Dryosaurus likely inhabited river-lining forests and savannahs. The flora of the time included fungi, mosses, and conifers.
