Dryosauridae is an extinct family of herbivorous bipedal ornithopod dinosaurs, first proposed by Milner & Norman in 1984. They are known from Middle Jurassic to Early Cretaceous rocks of Africa, Europe, and North America.
Dryosauridae was first proposed in 1984 by British paleontologists Andrew R. Milner and David B. Norman, as a family to unite the early ornithopods Dryosaurus, Valdosaurus, and possibly Parksosaurus and Mochlodon. Milner and Norman separated these taxa from the family Hypsilophodontidae as they showed greater similarity with hadrosaurids and iguanodontids. The spelling had previously been used as a typographical error by Deraniyagala in 1939 for Dyrosauridae. Dryosaurids were cursorial animals adapted for running.
