Dryosauridae was a family of primitive iguanodonts, first proposed by Milner & Norman in 1984. They are known from Middle Jurassic to Early Cretaceous rocks of Africa, Europe, and North America.
Classification
Until recently, many dryosaurids have been regarded as dubious (Callovosaurus and Kangnasaurus) or as species of the type member, Dryosaurus (Dysalotosaurus, Elrhazosaurus and Valdosaurus). However, more recent studies redescribe these genera as valid. Under the Phylocode, Madzia et al. (2021) formally defined Dryosauridae as "the largest clade containing Dryosaurus altus but not Iguanodon bernissartensis." The cladogram below follows their chosen reference phylogeny, taken from the description of Orthomerus dolloi.
