:''Not to be confused with Dyrosauridae'' Dryosaurids were primitive iguanodonts. They are known from Middle Jurassic to Early Cretaceous rocks of Africa, Europe, and North America. ==Phylogeny== 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.〔〔〔 The cladogram below follows Paul M. Barrett, Richard J. Butler, Richard J. Twitchett and Stephen Hutt (2011). }} }} }} }} }} According to an abstract at the SVP 2014 conference, ''Anabisetia'', ''Macrogryphosaurus'', and ''Trinisaura'', all from the Late Cretaceous of Gondwana, are members of Dryosauridae. If so, then Elasmaria would be a derived clade of Cretaceous dryosaurids.〔Poole, K., 2014. A new phylogeny of iguanodontian dinosaurs.
