Dryosauridae


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 or as species of the type member, Dryosaurus. 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.
