Eousdryosaurus is a genus of small ornithopod dinosaur that lived in Portugal during the late Jurassic. The name Eousdryosaurus means ‘eastern Dryosaurus’, a reference to how Eousdryosaurus is similar to the genus Dryosaurus, but globally lived further to the east, Eousdryosaurus in Portugal, and Dryosaurus in North America.
