Ornithopsis

Ornithopsis (meaning "bird-likeness") was a medium-sized Early Cretaceous sauropod dinosaur, from England. It has been considered a synonym of the wastebasket taxon Pelorosaurus, but recent research suggests that this is not as clear-cut as supposed. While Pelorosaurus is synonymous with several species of Ornithopsis, other genera are also considered synonyms, and the type species is since the nineties often seen as valid.
