Ornithopsis was a genus of sauropod dinosaur that lived in England during the early Cretaceous. Named in 1870 by Harry Govier Seeley, and like many European dinosaurs, Ornithopsis ended up being something of a waste basket taxon, and as time has gone on, fossils attributed to Ornithopsis have ended up being re-assigned to other genera. In terms of taxonomic assignment, Ornithopsis has crossed paths with genera such as Cetiosaurus, Cetiosauriscus, Bothriospondylus, and Brachiosaurus, but the long and the short of it is that only the type species of Ornithopsis, O. hulkei is considered to possibly be valid, though since this genus is only known by two partially preserved vertebrae, it would be difficult to assign further remains to Ornithopsis. A second species named O. leedsi which is still sometimes credited along with the type species, may actually represent a different genus.
