In Depth

       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.
