       Gyposaurus is a genus of sauropodomorph dinosaur that technically does not exist anymore.‭ ‬Two species have been named,‭ ‬the type species G.‭ ‬capensis from South Africa,‭ ‬and G.‭ ‬sinensis from China.‭ ‬Doubts were cast upon the validity of the type species in‭ ‬1976‭ ‬when a study by Galton and Cluver came to the opinion that G.‭ ‬capensis was actually a specimen of Anchisaurus.‭ ‬In‭ ‬1981‭ ‬however,‭ ‬Michael Cooper synonymized G.‭ ‬capensis with Massopondylus,‭ ‬something that has gained popular acceptance among other palaeontologists.‭
       Now that the type species of Gyposaurus has been invalidated,‭ ‬G.‭ ‬sinensis cannot really be referred to as Gyposaurus since the fossils that the species were originally compared to are no longer part of the genus.‭ ‬In the past G.‭ ‬sinensis has also been considered to be a synonym to another genus,‭ ‬this time Lufengosaurus,‭ ‬a very common sauropodomorph known from China’s Lufeng Formation,‭ ‬the same fossil formation that the fossils of G.‭ ‬sinensis came from.‭ ‬However in‭ ‬2004,‭ ‬a study by Galton and Upchurch came to the conclusion that G.‭ ‬sinensis most probably represents its own genus.
       Great care should be taken not to confuse Gyposaurus with Gryposaurus,‭ ‬a genus of hadrosaurid dinosaur that lived during the late Cretaceous.
