Named By: R. Broom - 1911.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Sauropodomorpha.
Species: ‘G. capensis' (type), G. sinensis.

Time period: Hettangian of the Jurassic.
Fossil representation: Partial post cranial skeletal remains.
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.
actually a specimen of Anchisaurus.
In 1981 however, Michael
Cooper synonymized G. capensis with Massopondylus,
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.
