individuals.
One of the most notable details of Rebbachisaurus are the tall neural spines of the vertebrae, which either stood proud from the back, or supported a sail or hump that ran along the spine. Aside from this Rebbachisaurus was a fairly generic diplodocid sauropod with a large build, long neck and whip-like tail. However, the discovery of another very similar genus of sauropod called Rayososaurus in Argentina has raised the notion that South America and Africa may have been joined by a land bridge for longer than previously thought. The idea of the two being joined has always been around, since the two continents seem to have almost matching types of dinosaurs (for example, spinosaurids and carcharodontosaurids) during the Early Cretaceous. If the two continents were joined for longer, then that raises the possibility for what may one day be found in a place like South America which was for a long time assumed to have been completely isolated from the other continents early on in the Cretaceous.
