Rebbachisaurus (meaning “Ait Rebbach lizard”) is an genus of sauropods belonging to the superfamily Diplodocoidea which lived in the Late Cretaceous period in Africa and possibly South America about 99-97 million years ago. The remains that are believed to be belonging to Rebbachisaurus have been discovered within Morocco, Niger, Algeria, Tunisia and possibly also Argentina (if Rayososaurus is the identical animal to Rebbachisaurus) however it is only Moroccan remains are able to be linked to the genus in no doubt. It is the discovery of Rayososaurus is the South American sauropod nearly identical to Rebbachisaurus that may be the identical animal as Rebbachisaurus is a strong evidence that there was an underlying land connection that connected Africa as well as South America during the Early Cretaceous even after the common belief that the two continents were separated.
Between the 8th of October, 1948 until 3 January 1952 Rene Lavocat collected the holotype of Rebbachisaurus garasbae (MNHN-MRS 1958) consisting of 10 ribs, the left shoulder blade eleven vertebrae, a sacrum, an humerus and two bones likely belonging to the pelvis, found in the Aoufous Formation at Gara Sbaa, Errachidia in Morocco. He named the species R. garasbae within the same year. However, just the right shoulder blade as well as one vertebra of the string of eleven vertebrae were initially described, only in a brief manner with no illustrations. The fossils remained undescribed and largely ignored until 2015 in which Jeffrey Wilson and Ronan Allain cleaned the holotype, and then described the remaining fossils Lavocat did not describe in 1954. Another specimen, made up of a single vertebra up to 1.45 meters (4.8 feet) tall when it is complete (also located in Aoufous) has been identified as belonging the name of R. Garasbae.
A different species was described after de Lapparent in 1960, Rebbachisaurus tamesnensis. The specimen of the type was collected from Lapparent from the Continental intercalaire Formation (initially believed to be found at Irhazer Shale) in Gall Locality Irhazer Shale) of Niger is believed to be composed of two humeri as well as two femora. There is also an additional specimen made up of four teeth that were not mangled A dentary fragment that has three teeth, more than 100 vertebrae, six chevrons five scapulae, 12 of the ribs and an ischia, an ilium and a variety of limb components, but the material from this taxon was gathered from numerous locations across the Sahara like many sites in the Elrhaz Formation of Niger, and it is not a reference to Rebbachisaurus.
The third species was identified in 1995 by Calvo as well as Salgado in 1995. Rebbachisaurus tessonei. It was found within the Candeleros Formation in Argentina, close to the spot the place where the holotype for Giganotosaurus carolinii was first discovered. The species was then moved into the new Limaysaurus genus in 2004. Limaysaurus in 2004.
It is widely thought to be it is the rebbachisaurid Rayososaurus agrioensis, which was named in 1996 by Jose Bonaparte in 1996, is a synonym for Rebbachisaurus garasbae. Rayososaurus is very like Rebbachisaurus however there’s a bit of disagreement about the fact that Rayososaurus is indeed a distinct species of the genus. However the morphological and temporal distinctions suggest that the distinction is valid because Rayososaurus is recognized in the Candeleros Formation of Argentina, and Rebbachisaurus is identified from the Aoufous Formation of Morocco.
