''Rebbachisaurus'' is a genus of sauropod dinosaur of the superfamily Diplodocoidea, up to long,〔Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'' (Winter 2010 Appendix. )〕 that lived during the Early–Late Cretaceous period in Africa about 99 million years ago. This massive four-legged plant-eating animal had a small head, a long, graceful neck and a whiplike tail. ''Rebbachisaurus'' is distinguished from other sauropods by its unusually tall, ridged back. The discovery of ''Rayososaurus'', a South American sauropod nearly identical to ''Rebbachisaurus'', supports the theory that there was still a land connection between Africa and South America during the Early Cretaceous, long after it was commonly thought the two continents had separated. ==References==
