Large Rebbachisaurus garasbae

Rebbachisaurus is a genus of sauropod dinosaur of the superfamily Diplodocoidea that lived during the Early-Late Cretaceous period in Africa about 99 million years ago. It reached lengths of up to 20 meters (65 feet) long. This massive four-legged plant-eating animal had a small head, a long, graceful neck, and a whip-like 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 that the two continents had separated.
