       A very small sauropod,‭ ‬Rayososaurus is considered to be very similar to another genus called Rebbachisaurus.‭ ‬Because Rayososaurus is from South America and Rebbachisaurus is from Africa,‭ ‬this has given rise to the notion that these two continents were joined for much longer than previously thought back in the Cretaceous.
