In Depth

       Unaysaurus is the first confirmed sauropodomorph dinosaur to be named from Brazil,‭ ‬though there is speculation that another genus named in‭ ‬1999‭ ‬called Teyuwasu might also be a sauropodomorph.‭ ‬The closest relative to Unaysaurus is thought to be the famous Plateosaurus from Germany.
