Guide Note

Supersaurus was a genus of four-legged, herbivorous dinosaur that lived during the late Jurassic period. Although only a few bones have been discovered, the size of the gathered fossils indicates that it was an extremely large creature. It featured a small head on a long neck, and a long, tapering tail.
