Dinosaur Zigongosaurus is a genus of sauropod dinosaur from the Middle Jurassic-Late Jurassic-age Shaximiao Formation of Zigong, Sichuan, China. Whichever genus it turns out to be, as a mamenchisaur- or omeisaur-like sauropod it would have been a large, quadrupedal herbivore with a long neck. It is regarded as a medium- to large-sized sauropod, with a length of around 15 meters (50 feet). All these Dinosaur Zigongosaurus pictures were collected from the internet. Enjoy!
