Zigongosaurus like many other sauropods from China had very long neck. This is possible part of the dinosaur’s evolution so that it was able to reach up to vegetation that grew high up in the forest canopy. Zigongosaurus lived during the Late Jurassic period, about 150 million years ago. Chinese paleontologists discovered a very complete specimen of Zigongosaurus back in the 1970s. After studding their findings they came to a conclusion that it was a new species of dinosaur, but not everyone agrees with them. The dinosaur was named in 1976 after the region in China where it was discovered. Its name means “Zigong lizard.” Zigongosaurus grew to a length of 33 feet, most of which was made up by its long neck and tail. It is estimated that the dinosaur weighed as much as 20 tons. Like many other heavy sauropods which are slow moving, Zigongosaurus may have lived in herds. A single Zigongosaurus may have been defenseless against a predator, but they found strength by living in herds. There is speculation that Zigongosaurus was been wrongfully classed as a separate species of dinosaur. It is believed that Zigongosaurus is actually a Mamenchisaurus, which lived at the same time and in the same region in China. More fossils will have to be discovered before the puzzle is finally solved.
