Amargasaurus

Restoration

Amargasaurus is a sauropod dinosaur of Cretaceous South America.

DescriptionEdit

Amargasaurus reached only 10 meters in length, but its most distinguishing feature was a row of long spines running down its neck and back. It has been speculated that these spines may have supported a sail, but paleontologist Gregory S. Paul argued that this would decrease neck flexibility and instead suggested that they were covered with a horny sheath.[1]

DiscoveryEdit

Amargasaurus fossils were first discovered in Argentina. It was named in 1991 by Jose Bonaparte and his colleagues.[2]

DietEdit

Like all sauropods, Amargasaurus was a herbivore.
