Supersaurus was a sauropod dinosaur, a relative of Diplodocus. It was found in the Upper Jurassic Morrison Formation of Colorado in 1972.[1]
In most respects, Supersaurus is similar in to Apatosaurus, but it is less robustly built. It has elongated cervical vertebrae, resulting in one of the longest known sauropod necks.[2] It was up to 33 to 34 meters (108 to 112 ft) in length, and a weight of 35 to 40 tons.[3]
A new and much more complete specimen of Supersaurus, nicknamed 'Jimbo', WDC DMJ-021, was found in Converse County, Wyoming in 1996. It is currently being prepared and was described in 2007. Its bones are held at the Wyoming Dinosaur Center.
