Supersaurus (meaning "super lizard") was a diplodocid dinosaur discovered in a rock formation in the U.S. state of Colorado in 1972, alongside bones of a Brachiosaurus. The holotype of Supersaurus is a large Scapular measuring about 2.4 meters long, making it taller than most adult humans. A few other bones from the quarry were referred to Supersaurus such as an ischium, pubis, a pelvis and various vertebra.

In 2007 WDC DMJ-021 more complete diplodocid specimen was referred to Supersaurus. Supersaurus may have been up to 34 meters (112 feet) long, making it the largest member of the diplodocid family known from relatively complete remains.

• The dermal spines shown here aren't known in Supersaurus but these are known from another diplodocid, probably Kaatedocus. Their arrangement on the body is speculative.
