Fossil remains for this Dinosaur have been found in SW United States

Supersaurus was definitely one of the largest plant eaters of all time, and probably the largest member of the family that included Diplodocus . At just under 100 feet long, it was as long as three school buses! Its neck alone was 40 feet long.

Supersaurus is known from only a few bones, but these bones are enormous. The first bone found, a scapulacoracoid (shoulder bone) was over eight feet (2.4 m) long. James Jensen, one of North America's most prolific dinosaur hunters, discovered this creature in 1973 and excavated it in 1979. The bones are so large that some are still unprepared. Bones that were originally assigned to Ultrasauros  have now been identified as being from Supersaurus.
