Due to a wealth of fossil remains, the first of which was found in the late 1870s, Diplodocus is one of the best-studied dinosaurs. The herbivorous dinosaur roamed western North America about 145 million years ago, during the late Jurassic period, walked on four legs, and had an extremely small brain and skull. One of the longest known sauropods, Diplodocus could grow to be 88 ft (27 m) long, most of which was neck and tail. With what man-made structure is it often compared? Discuss
