This Late Jurassic Sauropod thrived in a time when the Earth's warm temperatures encouraged rapid plant growth. Diplodocus needed a lot of food to keep it alive. Using rake-like teeth, this animal could have stripped an area of any vegetation very quickly, especially considering that there is evidence they traveled in herds.
Diplodocus' tail was about 45 feet (14m) long, which is one of the longest tails of any animal to have ever walked the Earth.
Like most Sauropods, Diplodocus' nostrils were actually high up on its forehead instead of at the end of its snout.
A recently discovered fossil of a skin impression suggests that this animal had spines along its neck.
