DiplodocusDiplodocus is a genus of sauropod dinosaur that was first discovered in 1878. The name derives from double chevron-shaped bones underneath the tail.
Diplodocus is one of the more common Jurassic dinosaurs found in what is now western North America, and particularly in the Morrison Formation of the western United States and Canada, which dates to some 150 to 147 million years ago. During this period, the area was dominated by huge sauropod dinosaurs such as Camarasaurus, Barosaurus, Apatosaurus and Brachiosaurus. Diplodocus was for many years the longest known dinosaur, and its size alone may have deterred predation from such fierce predators as Allosaurus and Ceratosaurus, whose remains are found in the same region.
