Diplodocus (/dɪˈplɒdəkəs/,[3][4] /daɪˈplɒdəkəs/,[4] or /ˌdɪploʊˈdoʊkəs/[3]) was a genus of diplodocid sauropod dinosaurs, whose fossils were first discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a Neo-Latin term derived from Greek διπλός (diplos) "double" and δοκός (dokos) "beam",[3][5] in reference to the double-beamed chevron bones located in the underside of the tail, which were then considered unique.
The genus of dinosaurs lived in what is now mid-western North America, at the end of the Jurassic period. It is one of the more common dinosaur fossils found in the middle to upper Morrison Formation, between about 154 and 152 million years ago, during the late Kimmeridgian Age.[6] Although it may have made it into the Tithonian.[7] The Morrison Formation records an environment and time dominated by gigantic sauropod dinosaurs, such as Apatosaurus, Barosaurus, Brachiosaurus, Brontosaurus, and Camarasaurus.[8] Its great size may have been a deterrent to the predators Allosaurus and Ceratosaurus: their remains have been found in the same strata, which suggests that they coexisted with Diplodocus.
Diplodocus is among the most easily identifiable dinosaurs, with its typical sauropod shape, long neck and tail, and four sturdy legs. For many years, it was the longest dinosaur known.
Although it narrowly failed to win the race with the New York Museum of Natural History in 1905, the Diplodocus carnegii is the most famous dinosaur skeleton today, due to the large number of casts in museums around the world
