Cultural significance

Diplodocus has been a famous and much-depicted dinosaur as it has been on display in more places than any other sauropod dinosaur. Much of this has probably been due to its wealth of skeletal remains and former status as the longest dinosaur.

The donation of many mounted skeletal casts of " Dippy " by industrialist Andrew Carnegie to potentates around the world at the beginning of the 20th century did much to familiarize it to people worldwide. Casts of Diplodocus skeletons are still displayed in many museums worldwide, including D. carnegii in a number of institutions.

The project, along with its association with 'big science', philanthropism, and capitalism, drew much public attention in Europe. The German satirical weekly Kladderadatsch devoted a poem to the dinosaur:

"Le diplodocus" became a generic term for sauropods in French, much as "brontosaur" is in English.

D. longus is displayed the Senckenberg Museum in Frankfurt (a skeleton made up of several specimens, donated in 1907 by the American Museum of Natural History), Germany. A mounted and more complete skeleton of D. longus is at the Smithsonian National Museum of Natural History in Washington, DC, while a mounted skeleton of D. hallorum (formerly Seismosaurus), which may be the same as D. longus, can be found at the New Mexico Museum of Natural History and Science.

A war machine (landship) from WW1 named Boirault machine was designed in 1915, later deemed impractical and hence given a nickname " Diplodocus militaris ".
