Dippy (London) Dippy (London) Dippy is a plaster cast replica of the fossilised bones of the type specimen of "Diplodocus carnegii". The long cast was displayed from 1979 to 2017 in the Hintze Hall, the central entrance hall of the Natural History Museum, in London. The genus "Diplodocus" was first described in 1878 by Othniel Charles Marsh. The fossilised skeleton from which Dippy was cast was discovered in Wyoming in 1898, and acquired by the Scottish-American industrialist Andrew Carnegie for his newly-founded Carnegie Museum of Natural History in Pittsburgh. The bones were soon recognised as a new species, and named "Diplodocus carnegii".
