Dippy is a compositeDiplodocus skeleton. The original skeleton is inPittsburgh'sCarnegie Museum of Natural History, and theholotype of thespeciesDiplodocus carnegii. It is considered the most famous single dinosaur skeleton in the world, due to the numerousplaster casts donated byAndrew Carnegie to several major museums around the world at the beginning of the 20th century.[2][3] One well known cast in theUnited Kingdom was displayed at theNatural History Museum in London from 1905 until 2017.
The casting and distribution of the skeleton made the worddinosaur a household word;[4] for millions of people it became the first dinosaur they had ever seen.[5] It was also responsible for the subsequent popularity of the entire genusDiplodocus, since the skeleton has been on display in more places than any othersauropod dinosaur.[6]
Its discovery was catalyzed by the announcement of the excavation of a large thigh bone (unrelated to Dippy) byWilliam Reed nearMedicine Bow, Wyoming in December 1898.[7] On a return trip financed by Carnegie, Reed excavated Sheep Creek Quarry D in which he found the first part of Dippy's skeleton, a toe bone, on July 4, 1899.[8] Its discovery onIndependence Day, and its use in American diplomacy via Carnegie's international donations of replicas, led to its being nicknamed the "star-spangled dinosaur".[9] Dippy became the centrepiece of the Carnegie Museum of Natural History, such that the museum became known as "the house that Dippy built".[4][10]
In 2016, a petition to theInternational Commission on Zoological Nomenclature was being considered which proposed to makeDiplodocus carnegii the newtype species ofDiplodocus.[11] The proposal was rejected in 2018, andD. longus has been maintained as the type species.[11][12]
The genusDiplodocus was first described in 1878 byOthniel Charles Marsh.[citation needed] The skeleton was found in 1898 in the upper 10 metres (33 ft) of the Talking Rock facies of the Brushy Basin Member of theMorrison Formation, inAlbany County, Wyoming.[14]
In 1900,John Bell Hatcher was hired byWilliam Jacob Holland as curator of paleontology and osteology for theCarnegie Museum of Natural History, succeedingJacob Lawson Wortman.[7] Hatcher supervised the field expeditions, excavations, investigation and display of Dippy, and named the species for Carnegie.[7] Hatcher's monograph on the find was published in 1901 asDiplodocus Marsh: Its Osteology, Taxonomy, and Probable Habits, with a Restoration of the Skeleton.[7][15]
It is a composite skeleton comprising:[16]
The original skeleton has been on display at theCarnegie Museum of Natural History since April 1907, two years after the first cast was shown. The delay was due to construction work at the Pittsburgh museum, which needed expansion in order to house Dippy.[18] Today, the skeleton is part of theDinosaurs in Their Time exhibition.[19]
IndustrialistAndrew Carnegie financed the acquisition of the skeleton in 1898, as well as the donation of the casts at the beginning of the 20th century.[20][21] Carnegie paid to have casts made for display in many European capitals – including Berlin, Paris, Vienna, Bologna, St Petersburg and Madrid; one sent to Munich was never erected – as well as Mexico City and La Plata in Argentina, making Dippy the most-viewed dinosaur skeleton in the world.
His great-grandson, William Thomson, was quoted in 2019 explaining the donations: "By gifting copies to the heads of state of seven other countries as well as the UK, Carnegie hoped to demonstrate through mutual interest in scientific discoveries that nations have more in common than what separates them. He used his gifts in an attempt to open inter state dialogue on preserving world peace – a form of Dinosaur diplomacy."[22]
As director of the Carnegie Museums, William Holland supervised the donations of the casts. His trip to Argentina in 1912 was recorded by Holland in his 1913 travel bookTo the River Plate and Back. Holland noted a poem which had become popular among college students:[23][24]
Crowned heads of Europe
All make a royal fuss
Over Uncle Andy
And his old diplodocus.

TheLondon cast of Dippy came about when KingEdward VII, then a keen trustee of theBritish Museum, saw a sketch of the bones at Carnegie's Scottish home,Skibo Castle, in 1902, and Carnegie agreed to donate a cast to the Natural History Museum as a gift. Carnegie paid £2,000 for the casting inplaster of paris, copying the original fossil bones held by the Carnegie Museum (not mounted until 1907, as a new museum building was still being constructed to house it).[28]
The 292 cast pieces of the skeleton were sent to London in 36 crates, and the 25.6 metres (84 ft) long exhibit was unveiled on May 12, 1905, to great public and media interest, with speeches from the museum director ProfessorRay Lankester, Andrew Carnegie,Lord Avebury on behalf of the trustees, the director of the Carnegie MuseumWilliam Jacob Holland, and finally the geologist SirArchibald Geikie.[29] The cast was mounted in the museum'sReptile Gallery to the left of the main hall (until recently the gallery of Human Biology) as it was too large to display in the Fossil Marine Reptile Gallery (to the right of the main hall).[23][30]
Dippy was taken to pieces and stored in the museum's basement during the Second World War to protect it frombomb damage, and reinstalled in the Reptile Gallery after the war. The original presentation of the cast was altered several times to reflect changes in scientific opinion on the animal's stance. The head and neck were originally posed in a downwards position, and were later moved to a more horizontal position in the 1960s.[31] The cast in London became an iconic representation of the museum, and has featured in cartoons and other media, including the 1975 Disney comedyOne of Our Dinosaurs Is Missing.
Dippy was removed from the Reptile Gallery in 1979 and repositioned as the centrepiece of the main central hall of the museum, later renamed the Hintze Hall in recognition of a large donation byMichael Hintze.[31] Dippy replaced a mountedAfrican elephant, nicknamed George, which had been on display as the central exhibit in the main hall since 1907, with various other animal specimens. The elephant had itself replaced the skeleton of asperm whale which was the first significant exhibit in the hall and had been on display since at least 1895: earlier, the hall had been left largely empty. Dippy was originally displayed alongside a cast of aTriceratops skeleton, which was removed around 1993. The tail of theDiplodocus cast was also lifted to waft over the heads of visitors; originally it drooped to trail along the floor.[32]
After 112 years on display at the museum, the dinosaur replica was removed in early 2017 to be replaced by the 25 m (82 ft) long skeleton of a youngblue whale, dubbed "Hope". The whale had beenstranded on sandbanks at the mouth ofWexford Harbour, Ireland in March 1891. Its skeleton was acquired by the museum and had been displayed in the Large Mammals Hall (originally the New Whale Hall) since 1934.
The work involved in removing Dippy and replacing it with the whale skeleton was documented in aBBC Television special,Horizon: Dippy and the Whale, narrated byDavid Attenborough, which was first broadcast onBBC Two on July 13, 2017, the day before the whale skeleton was unveiled for public display.[33]
Dippy started a tour of British museums in February 2018, mounted on a new, more mobile armature.[34][35] Dippy has been on display at locations around the United Kingdom:[36][37]
Dippy returned to the Natural History Museum as part of a temporary exhibition in June 2022.[45] In February 2023, it was moved to moved to Coventry as a long-term loan to theHerbert Art Gallery and Museum in 2023.[46] A newbronze cast of Dippy, named Fern, has stood in the garden of the Natural History Museum since 2024.[27]
