Dippy - a complete cast of a diplodocus skeleton - is Britain's most famous dinosaur. It has resided at the Natural History Museum in London since 1905 and is now on show in Coventry where it is "dinosaur-in-residence" at the Herbert Art Gallery & Museum .

Dippy, the star attraction in the huge entrance hall of the Natural History Museum from 1979 to 2018, is now on tour around the UK, with Coventry as its latest stop. It had previously been shown in Dorchester, Birmingham, Belfast, Glasgow, Newcastle, Cardiff, Rochdale, Norwich and London.
So what is it that makes Dippy so popular? I got a sense of the dino's appeal in August 2021 when I gave a lecture under the Dippy skeleton in Norwich Cathedral.

The lecture was about dinosaur feathers and colours. It highlighted new research that identified traces of pigment in the fossilised feathers of birds and dinosaurs. I wanted to highlight the enormous advances in the ways we can study dinosaurs that had taken place in just a century.
Before arriving, I thought that Dippy would fill the cathedral - after all the skeleton is 26 metres long and it had filled the length of the gallery at the Natural History Museum. However, Dippy was dwarfed by the gothic cathedral's scale. In fact, the building is so large that five Dippys could line up, nose to tail, from the great west door to the high altar at the east end.
This sense of awe is one of the key reasons to study palaeontology - to understand how such extraordinary animals ever existed.
I asked the Norwich cathedral canon why they had agreed to host the dinosaur, and he gave three answers. First, the dinosaur would attract lots of visitors. Second, Dippy is from the Jurassic period, as are the rocks used to construct the cathedral. Finally, for visitors it shared with the cathedral a sense of awe because of its huge size. Far from being diminished by its temporary home, visitors still walked around and under Dippy sensing its grandeur.
Dippy arrived in London in 1905 as part of a campaign for public education by the Scottish-American millionaire Andrew Carnegie (1835-1919). At the time, there was a debate in academic circles about the function of museums and how far professionals should go in seeking to educate the public.
There was considerable reticence about going too far. Many professors felt that showing dinosaurs to the public would be unprofessional in instances where they moved from description of facts into the realm of speculation. They also did not want to risk ridicule by conveying unsupported information about the appearance and lifestyle of the great beasts. Finally, many professors simply did not see such populism as any part of their jobs.
But, at that time, the American Museum of Natural History was well established in New York and its new president, Henry Fairfield Osborn (1857-1935) was distinctly a populist. He sponsored the palaeo artist Charles Knight (1874-1953), whose vivid colour paintings of dinosaurs were the glory of the museum and influential worldwide. Osborn was as hated by palaeontology professors as he was feted by the public.
Carnegie pumped his steel dollars into many philanthropic works in his native Scotland and all over America, including the Museum of Natural History in Pittsburgh. When he heard that a new and complete skeleton of a diplodocus had been dug up in Wyoming, he bought it and brought it to his new museum. It was named as a new species, Diplodocus carnegiei.
On a visit to Carnegie's Scottish residence, Skibo Castle, King Edward VII saw a sketch of the bones and Carnegie agreed to donate a complete cast of the skeleton to Britain's Natural History Museum.
The skeleton was copied by first making rubber moulds of each bone in several parts, then filling the moulds with plaster to make casts and colouring the bones to make them look real. The 292 pieces were shipped to London in 36 crates and opened to the public in May 1905. Carnegie's original Dippy skeleton only went on show in Pittsburgh in 1907, after the new museum building had been constructed.
Carnegie had got the royal bug and donated further complete Dippy casts to the great natural history museums in Berlin, Paris, Vienna, Bologna, St Petersburg, Madrid, Munich, Mexico City and La Plata in Argentina. Each of these nations, except France, had a king or tsar at the time. The skeletons went on show in all these locations, except Munich, and Dippy has been seen by many millions of people in the past 120 years.
Dippy's appeal
Dippy's appeal is manifold. It's huge - we like our dinosaurs big. It has been seen up close by more people around the world than any other dinosaur. It also opens the world of science to many people. Evolution, deep time, climate change, origins, extinction and biodiversity are all big themes that link biology, geology, physics, chemistry and mathematics.
Also, since 1905, palaeontology has moved from being a largely speculative subject to the realms of testable science. Calculations of jaw functions and limb movements of dinosaurs can be tested and challenged. Hypotheses about physiology, reproduction, growth and colour can be based on evidence from microscopic study of bones and exceptionally preserved tissues, and these analyses can be repeated and refuted.
Dippy has witnessed over a century of rapid change and its appeal is sure to continue for the next.
Dippy is on display at the Herbert Art Gallery & Museum in Coventry until February 21 2026.
