The 85ft-long (26m) plaster cast of a male Diplodocus skeleton attracted an extra 140,000 visitors to Birmingham Museum and Art Gallery (BMAG), with those visitors spending £4.2m during their visit according to research.
For the first time in more than a century, members of the public can see Dippy the Diplodocus outside of London.
It had been housed at the Natural History Museum in London since 1905, but is now on a three-year tour of the UK, starting with Dorset County Museum in Dorchester, near to the UK’s Jurassic Coast.
His position in the entrance hall has been filled by the skeleton of a blue whale skeleton, named Hope, which became stranded in 1891 in Wexford Harbour in Ireland.
According to BMAG, Dippy attracted more than double the number of visitors than it had during the same period last year.
The gallery said that the 244,548 visitors made Dippy the most successful temporary exhibition the gallery has ever had.
When Dippy was in Dorset County Museum, its presence tripled the visitor numbers for the venue in an entire year within just three months.
Alex Burch, the Natural History Museum’s head of exhibitions, said: “The success of the tour and the public response to Dippy has been staggering and means we are on course for meeting our aim of introducing Dippy to 1.5 million people.
“One of our biggest priorities at the Natural History Museum is making sure the riches of our national collection benefit communities right across the UK.
“Dippy’s tour is doing just that, and it has been made possible through the vision, ambition and collaboration of many partners – it is a great example of what can be achieved when regional and national institutions work together.”
Next, Dippy will be on display at the Ulster Museum in Belfast, where he will be from 28 September until 6 January.
