Amateur fossil hunters inspired by films such as Ammonite are descending on beaches in droves.
Thousands of enthusiasts dreaming of walking with dinosaurs have taken up the craze as lockdown eases.
It is so popular, guided fossil walks are selling out and online demand for geological equipment has boomed.
Experts believe would-be palaeontologists have been galvanized by movies such as Ammonite, about Victorian fossil-collector Mary Anning, and The Dig, starring Ralph Fiennes, about the excavation of a Saxon ship in Suffolk.
Last month fossil collectors scoured the beach at Seatown, Dorset, after a 430ft sandstone cliff collapsed in the biggest UK rockfall for 60 years.

Hunters sifted through the 4,000 tonnes of rubble despite warnings to stay away for safety reasons.
Some eight miles west, in the cliffs of Lyme Regis, was where Anning – played by Kate Winslet – discovered dinosaur skeletons. In the film, released last year, she has a relationship with a visitor’s wife, played by Saoirse Ronan.
The Lyme Regis Museum, which is on the site of Anning’s former home, expects 5,000 to 6,000 people on their fossil walks this year.
Museum director David Tucker said: “We’re going to be packed out through the summer. When the tides allow, we’ll take 40 people out a day.
“The school holidays will be booked solid. I’ll have to turn people away.”
Searches on eBay UK for geological hammers and field lenses are up, year on year, by 84% and 500% respectively.
Palaeontologist Dr Fiann Smithwick said: “This summer will see the highest numbers of people descending on the coasts to look for fossils ever.”
She added: “Going for a walk with a specific purpose and the chance of finding pieces of never-before-seen ancient history is a way to connect to a distant past that for most people is unimaginable.”
