Experts have found more tracks at the UK's biggest ever dinosaur footprint site.

In 2024 around 200 dinosaur prints, from 166 million years ago, were found in Oxfordshire by a worker driving a digger.

More than 100 scientists, students and volunteers have been part of the excavation dig at Dewars Farm Quarry to uncover one of the longest trackways found anywhere in the world.

The site has long been linked with dinosaurs. Some trackways were discovered here in the 1990s, however this year, the team unearthed even more tracks in a different part of the quarry.

Hidden under tonnes of rock, experts have discovered a giant dinosaur superhighway.

"These footprints are insanely big," explains Emma Nicholls from Oxford University's Museum of Natural History.

"They're the massive footprints of a sauropod dinosaur; probably Cetiosaurus, which is a dinosaur that we know was found in this area."

Reaching from one end of the quarry to the other, the trail extends 220m, one of the longest trackways found anywhere in the world, ever.

"We're uncovering something that people have never seen before," says University of Birmingham palaeontologist Kirsty Edgar.

"It's so rare to find something this big."

During the dig in 2024, scientists discovered five sets of dinosaur tracks made by two different species of dinosaur - sauropods and Megalosaurus.

Four of the tracks the scientists discovered were made by sauropods, giant plant-eating dinosaurs which walked on four legs.

Their footprints look a bit like an elephant's - only much much bigger - these dinos reached up to 18m in length.

It's thought other tracks were made by a Megalosaurus.

These carnivorous creatures, walked on two legs and are some of the biggest predatory dinosaurs known of from the Jurassic period in Britain.
