British researchers have unearthed some 200 dinosaur footprints dating back 166 million years in a find believed to be biggest in the UK.
The discovery was made by teams from Oxford and Birmingham Universities at a quarry in Oxfordshire in central England after a worker came across “unusual bumps” as he was stripping clay back with a mechanical digger, according to a new BBC documentary.
The site features five extensive trackways, with the longest continuous track stretching more than 150 metres (490 feet) in length.
Four of the five trackways uncovered are believed to have been made by a long-necked herbivorous dinosaur, most likely a cetiosaurus. The fifth set of tracks likely belongs to a nine-metre long carnivorous megalosaurus known for its distinctive three-toed feet with claws, according to the University of Birmingham.
“It’s rare to find them so numerous in one place and it’s rare to find such extensive trackways as well,” Emma Nicholls of Oxford University’s Museum of Natural History told AFP. The area could turn out to be one of the world’s biggest dinosaur track sites, she added.
A 100-strong team led by academics from Oxford and Birmingham excavated the tracks during a week-long dig in June.
The new footprints follow a smaller discovery in the area in 1997, when 40 sets were uncovered during limestone quarrying, with some trackways reaching up to 180 metres in length.
The researchers took 20,000 photographs of the latest footprints and created detailed 3D models of the site using aerial drone photography. It is hoped the discovery will provide clues about how dinosaurs interacted, as well as their size and the speeds at which they moved.
