Experts who unearthed a 200,000-year-old mammoth graveyard say it is “one of Britain’s biggest Ice Age discoveries in recent years”.
Archaeologists found the remains of five animals, including two adults, two juveniles, and an infant, at a quarry near Swindon.
The dig began after two keen fossil hunters spotted a Neanderthal hand axe.
Officials from archaelogical organisation DigVentures said that what they went on to find was “exceptional”.
The remains belong to a species of Steppe mammoth, an ancestor of the Woolly mammoth.
Close to the mammoth remains, the team also found a number of stone tools made by Neanderthals.
DigVentures began the excavations after being alerted to the site by Sally and Neville Hollingworth, from Swindon.
Ms Hollingworth said: “We were originally hoping to find marine fossils, and finding something so significant instead has been a real thrill.
