Archaeologists from the University of Exeter claim that the bones were sourced from animal graveyards.

The majority of the bones came from mammoths but they also found the remains of reindeer, foxes and horses.

The researches also found remains of charred wood and other plant remains, indicating that communities who lived there had learned where to forage for edible plants during the Ice Age.

Dr Alexander Pryor, who led the study, said: ''These finds shed new light on the purpose of these mysterious sites.

''Archaeology is showing us more about how our ancestors survived in this desperately cold and hostile environment at the climax of the last Ice Age.''
