Archaeologists in England have discovered more than two dozen monumental pits dotting the countryside in Bedfordshire, north of London.
Radiocarbon dating of materials retrieved from the prehistoric site revealed that the round, steep-sided holes were created around 7,700 to 8,500 years ago during the Mesolithic, also known as the Middle Stone Age, according to a statement from the Museum of London Archaeology, which made the finding alongside Albion Archaeology, a U.K.-based archaeological company.
