Bizarre pits have been found in the UK thought to date back as far as 8,500 years when rising seas saw the country separated from the rest of Europe, leaving scientists baffled.
There are 25 of the pits in Linmere, Bedfordshire, with radiocarbon dating showing they are from the Middle Stone Age, a period which there is very little known.
It has left archaeologists “excited” to learn more from the pits which have been labelled a “nationally important prehistoric site”.
