Potentially important portal dolmen found in Pembrokeshire

At www.independent.co.uk/history/secrets-of-the-earliest-britons-could-be-h… … archaeologists have discovered the remains of an Early Neolithic portal dolmen in a field in Pembrokeshire – together with a linear alignment of stones (a straight line in other words). In addition, and what is expected to be most revealing, the grave has human bone and sherds of decorated pottery. However, the pottery dates to the Late Neolithic, it is being suggested (after 3000BC) but the portal dolmen probably goes back nearly to 4000BC.
