Bulldozers ripping their way through rural Somerset for the M5 revealed evidence which some people think has shattered accepted theories about Stonehenge.

For nearly 50 years archaeologists have believed that armies of men dragged the 'Blue-stones' to Stonehenge from the Prescelly Mountains of Pembrokeshire 150 miles away. They held that all this happened 4,000 years ago; but now a London geologist says their dates are possibly half a million years out.

Magnus Magnusson puts this theory to some of Britain's leading archaeologists. One of them, Dr Glyn Daniel, has his own view about the authenticity of a megalithic site in America which has claims to be as old as Stonehenge.

A dig at Swanscombe in Kent has lifted a rhinoceros skull from mud near the Thames; and at Carcassonne in southern France workers have found a Frenchman 200,000 years old.
