Experts say they have confirmed for the first time the precise origin of some of the rocks at Stonehenge.
It has long been suspected that rhyolites from the northern Preseli Hills helped build the monument.
But research by National Museum Wales and Leicester University has identified their source to within 70m (230ft) of Craig Rhos-y-felin, near Pont Saeson.
The museum's Dr Richard Bevins said the find would help experts work out how the stones were moved to Wiltshire.
For nine months Dr Bevins, keeper of geology at National Museum Wales, and Dr Rob Ixer of Leicester University collected and identified samples from rock outcrops in Pembrokeshire to try to find the origins of rhyolite debitage rocks that can be found at Stonehenge.
By detailing the mineral content and the textural relationships within the rock, a process known as petrography, they found that 99% of the samples could be matched to rocks found in this particular set of outcrops.

Aliens.
it has to be the Brits. Only they have the wit required to do something like Stonehenge.
Hmmm...does this fit into the scheme mentioned in the knights of the round table. The books are close by. I think I flagged it at one time.
Philistine that I am, as I read this the refrain “Now they know how many holes it takes to fill the Albert Hall...” kept running through my head.
