'No evidence' Stonehenge bluestones quarried

There is "no evidence" some of the stones at Stonehenge that came from two Pembrokeshire quarries were excavated by man, a geologist has said.

Dr Dyfed Elis Gruffydd has disputed research, led by University College London (UCL), which found the bluestones came from outcrops at Carn Goedog and Craig Rhos-y-felin.

Following excavations, the team of archaeologists and geologists said the stones may have been first used in a local monument near the quarries and then dismantled and taken to Wiltshire.

But Dr Gruffydd said no evidence of human quarrying had been found at the sites.
