Reporting for BBC News Wales, Neil Prior writes –
 
New research has cast fresh doubt on the journey which the Stonehenge Bluestones took from Pembrokeshire to the site of the pagan monument. Since the 1920s, geologists have strongly suspected that the ‘spotted dolerite’ Bluestones, which form Stonehenge’s inner ring, originated from Mynydd Preseli in the north of the county. However, whilst the new findings have also linked a second type of stone – rhyolites – to the area, they call into question how the stones arrived in Wiltshire.”
