A 5,000-year-old cow tooth found near Stonehenge provides evidence linking the monument's bluestones to Wales, suggesting cattle may have helped transport the stones, and highlights the complex movement and sourcing of materials in Neolithic Britain.
A recent study challenges the theory that the Newall Boulder at Stonehenge was transported by glaciers, instead supporting the idea that Neolithic humans actively quarried and moved the stones from Wales around 3000 BCE, based on petrographic analysis and lack of glacial evidence in the area.
A study led by researchers at Aberystwyth University has challenged a century-old theory about Stonehenge's Altar Stone, suggesting it may not have come from the same source as the other stones used in the monument's construction. Previous theories proposed that the Altar Stone originated from the Old Red Sandstone formation in west Wales, like the other bluestones. However, new analyses have revealed that the Altar Stone's composition and high barium content distinguish it from the basin and bluestone samples in the Anglo-Welsh Basin. This discovery raises doubts about the Altar Stone's origin and suggests the need to broaden the search geographically and stratigraphically.
