Amateur archaeologists excavating a Bronze Age site in the United Kingdom have discovered a cache of unusual stone tools unlike any that have been found before.
The tools appear to have been deposited deliberately — perhaps ceremonially — in what would have been a stream around 4,500 years ago, according to the researchers.
Around 20 of the roughly triangular stone hand tools, of various sizes, were found at the excavation site in the Clwydian Range, a series of hills in Denbighshire in northeast Wales, by the Clwydian Range Archaeological Group (CRAG) during four weeks of excavations in July and August.
