A rare late Bronze Age arrowhead made from meteoric iron found in Mörigen near Lake Biel, Switzerland, is believed to have orginated from Estonia. Scientists who have extensively studied the artefact conclude that the arrowhead is most likely from the Kaali järv meteorite that crashed onto the Estonian island of Saaremaa around 1,500 BCE. The discovery of the artefact has shocked experts as it was found thousands of kilometres from where its raw material came.
The impact of the Kaali järv meterorite left behind nine craters. The largest is 110 metres in diametre. Meteoritic iron is very rare and was used to forge pre-Iron Age items such as tools and weapons. Scientists believe that the arrowhead discovered in a collection two years ago was made from fragments of the Kaali meterorite, based on three independent studies that match time, size and geographic location. Organic matter from the base of the Kaali järv lake also strongly backs the claim.
