The arrowhead was found in the 19th century during excavations at a Paleolithic site dating from 900-800 BC, according to a statement issued by the Museum of Natural History in Bern, which conducted the research.
Such metal objects from meteorites dating from before the beginning of the Iron Age (800 B.C.) are very rare. There are only 55 of them in Eurasia and the African continent. The scientists set out to find out whether the arrowhead came from the dispersal area of the Douanne Mountain meteorite, just a few kilometers away.
To the researchers' surprise, the arrowhead was not made from one of the 2,000 fragments of the iron meteorite that fell on the Douanne Moutain 170,000 years ago. It contained almost twice as much nickel compared to those fragments.
The most likely origin, given the composition of the metal, is the Kaalijärv meteorite that fell around 1500 BC in Estonia and produced several craters up to 100 metres in diameter. This suggests that a trade in these fragments had developed.
The analyses done on the arrowhead showed beyond doubt the metal's meteorite origin, according to this work published in the Journal of Archaeological Science. The research was conducted by scientists from University of Bern with the help of colleagues in Germany and the Paul Scherrer Institute in Switzerland.
The finding raises the possibility that other objects in European museum collections are also of Estonian origin, conclude the scientists. They suggest that analyses be carried out in this direction.
