Archeologists in Norway discovered an arrow shaft that appears to be from the Stone Age, meaning it is approximately 4,000 years old.

The discovery was made on the side of Mount Lauvhøe, which stands at just over 6,500 feet in Norway's Lom Municipality. Archeologists had found arrows from the Iron and Middle ages when they last surveyed the area in 2017. However, this arrow shaft was found after ice at the site melted away in recent years, according to Lars Holger Pilø, co-director Secrets of the Ice, part of Norway's Department of Cultural Heritage.

He said the discovery predates earlier finds by more than 2,000 years, which adds a lot more "time depth" to the site. Researchers can determine the age of the artifact by its shape, but will submit a sample of the wood for carbon dating once the field season is over.
