"Such a perfect object." The world's oldest boomerang is older than previously thought, casting new light on the ingenuity of humans living at the time. The tool, around the size of a baseball bat, was found inside a cave in Poland in 1985. It was originally dated to be around 30,000 years old, but new radiocarbon dating techniques used by researchers at the University of Bologna in Italy say it could be closer to 39,000 and 42,000 years old. Dr Sahra Talamo said it gives a "remarkable insight" into human behaviour and how Homo sapiens were living 40,000 years ago. Archaeologists say it was fashioned from a mammoth's tusk with an astonishing level of skill and kept in good shape by whoever used it. And yes - it would have flown when it was thrown, but it’s unlikely to have ever returned. Tap the link in BBCNews's bio to find out what researchers think it was used for.
