Incredible Discovery in a Polish Cave

The world’s oldest known boomerang has been discovered in a Polish cave, some 23,000 years after the device was fashioned from a mammoth tusk. The two-foot-long device is called a boomerang by the researchers because of its shape, rather than any proven ability to return to the person who throws it. It’s returning ability may be hampered by manufacturing flaws or later damage, and it is impossible to verify in an archaeological specimen. In ancient times, boomerangs were used on nearly all inhabited continents. The polishing flattened one face of the boomerang while rounding the other. The discovery has the potential to revolutionize our understanding of paleolithic game-hunting techniques.
