A 40,000-year-old mammoth tusk boomerang just turned up in a Polish cave, and it’s officially Europe’s oldest—and maybe the world’s! This thing looks just like the boomerangs used by Aboriginal Australians today (but it doesn’t come back). Archaeologists say it’s proof that ancient humans in Europe were way more inventive than we thought. Imagine carving a hunting tool from a mammoth tusk 40,000 years ago! #Archaeology #AncientHistory #Boomerang #History
