A mammoth tusk artefact discovered in a Polish cave could be Europe’s earliest example of a boomerang and even the oldest tool of its kind in the world, archaeologists said.

The tusk was found along with what seemed like a human little finger or toe bone fossil at the Obłazowa cave in Poland, and it could be nearly 40,000 years old, according to a study published in the journal PLoS One.
