The World's Oldest Boomerang Is Even Older Than Scientists Thought, a New Analysis Suggests

  • Researchers at ObBazowa Cave in Poland announced the discovery of the oldest known mammoth-ivory boomerang, dated to 42,290–39,280 years ago, challenging assumptions about its origins.
  • Faced with earlier radiocarbon dates of around 18,000 years, Talamo's Bayesian modeling recalibrated the boomerang's age to approximately 39,280–42,290 years, resolving dating conflicts.
  • Bayesian modeling dates the site's main occupation between 42,810–38,550 cal BP, with the boomerang dating to 42,290–39,280 cal BP and found alongside a human phalanx.
  • The study suggests the European boomerang predates Australian wooden ones by 30,000 years, challenging the idea of boomerang origins being exclusive to Australians.
  • The discovery of a mammoth ivory boomerang in Poland, dated to roughly 42,000 years ago, suggests early Europeans developed complex symbolic tools independently during the Early Aurignacian, reshaping understanding of cognitive evolution.

Shortly after the excavation began, the objects began to sprout from the earth. Among the findings was what appeared to be a 72 centimetres long boomeran made from a mammoth …
