Neanderthals may have used the talons of white-tailed eagles to make jewelry 130,000 years ago, long before the appearance of modern humans in Europe, according to a new study published in PLOS One. At an archaeological site in Croatia, researchers discovered the talons, above, with notches and abrasions suggesting they had been made into necklaces or bracelets. Eagle talons may have had symbolic value to Neanderthals, the researchers said.
