Study Reveals Neanderthals Used Rhino Teeth as Tools
A recent study published in the Journal of Human Evolution suggests that Neanderthals used rhinoceros teeth as tools during the Middle Paleolithic period. Researchers found markings on fossilized rhino teeth in caves in Spain and France, indicating human activity. The study, led by Alicia Sanz-Royo, involved dental microwear analysis to confirm that the marks were made post-mortem. The hardness of rhino teeth, due to their high hydroxyapatite content, made them suitable for tool use. The study involved recreating Neanderthal tools from modern rhino teeth to test their utility.
