Neanderthals Used Rhinoceros Teeth as Tools, New Study Suggests
A study published in the Journal of Human Evolution has revealed that Neanderthals used rhinoceros teeth as tools during the Middle Paleolithic period, approximately 300,000 to 40,000 years ago. Led by Alicia Sanz-Royo and colleagues from the Muséum National d'Histoire Naturelle in Paris, the research analyzed rhino teeth from caves in Spain and France, finding markings consistent with human activity. Dental microwear analysis confirmed these marks were made post-mortem, indicating the teeth were used as tools. The study suggests Neanderthals strategically chose older rhinos for their teeth, which were more worn and thus more useful as tools.
