Neanderthals used rhinoceros teeth as percussion tools to sharpen stone implements like quartz and flint.
Experimental archaeology successfully replicated wear patterns found on teeth from sites like El Castillo and Pech-de-l’Azé II.
Research indicates a strategic preference for the teeth of older rhinoceros due to their flatter, more effective surface.
The study highlights the sophisticated technical understanding and material exploitation strategies of Neanderthal groups.
