Mousterian (m -stîr'ē-ən) Pronunciation Key
Relating to a Middle Paleolithic tool culture that succeeded the Acheulian, ending around 35,000 years ago and traditionally associated with Neanderthals. While Mousterian tools show improvements in stone-flaking techniques over Acheulian tools, they remain largely unchanged over long periods of time and show little of the rapid innovation and specialization that characterize tool cultures of the Upper Paleolithic associated with modern humans. |
