The term "Mousterian" is used to describe a specific type of stone tool technology associated with Neanderthals and their relatives. However, there are a number of synonyms that can be used to refer to this period and its artifacts. For example, some archaeologists may use the term "Levallois industry" to describe stone tools made using a particular flaking technique. Others may refer to the "Middle Paleolithic" period, which is roughly equivalent to the time when Mousterian technology was in use. Ultimately, the choice of terminology may depend on a number of factors, including regional variations in artifact assemblages and the specific research questions being addressed.
