The Quina variant is represented by a very high percentage of scrapers, from 50 to 58 percent. Many special scraper forms not present in the other Mousterian industries occur, including transverse scrapers, scrapers with bifacial retouch over the entire surface, simple thick scrapers, and limaces. The Quina index is high (14 to 30) which represents the percentage of total scrapers that are of the Quina type. There are a few end scrapers, very few handaxes, no backed knives, few denticulates, and numerous notched flakes. The flakes are short and thick. Levallois flakes occur in limited frequency but the industry is primarily non-Levallois in character. Most of the Neanderthal specimens from western Europe are associated with Quina implements.
The Ferrasie variant features a high scraper index comparable to that of Quina, with a low frequency of transverse scrapers. The Quina index is moderate (6 to 14). FHandaxes and backed knives are rare to absent. The Levallois index is high (14 to 30).
Dating of the Mousterian variants has been summarized by Laville (1973). He states that the Quina, Ferrasie, and Mousterian of Acheulean
Tradition industries were manufactured throughout the entire Wlirm I and Wurm II periods and therefore are not chronologically distinct as have been suggested by other authors (Fig. 7-7).
