| Bordes had originally considered the industries of these
layers to be examples of Typical Mousterian, but
our analysis of the complete series shows that all of them are much
higher in scrapers than what was seen by Bordes, with “essential”
Scraper Indices higher than 55. Most
of the scrapers are single forms, followed by double and convergent types;
transverse scrapers are rare. There
is some Levallois (with average IL about 13 percent) and a relatively high
degree of faceting. As with
most of the Pech IV industries, the majority of the blanks exhibit uni-directional
preparation, followed by sub-radial and radial.
These various types of exterior scar patterns do not appear to be
related to the degree of core reduction, as was the case with the
Mousterian assemblage from Biache St.-Vaast.
There are moderate degrees of both core reduction and tool
production.
