According to LaFille (and supplemented by work of
Laville, Assassi, Turq, and Van Campo and Bouchud ) the roughly
two-meter stratigraphic sequence, from bottom to top, is as follows:
· Beds I-II, noted by the presence of red and roe deer, contains a Denticulate Mousterian assemblage.
· Bed III, which represents the start of the Pleniglacial (OIS 4), contains horse, bovids, and reindeer. The industry continues with Denticulate Mousterian.
· Beds IV-VII, which presumably are still within OIS 4 (and with still increasing amounts of reindeer), marks the beginning of a succession of Typical Mousterian assemblages, all of them relatively rich in scrapers.
· Beds VIII-XII, still within OIS 4 or perhaps, in the upper of these levels, at the beginning of OIS 3. This is the part of the sequence that contains a Quina Mousterian industry.
· Following a disturbed level, the top of the sequence, Bed XIV, contains a mix of Chatelperronian, Aurignacian, and Medieval.
