OK now you guys have taken it to the scientific level LOL just when ya all thought it was beat beyond beat it is what it is.........
The Maitreaux site is important in relation to understanding large, thin, bifacial, laurel leaf blade production (known as “Solutrean type J”). These blades are rare and generally attributed to middle Solutrean, although here they seem to extend into the late phase. Analysis suggests classic bifacial reduction to leave the centre portion of the blank was the norm, but the previously unknown asymmetric reduction technique was first identified here. That piece I posted was not being worked to a centre-line ridge, it was being asymmetrically reduced, for which the advantages to the knapper are: rapid thinning, better flaking angles, larger margins for eventual error correction, easier elimination of internal defects and less need for continuous biface plane adjustment. It’s a particularly valuable technique for nodules which have a coarse internal zone and a high-quality sub-cortical zone, as is the case at Maîtreaux and other sites in the vicinity.
Maitreaux has yielded over 60,000 lithics but the vast majority of finds are unfinished. Final shaping flakes are rare on the site. Bradley has divided the production sequence into distinct phases, simplified as:
1. Testing and preforming of carefully selected nodules (procured elsewhere), accomplished mainly by mineral hammer percussion.
2. Reduction carried out on the site by organic percussion, simultaneously thinning and shaping the pieces.
3. Systematic export of the pieces for finishing elsewhere, sometimes including pressure flaking towards the end of the sequence.
There is a strong suspicion that so called “early/middle/late” large Solutrean laurel leaves may well be more indicative of different stages in the production sequence:
