Ghost Knapper:
Why do you think the flake crumbled? the way it did? Im not surprised by the chalky area but the last section of the flake breaking into 3 pieces is intriguing.

AncientTech:
Ghostknapper,

I cannot give you a good answer.  I can only guess. 

Basically, you are looking at something that is outside the realm of known descriptions, and study.  It involves the combination of many different types of flintknapping forces, all with different types of attributes, all linked together in a process.   

The fragmentation might have to do with the thinness of the stone, coupled with really intense energy.  Again, that is a shot in the dark answer, at best.

Here are some similarly related flakes, that show less shatter, and that also tend to be thicker.  They are made in a prior stage, before the overshot stage, from the same umbrella technology.













I would have to lean towards thinness, and energy, as being the culprits. 

Another possibility could relate to the way that the force is delivered to the stone, or imparted into the stone, in terms of contact area.
