"Yet, none of these show examples of the purported 'Dogon' gneiss(or granite or diorite or whatever) beads. Such lack of evidence supporting your hypothesis pushing the manufacture of these beads into the second millenium, possibly post-15th century, possible even more recent?"

Not my remark at all!

What I said about The Jenne digs is that I think they include GLASS TRADE BEADS that date from as late as the 16th/17th Cs. Thereby extending the proposed time range by nearly 300 years. That, of course assumes that these beads were "from Jenne digs." Which I don't know to be a fact; but which has been claimed.

I have remarked nothing (repeat, nothing) about dating Dogon beads, because I haven't any idea how this would be pursued. And I remarked that I don't see any association between recovered Dogon beads that would bring Jenne beads into the discussion—which was predicated by you.

JDA.
