Survey in Okayama

On November 22 (Tue), I took residue samples for starch residue analysis at the Okayama University.

These samples were from stone tools in this year's survey of the Iwabushi site and from stone tools in the 2nd and 4th excavations of the Igozori site. Both of them were the Jomon sites around the Daisen Mt.

All of stone tools were already washed, but I've got a sediment sample near a ground stone of the Iwabushi site.

As my first step, I need to check any starch granules from these sampled stones.
