Yesterday, I presented "Starch residue analysis of archaeological ground stones" as my initial report at the Research Center for West Asian Civilization in the University of Tsukuba.
In last September, 2013, I conducted starch residue analysis of ground stones found from the Hasankeyf Höyük site in Turkey, and I reported my initial results. My surveys were as the following.http://japanese-archaeobotany.blogspot.jp/2013/09/1st-day-of-my-survey-in-turkey.html
Compared with case studies of ground stones in the Jomon period, Japan, the number of starch granules is fewer, but I have to examine various things in terms of sampling methods including contaminated problems and candidate plan species of starch granules in further works. Based on these results, I will join in the forthcoming survey this year as well.
What were many stone mortars and pestles found from the site used for? From starch residue works, I would get any evidences.
