On February 7 and 8, I took residue samples from stone tools found from the Nakanoyama site in Mie Prefecture.
In my study, this survey is just the 2nd survey of this site. Here is the former. Together with this survey results, my approaches will be published in the excavation report.
As the former analysis, I found very good preserved starch granules. How many starch granules can I extract from residue samples this time?
