Analysis of stone tools excavated 40 years ago

Just today, I've got this journal.

Shibutani, A. 2014. Starch residue analysis of stone tools excavated from the 6th survey of the Nakabyo site. Shimousa Kokogaku 23: 160-161.

Analysing materials excavated in very recent years can avoid any contaminated problems at the lowest possible level. This becomes one of my good experiences because I have conducted starch residue analyses of "all of materials on any conditions".
