PROTEIN, PHYTOLITH, AND STARCH ANALYSIS OF TWO SEMI-LUNAR KNIVES

Semi-lunar pre-contact stone tools, recovered from two sites (Walker Point Site, Bluff Section, RI-653 and the Susquetonscut Brook Pre-Contract Site 4, 71-033), were submitted for protein residue analysis as part of a research project studying their use. The sites are situated along the Seekonk River in Rhode Island and above Susquetonscut Brook in the Yantic River drainage in eastern Connecticut.

半月形前接触时期石器（Semi-lunar pre-contact stone tools）作为研究其使用功能的科研项目的组成部分，被送检以开展蛋白质残留物分析。该类石器出土自两处遗址：沃克角遗址（断崖段，编号RI-653）与萨斯奎顿斯卡特溪前接触遗址4号（编号71-033）。上述两处遗址分别坐落于罗德岛州西孔科德河（Seekonk River）沿岸，以及康涅狄格州东部扬蒂克河（Yantic River）流域内的萨斯奎顿斯卡特溪上游区域。
