PHYTOLITH AND STARCH ANALYSIS OF TWO GRINDING STONE RESIDUE WASHES FROM NORTHERN CHILE (2011)
DOCUMENT Full-Text Chad Yost.

Two grinding stones from northern Chile were washed for phytolith and starch remains. The washes were conducted in Chile and the resulting residue was dried and sent to PaleoResearch Institute for analysis. The goal of the analysis was to identify plant opal phytoliths and starch grains that may be derived from plant material processed with these tools.
