1-3 (3 Records)
Four ceramic rim sherds and a chitho from the Forks Site (DlLg-33/08A), a prehistoric riverine trade loci, located in downtown Winnipeg, Manitoba, Canada, were submitted for ceramic and organic residue analysis. In addition, a grinder/hammer stone, a biface, and a retouched flake were examined for protein residue. The grinder/hammer stone was also tested for organic residues, as was visible residue from a limestone ochre bowl. X-Ray Diffraction (XRD) will be used to verify the residue on the...
PHYTOLITH, STARCH, PROTEIN RESIDUE (CIEP), ORGANIC RESIDUE (FTIR), AND XRD ANALYSIS OF SAMPLES FROM THE METZ SITE (33ER557) AND THE HECKLEMAN SITE (33ER14), OHIO (2011)
Sherds from two ceramic vessels with visible residue from the Metz site (33ER557) were submitted for phytolith, starch, organic residue (FTIR), and x-ray diffraction (XRD) analysis. Two celts were submitted for phytolith, starch, protein residue (CIEP), and FTIR analysis. Phytolith, starch, protein residue, and organic residue analyses were undertaken to better understand what foods may have been prepared or processed using these items. XRD analysis of the exterior slip coating provides...
POLLEN, PHYTOLITH, STARCH, AND PROTEIN ANALYSIS OF STONE ARTIFACTS FROM PAISLEY CAVES (35LK3400), OREGON (2011)
Six stone artifacts and a wash of a large metate (a liquid sample) were submitted for pollen, starch, phytolith, protein, and XRD analyses from the Paisley 5 Mile Point Caves, Oregon. Previous work by PaleoResearch and other researchers has identified the presence of a variety of mammal and fish protein residue and DNA at the Paisley Caves. Because of the age of this site, the suite of protein residue antisera used to test these artifacts included elephant, camel, and horse, representing...
