Abstract: Prior to the production of pottery 3000 years ago, humans would often carve large bowls out of rock, usually soapstone. Samples of such an artifact from the Thrash site, a Late Archaic period (3,000-1000B.P,) site in Pike Country, Alabama, have been subjected to a three step process for identifying fatty acids, the primary substance of foodstuffs. We used gas chromatography/mass spectroscopy (GC/MS) to analyze samples from the artifact along with samples of natural soapstone. The presence of different fatty acids can provide information about prehistoric dietary habits, whether from fish, mammals and/or plants. For the analysis, however, the fatty acids must be converted (derivatized) to fatty acid methyl esters (FAMEs). We used a method that converts triacylglycerides into FAMES in a one step process. These fatty acids will be correlated to a range of plants and animals that came into an extended period of contact with the artifact.
