Summary

Analyses of organic residues on ceramics complement other types of archaeological evidence used to characterize diets of populations colonizing and adapting to Caribbean Islands. Gas Chromatography - Mass Spectrometry (GC-MS) is used to identify compounds sampled from 20 sherds excavated from two households (the Goddard Site 200 B.C. - A.D. 300 and Chancery Lane Site A.D. 800-1500). Measurable peaks of fatty acid residues are present on six samples from the Goddard Site. Smaller traces of fatty acids are present on Chancery Lane sherds. A comparison is made of fatty acids by type of sherd (rim/body, size, decoration), and visible types of residue (black and/or white substances). The specific composition of fatty acids present may help identify garden produce (maize, cassava and/or palm lipids) and animal resources such as fish and turtle. Results contribute to the growing field of molecular archaeology and environmental archaeology in the Caribbean.
