1	Aquatic Resources in Foodcrusts: Identification and Implication Heron, Carl P., Craig, O.E. January 2015 (has links) No / Foodcrusts, the charred surface deposits on pottery vessel surfaces, provide a rich source of data regarding container function. This article reviews recent applications focusing on the detection of aquatic resources (marine and freshwater) in pottery vessels using a range of analytical approaches including bulk isotope measurements of carbon and nitrogen, lipid biomarker analysis, and compound-specific carbon isotope determinations. Such data can help to evaluate the presence of reservoir effects when undertaking radiocarbon dating of foodcrust samples. In particular, molecular and isotopic analysis can aid in the selection of suitable candidates for C-14 where it can be demonstrated that aquatic resources are unlikely to contribute to the residue. Prospects for compound-specific C-14 analysis of lipids in foodcrusts and ceramic-absorbed residues are also discussed.

2	Illuminating the Late Mesolithic: residue analysis of 'blubber' lamps from Northern Europe Heron, Carl P., Andersen, S.H., Fischer, Anders, Glykou, A., Hartz, S., Saul, H., Steele, Valerie J., Craig, O.E. January 2013 (has links) No / Shallow oval bowls used on the Baltic coast in the Mesolithic have been suggested as oil lamps, burning animal fat. Here researchers confirm the use of four coastal examples as lamps burning blubber-the fat of marine animals, while an inland example burned fat from terrestrial mammals or freshwater aquatics-perhaps eels. The authors use a combination of lipid biomarker and bulk and single-compound carbon isotope analysis to indicate the origin of the residues in these vessels.
