The possibility of obtaining molecular information from lipid residues associated with archaeological pottery has dramatically increased the potential for deriving new information on the use of ancient vessels and the commodities processed therein. Motivated by the high proportion of the archaeological potsherds that have been shown to contain animal fats, a new approach involving compound specific stable isotope analysis of remnant fats has been developed to retrieve information which will allow new insights into animal exploitation, dietary preferences and vessel use amongst prehistoric peoples. The new approach uses the d13C values of the major saturated fatty acid (C16:0 and C18:0) determined by gas chromatography combustion - isotope ratio mass spectrometry (GC-C-IRMS) to characterise the origins of animal fat recovered from archaeological pottery.

Danes je mogoče dobiti molekularne podatke iz lipidov, ohranjenih na arheološki keramiki, kar je močno povečalo obseg informacij o uporabi starodavnih posod in njihovi vsebini. Ker se je za velik del arheoloških fragmentov izkazalo, da so vsebovali živalske maščobe, so razvili nov način raziskav, ki je vseboval sestavljene analize specifičnih stabilnih izotopov v živalskih ostankih. S tem dobimo podatke, ki nam dajo nov pogled na izrabo živali, način prehranjevanja in uporabo posod pri prazgodovinskih ljudeh. Nov pristop uporablja d13C vrednosti najbolj nasičene maščobne kisline (C16:0 in C18:0), ki jih določimo s posebno masno spektrometrijo (gas-chromatography-combustion-isotope ratio mass spectrometry: GC-C-IRMS), dadoločimo izvor živalskih maščob na arheološki keramiki.

Keywords:arheologija, keramika, živalske maščobe, organski ostanki, spektrometrija
