In this paper we present the results of an investigation where we try to date pottery from an Early to Middle Iron Age site in eastern middle Sweden. An overarching aim is to contribute to the discussion of the timing of a change inland-use and settlement structure that occurs in the middle of the first millennium CE. Selecting a well preserved site for excavation, we performed both plantmacrofossil analyses of soil-samples and lipid residue analyses on pottery. Both archaeobotanical materials as well as lipid extracts were subjected to radiocarbondating. The results show that the radiocarbon dating of purified lipid extractsfrom prehistoric pottery is possible.
