Pottery is one of the most commonly recovered artefacts from archaeological sites. Despite more than a century of relative dating based on typology and seriation 1 , accurate dating of pottery using the radiocarbon dating method has proven extremely challenging owing to the limited survival of organic temper and unreliability of visible residues Here we report a method to directly date archaeological pottery based on accelerator mass spectrometry analysis of 14 C in absorbed food residues using palmitic C and stearic C fatty acids purified by preparative gas chromatography We present accurate compound-specific radiocarbon determinations of lipids extracted from pottery vessels, which were rigorously evaluated by comparison with dendrochronological dates 9,10 and inclusion in site and regional chronologies that contained previously determined radiocarbon dates on other materials Notably, the compound-specific dates from each of the C and C fatty acids in pottery vessels provide an internal quality control of the results 6 and are entirely compatible with dates for other commonly dated materials.

With Zoom dating, there are more clear boundaries and consent, whereas IRL, things can be a little bit more coercive. We really hit it off—more so than I have with anyone in real life in probably more than two years. It seems like communicating via phone and FaceTime before actually meeting has allowed us to find common ground and interests before anything physical takes place.
