Calibration for Archaeological and Environmental Terrestrial Samples in the Time Range 26–50 ka cal BP

Christopher Bronk Ramsey, Marian Scott, Hans van der Plicht


For the older part of the radiocarbon dating range, the IntCal13 curve provides the "state of the art" for terrestrial calibration based on all available data. It is constructed from different records each of which by itself could be used as a "comparison tool," depending on the research objectives. This paper discusses the pros and cons of different approaches that can be taken when using 14C dates from this time range where there is poorer agreement between the underlying data sets. The discussion is illustrated with example calibrations against IntCal09, IntCal13, and comparisons to the Suigestu record. It is aimed at users of terrestrial 14C dates, in particular Upper Paleolithic archaeologists, and those working with environmental terrestrial materials in the same time range.
