Current accepted conventions for citing radiocarbon dates are set out by A.R. Millard in Radiocarbon 56: 555–59 (DOI: http://dx.doi.org/10.2458/56.17455). For every date that is quoted in Antiquity, whether in a table or in the text of an article, we ask authors to provide the following details wherever possible:
In the case of calibrated or modelled dates, authors are also asked to specify
The preferred Antiquity convention is for calibration using the OxCal program (available online at https://c14.arch.ox.ac.uk/oxcal.html) with calibrated dates quoted at 95.4% ranges.
Please include in your article any references relating to the software version and calibration curve used. Example:
A human metacarpal gave a date of 5439±34 BP (OxA-14953: 4347–4242 BC at 95.4%; date modelled in OxCal v.4.2, using IntCal13 calibration curve (Bronk Ramsey 2009; Reimer et al. 2013)).
