Bayesian model of the radiocarbon dates from Riwi.

<p>Dates have been calibrated against SHCal13 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0160123#pone.0160123.ref030" target="_blank">30</a>] and modelled in OxCal v.4.2 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0160123#pone.0160123.ref031" target="_blank">31</a>]. Pale probability distributions represent the calibrated, unmodelled date, whilst dark grey distributions represent the modelled date. The two brackets beneath the distributions represent the 68.2% and 95.4% probability ranges. Prior and posterior outlier probabilities are given in brackets following the sample name in the form [O: posterior/prior]. A ‘?’ implies the date was not included in the model.
