The importance of shell: Redating of the To’aga site (Ofu Island, Manu'a) and a revised chronology for the Lapita to Polynesian Plainware transition in Tonga and Sāmoa
Fig 5
Bayesian sequence model for the To’aga site.
This model uses a ΔR value of -160±48 14C years for samples that date between 2600 and 2250 cal BP (i.e., “Main Excavation Layer IIA-C”) and -48±82 14C years for earlier phases. The period between 2600 and 2250 cal BP is indicated by the grey bar. 68% and 95% error margins are indicated by bars under each age distribution. The notation [O:2/5] indicates a 2% posterior probability of being an outlier in the model.
