The dates were performed at the Oxford Radiocarbon Accelerator Unit and at the Liebniz Laboratory of the Christian Albrechts Universität of Kiel on the bone collagen of two Mesolithic humans from Grotta d’Oriente. The dates were calibrated with Oxcal 4.1. [48] using the IntCal09 calibration curve [49]. The date on sample S-EVA 2800 (KIA-36050) had previously been reported by D’Amore et al. [67]. The age obtained by modelling the AMS radiocarbon dates from the three rib fragments of Oriente B (S-EVA 2799-2801), however, represents a more accurate estimate of the chronology of this individual. The calibration of the 14C dates done by taking into account the potential estimated proportions of marine foods consumed by Oriente × (<20%) and Oriente B (<10%), and the marine reservoir correction for Sicily [82], produces respectively calendar ages of 9620 (p.95.4%) 9480 cal. BP and 10580 (95.4%) 10420 cal. BP. These age ranges are only marginally more recent than those shown in the table, calculated assuming fully terrestrial diets.
