CHLARA001	NZA 26115	Chicken bone	622 ± 35 BP	AD 1304–1424	−20.9	ND	ND
CHLARA003	NZA 28271	Chicken bone	510 ± 30 BP	AD 1427–1459	−19.85	2.6	2.16
CHLARA004	NZA 28272	Chicken bone	506 ± 30 BP	AD 1426–1457	−19.45	3.5	ND
EA1-001	UCTL 1617	Pottery	650 ± 65 BP	AD 1285–1415				1.14 ± 0.11	1.76 × 10−3
EA1-002	UCTL 1618	Pottery	610 ± 55 BP	AD 1335–1445				0.96 ± 0.11	1.58 × 10−3

All ¹⁴C dates were calibrated with CALIB (5) by using the Southern Hemisphere atmospheric curve (6). P, Paleodose; D, dose rate.
