LEF 1/4 + PR	1.21	KIA28881	sea weed	−15.9	1965 ± 25	*387−472 AD	*349−533 AD

Notes: unid. plant remains—unidentified plant remains. C.g.—Cerastoderma glaucum. Lab. No.—laboratory number, University of Kiel (KIA), University of California, Irvine (UCI). *—marine reservoir correction with 400 years of reservoir age. “#”—calibration yielded several possible age intervals because of multiple intersections with the calibration curve; the oldest and youngest possible ages are depicted.
