14C results obtained for the samples from Kalapodi, Lefkandi and Corinth with ceramic phase, laboratory number, material identification, context description, sample ID, 14C age in yr BP, calibrated ranges for ±1σ and ±2σ, and ‰ δ13C.

The samples are ordered according to the relative chronological sequence. LH IIIC: Late Helladic IIIC; SM: Sub-Mycenaean; EPG: Early Proto-Geometric; MPG: Middle Proto-Geometric; LPG: Late Proto-Geometric; SPG: Sub-Proto-Geometric; EG: Early Geometric; MG: Middle Geometric; LG: Late Geometric;*: the date is the average of multiple measurements on the same sample (the number of measurements is indicated between brackets);a: RTK6372 and RTK6373 are parts of the same assemblage of seeds, and therefore dates were averaged;b: RTK6374 and RTK6375 are parts of the same assemblage of seeds, and therefore dates were averaged.All the charred seeds come from clusters. References for published contexts are included within the “Context” column; all the other contexts are yet unpublished. δ13C values were obtained using an isotope ratio mass spectrometer.
