* The original sample was too small for a 13/12C ratio measurement. However, a ratio including both natural and laboratory effects was measured during the 14C detection to derive a Conventional Radiocarbon Age, suitable for applicable calendar calibration.

** Reported result indicates an age of post 0 BP, indicating the material was living within the last 50 years. This sample was not considered in analyses.
