Radiocarbon dating human bones local internet dating services
Considering that collagen contains about 40–45% carbon, 250 mg of bone are necessary to provide enough carbon for a regular-sized graphite target of 1 mg.For well-preserved bone (20–25% collagen), the sample size decreases to about 10 mg.
It should be noted that it is not the artefact that is being dated, it is the soot, ash or charring.
However, careful examination of the literature suggests that attempts at dating samples smaller than 60 mg are rare.
Regarding small vertebrates, only two case studies were found: the Late Prehistoric dispersal of Polynesians to New Zealand was dated using the commensal Pacific rat as a proxy. ivory, bone or antler), progress in sample pretreatments using ultrafiltration.
After this the amount of carbon-14 present in the sample is too small to be measured precisely.
Carbon-14 can not be used to measure the age of very young specimens as the difference between the amount of carbon-12 and carbon-14 will not be sufficient to be detected.
