That is where, I hope, PalaeoChron will make a contribution. How you can help Radiocarbon dating Radiocarbon dating is a technique that measures the concentration of naturally occurring radioactive carbon 14C. AMS radiocarbon dating of individual fragments of charcoal from excavated archaeological deposits, bone fragments from ritual sites and organic materials from pollen sequences will also be undertaken. The best way to establish the age of rock art is to combine radiocarbon dates with other dating evidence, such as stratigraphic sequences. With all these sample types it is important that samples are screened and specialized pretreatments applied to ensure the accuracy of the dates.
