What is Radiocarbon Dating? Radiocarbon dating is a method of what is known as “Absolute Dating”. Despite the name, it does not give an absolute date of organic material - but an approximate age, usually within a range of a few years either way. The other method is “Relative Dating” which gives an order of events without giving an exact age (1): typically artefact typology or the study.

Radiometric dating of Mesozoic strata using radioisotopes other than radiocarbon (e.g., U/ Pb, U/ Pb, 87 Rb/ 86 Sr, 40 K/ 40 Ar, 40 Ar/ 39 Ar) shows that the sediments that entomb Mesozoic fossils are 65– million years old (Gradstein et al., ), which means that the fossils that they entomb are that old – far too old for any measurable amount of original radiocarbon to remain in the fossils. So how is it that measurable radiocarbon Author: Philip J. Senter.
