If not carbon dating then what

For this reason, it’s preferable to date objects using multiple methods, rather than relying on one single test.Carbon dating is reliable within certain parameters but certainly not infallible.For radiocarbon dating to be possible, the material must once have been part of a living organism.

By measuring the ratio, R, in a sample we can then calculate the age of the sample: T = -8033 ln(R/A) Both of these complications are dealt with by calibration of the radiocarbon dates against material of known age.The dating process is always designed to try to extract the carbon from a sample which is most representative of the original organism.In general it is always better to date a properly identified single entity (such as a cereal grain or an identified bone) rather than a mixture of unidentified organic remains.This makes the results subject to the researchers’ assumptions about those objects.If the spear head is dated using animal bones nearby, the accuracy of the results is entirely dependent on the assumed link between the spear head and the animal.
