Radiocarbon dating - Wikipedia

Dendrochronology or tree-ring dating is the scientific method of dating tree rings also called growth rings to the exact year they were formed. As well as dating them this can give data for dendroclimatology , the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating , which always produces a range rather than an exact date. However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide. It also gives data on the timing of events and rates of change in the environment most prominently climate and also in wood found in archaeology or works of art and architecture, such as old panel paintings. It is also used as a check in radiocarbon dating to calibrate radiocarbon ages. New growth in trees occurs in a layer of cells near the bark.

Radiocarbon dating measurements produce ages in "radiocarbon years", which must be converted to calendar ages by a process called calibration. Willard Libby , the inventor of radiocarbon dating, pointed out as early as the possibility that the ratio might have varied over time. Discrepancies began to be noted between measured ages and known historical dates for artefacts, and it became clear that a correction would need to be applied to radiocarbon ages to obtain calendar dates.
