One of the most widely used and well-known absolute dating techniques is carbon or radiocarbon dating, which is used to date organic remains. They can be dated according to the geological stratum in which they are found, or by carbon dating, or by other clues found either in the fossil or in the site where the fossil was found. Does radioactive dating tell the relative age of rocks?
In some areas of the world, it is possible to date wood back a few thousand years, or even many thousands. Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year.
