Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.

It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

All animals in the food chain, including carnivores, get their carbon indirectly from plant material, even if it is by eating animals which themselves eat plants.

The net effect of this is that all living organisms have the same radiocarbon to stable carbon ratio as the atmosphere.

It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe.

Further complications arise when the carbon in a sample has not taken a straightforward route from the atmosphere to the organism and thence to the measured sample.

When it comes to dating archaeological samples, several timescale problems arise.

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.

Relative dating stems from the idea that something is younger or older relative to something else.
