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 of the sequence of the evolution of fossils.

Stone and metal cannot be dated but pottery may be dated through surviving residue such as food particles or paint that uses organic material (8).
There are a number of ways to enter into a career in studying radiocarbon dating.

The overlapping nature of the tree records means this is the most accurate record we have.
