Carbon Dating - Dendrochronology As we've already seen, in order for Carbon dating to work we need to know what the C-12 to C-14 ratio was at the time of a specimen's death.If the ratio has fluctuated throughout the unobservable past (and we can be sure that it has), how can we determine what the ratio was during the lifetime of a specimen that lived and died before we first began measuring the ratio?

Before this, their ancestors would have a recognisable tree form, believed to be that of a giant type of fern that began the process of developing a woody stem.Naturally, the outer rings represent the youngest years of the tree and you may notice that not all rings are uniform - some are thinner, some thicker, some light and some dark.These represent growth patterns that reflect the conditions of the season or the year (4) and it is these rings on which the entire study of dendrochronology is based.By carbon dating a piece of wood which has also been dated by counting its annual tree-rings, scientists can create a table by which they can convert the questionable Carbon-14 years into true calendar years.This is how it works: scientists begin with a living tree or dead wood specimen which can be accurately dated by some reliable means.
