Both plants and animals exchange carbon with their environment until they die. Then after another 5, years half of the remaining parent isotope will have decayed. This happens at known rates. As potassium decays, it turns into argon. This can often be complicated by the fact that geological forces can cause faulting and tilting of rocks. Researchers can first apply an absolute dating method to the layer. Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died. This process frees electrons within minerals that remain caught within the item. The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results. These techniques are accurate only for material ranging from a few thousand to , years old — some researchers argue the accuracy diminishes significantly after , years. In some areas of the world, it is possible to date wood back a few thousand years, or even many thousands. Currently, the maximum for fully anchored chronologies is a little over 11, years from present.

    While K-Ar dating requires destroying large samples to measure potassium and argon levels separately, Ar-Ar dating can analyze both at once with a single, smaller sample. If the fossil you are trying to date occurs alongside one of these index fossils, then the fossil you are dating must fall into the age range of the index fossil.
