This technique begins with the identification of the bones.
If the skull is found, then the technique proceeds with recording its dimensions.

The principle of superposition is the core principle used in this method.
The amount of fluorine in the fossils thus increases.
If two fossils belong to the same strata, then they are assumed to have the same amount of nitrogen and fluorine.
