Absolute dating examples

The requirement of identical burial conditions means that fluoride dating works best when it is applied within a single site with little variation in soil chemistry.

For example if you have a fossil trilobite and it was found in the Wheeler Formation.Over time, buried bones pick up fluoride ions from soil moisture or exposure to groundwater.Older specimens have higher fluoride contents than younger ones when burial conditions are identical.Fluoride (or fluorine) dating is a relative dating method that can be used to date archaeological bone.As a relative dating method, it can determine the relative age of specimens, but cannot provide a calendrical date unless the fluoride chronology is calibrated with an absolute dating method.
