Advantages of using relative dating

A calibration curve can be produced by measuring standard solutions of known fluoride concentration.

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.Fluoride dating works best when bones of similar density are compared.Therefore, it is rarely possible to mix results from skeletal elements with widely differing densities (i.e., femur cortical bone versus vertebral fragments), or to compare juveniles with adults, or to compare bones from very large or very small mammals.We require at least 0.1 gram of bone simply for handling convenience.

The actual measurements will only consume about 15 mg.

For faunal specimens, we recommend long bone fragments, which are usually very abundant.For humans, either ribs or cortical bone fragments both give good results, as long as one type of bone is consistently used.A desciption of the method is given in: Schurr, Mark R.1989.Fluoride dating of prehistoric bones by ion selective electrode. It can be used to determine the relative dates of faunal materials.The resulting fluor-apatite is more stable than the original form, thus the fluoride content of a bone will increase over time if it is exposed to a solution containing fluoride ions.
