When these events are well dated, geochronology could be considered a reliable calibrated relative dating technique.Associated evidence may be changes in the frequency of plant species measured by pollen count and other kinds of paleoecology evidence.Calibrated relative methods could be considered to be somewhere between ordinary relative methods and radiometric methods in terms of their ability to produce dates that closely approximate the actual date of a sample.Amino acid racemization and paleomagnetic dating are generally considered to be either chronometric or calibrated relative methods.The rate at which fission tracks occur is related to the half-life of uranium-238, which is a relative dating method based on the fact that bones buried in the ground progressively lose nitrogen and gain fluorine and other trace elements.The rate at which these changes occur depends on the local environment.based on the fact that amino acids progressively change to mirror image forms following the death of an organism--i.e., from L-amino acid to D-amino acid forms.Aspartic acid in organic samples is commonly used for this dating technique.things that are intentionally made according to a cultural pattern or inadvertently modified as a result of culturally patterned behavior.

The ratios of these two forms of carbon vary directly with the age of the material.

the most commonly used calendar system in the world today.

It is based on the older Julian calendar of the late Roman Empire but more accurately corresponds to the solar year of 365.2422 days. This is inaccurate by approximately 11 minutes a year.

In the Julian system, a day is added to the end of February every 4 years.

In the Gregorian system a year is a leap year if it is divisible by 4 unless it is divisible by 100 but not by 400.

If two bones from the same site have markedly different amounts of nitrogen and fluorine, it is a strong indication that they did not come from the same time period.
