The association of faunal, climatic and archaeological information derived from the site can be the same as the specimen. To determine contemporaneity evidence is required to show there is no unnatural disturbance of the specimen, no intrusive burial, and no derivation from older deposits.This requires photographs in situ and stratigraphic drawings. Buried bone accumulates fluorine by a rate determined by local conditions.The fluorine becomes fixed in the bone and is not readily removed which provides the method. dating fossil mankind requires correct placing in the Pleistocene and Holocene periods.With regard to uranium mineral phosphates, including bones, all contain uranium. Also the determination of morphological evidence in terms of the hominid phylogeny.Absolute dating implies chronometry and is the oldest method in use.The upper atmosphere, nitrogen, and the bombard of cosmic radiation results in a known proportion of radioactive carbon which is incorporated into atmospheric carbon dioxide.Contemporaneity is not always justifiable due to mankind’s long established practices of burying the dead.
Secondly, the remains have to have contemporaneity with deposits.Either from the same site or some other area if they have been preserved under comparable conditions. Fats, protein (collagen) and the fatty composition are lost quite rapidly. Under some conditions, such as permanently frozen soil or exclusion of air and bacteria, the protein may persist for tens of thousands of years.As soon as bones are buried their composition is subject to chemical changes, some of which are slow, some fairly rapid. The appearance and texture of bone is not a reliable guide to how much organic matter it contains.These are leached out or retained according to local conditions. Alteration of the phosphatic material of which bones are mainly composed is hydroxyapatite.The addition of new mineral matter, such as lime or iron oxide, changes the latter and leads to an increase in weight.
Nitrogen decreases in buried bone and affects nitrogen concentrations. With regard to relative dating Comparative geology includes correlations with soil pollen content.
