Basing on this principle, the cultural assemblages found in different layers can be assigned a chronological personality. In practice it is found that the mounds are disturbed9 by all sorts of pits and dumps.

The assumption is that both the people and the species that is now an index fossil must have lived at about the same of a relative dating method that measures somewhat irregular occurring natural phenomena that have been cross-dated with at least one chronometric technique so that the dates are somewhat comparable from sites in one region to another.Even when the absolute dates are available, we have to supplement the information with relative dating.The various methods of relative dating are; This method depends on the common observation that the height of the habitational area increases as the people continue to live at the same place.Even the process of preparing a specimen for racemic dating can affect the D/L ratio.For example, consider that neither the structure nor the proportion of the amino acids used for dating coral, ostrich eggshell, or snail shells is known. Using"Amino acid dating cannot obtain the age of the material purely from the data itself.a research instrument primarily used in physics to accelerate streams of charged subnuclear particles to high velocities in order to sort and analyze them.

This technique is now also used to count carbon isotope atoms for radiocarbon dating.Archeologists who worked on the 1960s surveys developed the chronology of both the production of rock art as well as the order in which different symbols were created.By associating symbols with sites that could be dated, archeologists believed that most Coso rock art was produced during the last few thousand years with a marked flurry of production about one thousand years ago.After years of analysis using a variety of techniques, archeologists have proposed two theories to explain the phenomenon.One centers on ecological change and the threat of dwindling resources.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.
