Amino Acid Racemisation (AAR) is a useful comparative dating method with great potential, but it introduces problems of calibration and the requirement of an intimate knowledge of the palaeoenvironmental conditions of the bone deposition site.
Table-1: The hominid fossil record is extremely fragmentary, and chronology is essential in unravelling the complex record of human development.
First, it is because varve accumulation occurs only to glacial areas of the world.
Fission track dating is based upon the fact that over geological time spontaneous fission of uranium-238 impurities produces minute sub- microscopic damage trails in the most insulating solids, both long period of time.It has been used in Baltic area, North America, South America and Africa.In North America, Ernst Antevs has made several attempts to relate Pleistocene geological formations in the American Southwest to events that produced varves in the northern parts of North America.The sequence of development of culture or the relationship between events that represent culture can be established only when events can be placed in proper time.Chronology, the study of events in time frame, is hence the central theme of archaeologist, like the geologist who deals with the story of earth history.
