Charred bones are better preserved and are therefore relatively more reliable.

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.

For example, if the cultural contents of the lower deposit are Mauryan in character, appropriately this deposit may be assigned a date between 400-200 B. Similarly, if the cultural equipment of the upper deposit are of the Sunga period, this deposit has to placed between 200-73 B. Quite often, the archaeologist decided the change of stratum on the basis of the feed of the deposit.

At that time the radioactive disintegration takes over in an uncompensated manner. only half the C-14 will remain after the half-life period.

In the disintegration process the Carbon-14 returns to nitrogen emitting a beta particle in the process.

Astronomical data have been applied in the study of geological ice ages by calculating the curves for major fluctuation of solar radiation.

Consequently, the chronology worked out for the geological deposits helped in dating the prehistoric tools found in these deposits. There are certain antiquities and potteries which by themselves have acquired a dating value.

This dating method is also known as Archaeological Dating or Historical Chronology. These methods were relied on especially prior to the introduction of scientific methods of dating.

But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating.

The types and forms or shape of these pots and also the antiquities under go evolutionary changes in cource of time, It is further assumed that all living animals derive body material from the plant kingdom, and also exhibit the same proportion of C-14 material.

Therefore as soon as the organism dies no further radiocarbon is added.

For example, beads closely resembling those from the temple repositories at Cnoss and dating from C.1600 B.
