It concentrates mainly on the placement of the strata as well as its chronological sequence.The principle of superposition is the core principle used in this method.

However, this is mainly applicable to an undisturbed arrangement of rocks.

Most of the rock arrangements are disturbed by natural forces, such as wind and water, which result in unconformity in the sequence of rocks.

If an animal fossil is found, and the time during which it lived is known, it helps us understand the time period of any other fossil found in the same strata.

Animals evolve rapidly, and these evolution's are reflected by the variations in their bones or teeth.

Further on, this data is compared with the standard data to establish the age of the fossil.

Archeology refers to the study of history of mankind by excavating ancient sites.

The principle of superposition states that the layer which lies at the bottom is older than the one on top of it.

In stratigraphic relative dating, the succession of layers can be seen as the timeline of its formation or deposition.

Most of the nitrogen contained in these fossils gets depleted progressively.
