Relative Dating
Paleontologists use fossils to determine the relative ages of rocks. Due to evolution the fossil assemblage in rocks changes over time and the different assemblages can therfore be used to place the rocks in which an assemblage is found in its place in the evolutionary sequence.
It alows one to understand and study past life and environments (habitats which supported that life or helped preserve or make the fossils) and provides a tile sequence which allows relative dating of fossiliferous rocks.

Identical pattern of rocks and fossils in the southern hemisphere
It is an imaginary column where are the ages of rocks sit on top of one another in their proper age sequence, oldest at the base and youngest at the top. An ideal sequence of rock layers that contains all the known fossils and rocks whith each sequence is given its name.
