When remains of living beings get buried into sediments and turn to fossils, the bacteria present in the soil breakdown the proteins and fats from the bones.
Biostratigraphy: Layers get deposited above one another, over time, and fossils get trapped in these layers.

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.
