Fossils are remains or impressions of organisms that lived in the remote past. Fossils provide the evidence that the present animal have originated from previously existing ones through the process of continuous evolution. Fossils can be used to reconstruct evolutionary history of an organism. The distribution pattern of fossils shows that the ancient fossils present in the bottom rocks are simple, while the most recent fossils found in the upper strata are more highly evolved. It means fossils form and become more and more complex as we proceed from earliest to recent rocks. It gives us an idea of time in history when different species were formed or became extinct. Fossil also help to trace the evolutionary history of some animals.

Fossil fuels are non renewable sources of energy. For eg. Petroleum, Coal,e.t.c. are some examples of fossil fuels. And they do not tell Us about any evolution.
