Answer:
Fossils give information about the time periods in which organisms lived in the past.
Explanation:
Fossil records tells us the story of past like how old the earth is, how various plants and animals are being related to each other. They are generally seen in the surface layer of the Earth. The older ones are present in deeper layers than that of the younger ones. This is the best example that can be considered for continuous evolution. It is being used for the reconstruction of the evolutionary history. Again they are of three types, mold fossil(impression made in the substrate i.e. the negatie image of organism) cast fossils ( when the mold is filled), trace fossil ( burrows, footprints.)
