Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.

The Fossil Record
Fossils provide evidence that organisms from the past are not the same as those found today, and demonstrate a progression of evolution. … The resulting fossil record tells the story of the past and shows the evolution of forms over millions of years.
