Fossil
The preserved remains or traces of a living thing from long ago.
Most fossils form when a plant or animal is buried quickly in mud or sand, and over a long time the buried parts are replaced by minerals. Fossils can also be footprints or burrows.
Example: A fossil fish in a layer of rock shows that water once covered that place.
