There have been many organisms that have lived in Earths past. Only a tiny number of them became fossils. Still, scientists learn a lot from fossils. Fossils are our best clues about the history of life on Earth. Fossils provide evidence about life on Earth. They tell us that life on Earth has changed over time. Fossils in younger rocks look like animals and plants that are living today. Fossils in older rocks are less like living organisms. Fossils can tell us about where the organism lived. Was it land or marine? Fossils can even tell us if the water was shallow or deep.
