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. Fossils can even provide clues to ancient climates. <sep>What are some things that Fossils can tell us?<sep>What animals were extinct
