People have always been interested in the Earth's early history. The people who study this type of history are called paleontologists. Fossils, whether they be plant or animal remains, give an indication what the environment was like a long time ago. Fossils also can indicate what the earth can expect in the future.

Fossils are traces of once living things that are preserved in rock. Because of how they are deposited in the sediment they can help date the layers of rock.
