Where do fossils come from?
A fossil is any evidence of past life. Fossils are as diverse as the living things that left them behind, and can range from microscopic plant pollen to giant dinosaurs.

Most organisms die and decay, leaving no remains behind, but in rare circumstances a dead organism can become fossilized. Fossils are primarily found in sedimentary rock, which is formed on the Earth’s surface. Layers of sedimentary rock are formed by accumulating particles like sand or silt. Sometimes, plants and animals become buried in this sediment, which protects them from scavengers, organic decay, or weathering. Once buried, water carrying dissolved minerals may flow through the remains, leading them to be preserved at the cellular level. Find more information about fossils.
