How are fossils formed!

Fossils are formed when layers of rock cover the bone of an animal or a plant.First soil covers the animal, than sand covers the animal, and finally gravel is the last layer that covers the plant or animal.

Example of how they are formed

A crustacean is killed i while swimming in the ocean. The crustaceans body slowly sinks to the bottom of the ocean. Over time its body decays. Only the shell is left. After millions of years the body is covered with different layers of soil.
