The first step in the process of how fossil are formed is _________

• As time passes, sediment hardens into rock, layering on top of the animal or plant part. The bones or shells decay into minerals, joining the rock.

• An animal dies in a wet environment (such as a riverbank).

• The animal's body or plant's leaves are covered in mud. Soft tissues or organs decompose or are eaten by other living things.

• The hard parts are left behind. (bones, teeth, claws, beaks, etc.)
