How are they formed?
Fossils are created in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over a long period of time sediment builds over the top and hardens into rock. Thus creating fossils!!!
The process of being fossilized!
First and animal dies n a lake or ocean. Then the skin or the outer layer of the animal is decomposed so it leaves bones and shells. Finally sediment apply enough pressure that the bones leave an imprint on the rock.
