What is a fossil evidence of?
A fossil is evidence of a once living animal. A fossil is created when an animal dies in a mud or other soft dirt or sediment. Over time, the animal will decompose and leave the bones. Over time, these bones will get covered by dirt, rocks water, etc. After a couple thousand years the bones will get compressed into sediment, waiting to be discovered. Something similar to a fossil is and imprint. This is where an impression of a plant or animal is pushed into a soft sediment and hardens.
How does a cast fossil form?
When the animal dies its skeleton settles on the sea floor and is buried by sediment. that thickens and begins to turn to stone. The skeleton dissolves and a mold is formed. Minerals crystallize inside the mold and the cast is formed.
