How is a fossil formed?
Explain as fully as you can
1.The animal sinks to the bottom of the sea
2. its flesh is eaten or weathered away, leaving only the bones
3. more rocks/sediment press down on the bones
4. the bones wearaway leaving behind the mould
5. the mould fills up with minerals, leaving behind a fossil
