Fossils of hard mineral parts (like bones and teeth) were formed as follows: Some animals were quickly buried after their death by sinking in mud, being buried in a sand storm. Over time, more and more sediment covered the remains.

Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock."
