A. How are fossils made?
The animal dies. The soft fleshy parts deteriorate. The bones and teeth that remain eventually are covered with sediment season after season. The bones and teeth are surrounded by silt and mud begins to turn into stone from the minerals in the sediment. The new rocks containing the bones and teeth are worked up to a dry surface so that they can dry out. Fossil hunters then discover these.
