Why are fossils important?
Fossil evidence is used to make inferences about life and environments at that time.
Construct a response on how fossilized animals get preserved if they do not turn to stone.
Fossilized animals get preserved by becoming trapped in amber, tar, peat or ice. They do not have to turn to stone in order to be preserved.
