Why a fish is more likely to become fossilized than a snake

It is very likely that any organism on Earth will be either eaten by scavengers or decomposed by microorganisms after it dies.

Explanation:

It is very likely that any organism on Earth will be either eaten by scavengers or decomposed by microorganisms after it dies. Organisms decompose more quickly when they are in contact with oxygen. or an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.
