How to Get Preserved as a Fossil (71) Unfortunately the
chances of any animal become a fossil are not very great, and (72) the
chances of a fossil then being discovered many thousand of years later are even
less. (73) It is not surprising that all the millions of animals that
have lived in the past (74) we actually have fossils of only very
few. (75) There are several ways into which, animals and
plants may become fossilized. (76) First, it is essential that the
remains are buried, as though dead animals and plants are quickly destroyed
(77) if they remain exposed the air. Plants rot, while insects and hyenas
eat the flesh and bones of animals. (78) Finally, the few remaining
bones soon disintegrate the hot sun and pouring rain. If buried in suitable
conditions, however, animal and plant remains will be preserved. (79)
The same chemicals change sand and silt into hard rock will aim enter the
animal and plant remains and make them hard too. (80) When this happens,
we say that they become fossilized.
