rapid burial and hard parts
It is called a mold fossil, which can become a cast fossil. After the soft parts of the animal rot away, a cavity remains (the mold fossil) which becomes filled with hardened sand or mud (the cast fossil).
Being a fossil is not an adaptation. Fossilization is quick burial that prevents decay. An example of an adaptation is when an organism becomes attuned to a new habitat or environment by gaining or losing a past trait

It is a microscopic fossil, as of a pollen grain or unicellular organism.
a fossil in which minerals replaces all or part of an organism
A fossil is proof that an animal existed at one time, leaving evidence in rock. If that fossil does not appear in successive layers, there is no proof that the organism existed beyond its fossil record, and it is considered to have gone extinct.

foot prints and ammonites mainly, but any kind of organism if it had any contact with mud, under the right condition, it might just becomes a fossil

a helix fossil is a fossil that becomes an omanyte
No coral is NOT sediment. Coral SAND is a sediment but the coral itself is a living organism - if buried and lithified, the coral becomes a fossil.
A fossil is a trace of an organism that lived long ago.
