Fossils
The rigidity of the hard body parts also allows the sediment to form around the organism. Soft body parts decay too fast for impressions to form and are not rigid enough for a mold to set around. The fossilization process. The fossilization process begins when the whole organism or hard body part is trapped in sediments.

Fossils Flashcards | Quizlet
Whether or not a dead organism becomes a fossil depends upon how well it's protected from scavengers and agents of physical destruction. however, quick burial isn't always enough to make a fossil. organisms have a better chance of becoming fossils. If they have hard parts such as bones, shells, or teeth. hard parts decay more slowly.

Organism
Organism Definition. An organism is a single individual, or being. While it may have many separate parts, the organism cannot survive without the parts, as the parts cannot survive without the organism. Some organisms are simple and only contain an information molecule describing how to obtain energy and reproduce the molecule.
Why do some things become fossils, but others do …
The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried. See more

Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species.

Why do the hard parts of organisms generally leave fossils?
When an organism dies, its soft parts often decay quickly or are eaten by animals. That is why only hard parts of an organism generally leave fossils. These hard parts include bones, shells, teeth, seeds, and woody stems. For a fossil to form, the remains or traces of an organism must be protected from decay.
