A hard shell organism have more of a chance to become a fossil .
At the bottom of a lake buried by a landslide
There are many factors that make it more likely that an animal will be preserved as a fossil. One factor is living in a swampy area.
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.
Among the possible environments that might hold fossils:There are fewer fossils from land creatures than marine creatures.There is no evidence of life living in lava or igneous rocks because we know for certain that a) Organisms cannot live in lava (plant matter burns, lack of oxygen deprives animals of life) b) fossil evidence is destroyed due to the melting and recrystallization of the lava.Most fossils are found in rocks from marine environments. Famously, graptolites are best preserved in black shale.You cannot say for certain that there were no land creatures, but because land fossils would be exposed to erosion and weathering. Most fossils are formed as a result of a tranquil marine environment allowing the dead organism to sink to the bottom of the water body, and are covered. In the absence of oxygen, the form is preserved and is fossilised.
A good index fossil is one of an organism that rapidly evolves and is widespread throughout a geologic time period or periods. This makes it useful in determining the age of the rock formation in which it is contained.

A preserved fossil is an organism or Animal that has been PERFECTLY PRESERVED for lots of years, or however old it may be. For example, a wooly mammoth frozen in the ice for millions of years would be known as a preserved fossil.There are 2 different types of fossil preservation- preservation with alteration and without. With alteration also has different types. The type of organism you are looking for depends on the how it was preserved.
In order to know which of these animal parts is most likely to be preserved as a fossil one needs to know the available choices for answers.
most likely the organism will die
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.
Of the three organisms it is the snails that has the least chance of becoming a fossil since it has no skeleton.
An organism that has a hard structure is most likely to become a fossil because it can survive through different weather changes and an organism with a soft structure will most likely dissolve or decompose.
Improve the organism's survivability in it's environment.
No. Preservation as a fossil is most likely when the organism is buried quickly. Slow burial gives opportunity for decay and other destructive processes to occur.
hard parts on the outside of the organism means that the potential fossil is more likely to survive as increasing pressures are placed on the potential fossil when sediments are placed on top.
