Organisms are most likely to be fossilized when they are buried in sedimentary environments with low oxygen levels, such as deep underwater or in sediment layers on the ocean floor. The lack of oxygen slows down decomposition processes that would destroy the organic material, allowing for fossilization to occur.
Not all organisms are preserved as fossils because the conditions required for fossilization are rare. Factors such as rapid burial, absence of oxygen, and the presence of minerals must align to preserve an organism as a fossil. Additionally, the soft tissues of organisms often decay before they can be fossilized.

Those that have hard parts that fossilize, are plentiful, ubiquitous and evolve rapidly.
The condition that is necessary for an organism to become a fossil is rapid burial. The process itself is known as taphonomy. This rapid burial process keeps the organism from decaying naturally.

Most life-forms were single-celled, with no hard parts to fossilize.

Bones typically fossilize the most. There are some examples of fossilized feathers and hair, but it's rare.

Clam shells are quite durable.
The liquid from the remains of marine organisms is known as oil. When marine organisms die, their remains settle on the ocean floor and gradually undergo a process that turns them into oil under high pressure and temperature. Oil is a fossil fuel that is extracted from the Earth's crust and refined for various purposes, such as fuel and lubrication.
Not all organisms are equally protected from destruction after death, have structures which fossilize readily, or live and die in environments conducive to fossilization. Even if fossilization does occur, the fossil is subject to destructive geologic forces such as melting, crushing or erosion. And finally, most fossils remain hidden from us, buried deep inside the Earth.
Organisms are buried under sediment.

A mammoth is more likely to fossilize than a caterpillar because a caterpillar has no hard tissue. Bones and cartilage are much more likely to fossilize.
Most invertebrates do not fossilize because of the lack of bones or exoskeleton. Soft tissue rarely fossilizes. B for PLATO users
