The worm is made up of all soft tissue which makes it much harder to help preservation.
A worm would stand a poor chance of being fossilized because worms have no hard parts.
What is fossil?
An animal or plant from a previous geologic era that has been preserved in the Earth's crust as a fossil, remnant, impression, or trace. The main repository for knowledge regarding the evolution of life on Earth is the complex of information preserved in fossils found all across the world.
Only a small percentage of extinct species have been preserved as fossils, and often only those with a sturdy skeleton are capable of doing so. A calcareous skeleton or shell is present in the majority of major groups of invertebrate creatures (e.g., corals, mollusks, brachiopods, bryozoans).
Other types have silicon dioxide or calcium phosphate shells (both of which are found in the bones of vertebrates). A fast burial following deposition may leave these in a shell or bone.
Therefore, A worm would stand a poor chance of being fossilized because worms have no hard parts.
