Answer: worms have no hard parts
Explanation:
A fossil is a hard remain of the dead being which used to live on earth. It may belong to plant, animal or any other creature who used to have hard body parts such as teeth, bones, shells, wooden parts and others. As when the organism dies the soft body parts are decomposed off and only hard parts are left. These hard parts are preserved under the heap of earth in the sedimentary rocks as fossil.
The worms usually have soft body parts which can be easily decomposed off by the soil microbes after death. Hence, they cannot be preserved as fossils.
