Why would a worm stand a poor chance of being fossilized?

Question

Worms have no soft parts.

Worms did not exist in the geologic past.

Worms have been rare during the geologic past.

Worms have no hard parts.

Answer 1

Worms have no hard parts. Fossilization typically favors organisms with hard structures, such as bones or shells, because these materials are more durable and more likely to be preserved over geological time. In contrast, worms, which are primarily composed of soft tissue, have a lower likelihood of being fossilized because their bodies decay quickly after death, leaving little to no trace behind.
