the body of a jellyfish

Answer 1

The body of a jellyfish can be excluded due to the absence of fossil records. Jellyfish are primarily composed of soft tissues that do not fossilize well, which makes it difficult to find fossil evidence of their existence. In contrast, the shells of crabs and snails, as well as a dinosaur's backbone, are made of harder materials that are more likely to be preserved in the fossil record.
