The body of a jellyfish can be excluded due to the absence of fossil records. Jellyfish have soft bodies that do not typically fossilize well, making it rare to find fossilized remains. In contrast, the shells of snails and crabs, as well as the bones of dinosaurs, have more likelihood of being preserved as fossils.
