Jellyfish
jelly fish don't have any bones
Jellyfish do not have muscles or bones in their uniquely designed bodies.
Dinosaur bones are made of hard, durable material like calcium phosphate, which is more resistant to decay than the soft tissue of jellyfish. Jellyfish are composed mainly of water and soft tissues that decompose quickly, making it harder for them to fossilize. The conditions needed for fossilization, such as rapid burial and protection from scavengers, are more likely to occur for hard, mineralized bones than soft-bodied organisms like jellyfish.
No bones, but they do have a hydrostatic skeleton.
