They don't leave an impression in sandy deposits because their bodies are easily deformed. Only an extremely fine silt substrate is capable of preserving their fragile shape. It's the same reason vertebrate fossils are almost always bones or other hard tissues.
It is possible to find jellyfish fossils, but they are rare because jellyfish have soft bodies that are not easily preserved. In some cases, fossilized impressions of jellyfish have been discovered in certain types of sedimentary rocks that have preserved their soft tissue.
Jellyfish fossils have been found in sedimentary rock formations around the world, generally in areas where ancient seas once existed. The soft-bodied nature of jellyfish makes their preservation as fossils rare, but in some cases, the impressions left by their bodies in sediment have been preserved and fossilized over millions of years. Scientists use careful excavation techniques to uncover and study these fossils to learn more about the evolution and history of jellyfish.
Yes, fossilized bones are bones that have been replaced by minerals over time, turning them into rock-like structures. These fossilized bones can provide valuable information about past life on Earth.
Yes, growth rings have been found on fossilized fish scales. These rings, similar to tree rings, can provide information about the age and growth rate of the fish during its lifetime. Studying these growth rings can help researchers understand the fish's environment and lifecycle.
Amoebas are single-celled organism which had previously been thought not to have been fossilized. However, on December 22, 2011 a group of scientists reported that they had discovered single-celled fossils.
don't have bones dissolve
They do not have any bones. No bones means there is nothing to fossilize.

The English popular name jellyfish has been in use since 1796. They were called fish because they were found in the sea.

The naruma jellyfish. It has been discovered in November 2009.
You can not get rid of jellyfish, they have been in the ocean forever. They are here to stay.
No. Artifacts are strictly things that have been modified by human action.

It's been speculated that increasing fishing activity have caused jellyfish predator numbers to dwindle, thus allowing jellyfish numbers to increase. Large masses of jellyfish have been referred to in the ecological and oceanic communities as "jellyfish joyrides". All jellyfish have the ability to sting their prey, and in massive numbers they become far more hazardous to life. Humans have been victims of jellyfish attacks, sometimes resulting in death due to excessive levels of venom from jellyfish stingers.
