How can something with no bones have a fossil? Jelly fossils are hard to come by because, to be formed, the animal must be buried quickly with sediment.
This jellyfish fossil is from the Cambrian period, more than 500 million years ago. It was found buried in Utah—an area that used to be underwater, covered by the ocean.
