Jellyfish used to have skeleton frames during evolution

Researchers in China have discovered fossils of early jellyfish during evolution that lacked tentacles but possessed a skeleton that shaped the body.

Jellyfish used to have a skeleton

Compared to today's ctenophore , the skeleton structure has disappeared.

Six fossils collected in southern China show that ancient jellyfish developed in different directions.

The research report on this strange fossil jellyfish has just been published in Science Advances magazine.

UPI news agency quoted Qiang Ou scientist from Peking University (China) that he was surprised to realize that the fossil collected showed that the ctenophore jellyfish had a skeleton, perhaps before we have missed rare specimens like this to be able to detect them sooner.
