Could this be a Fossil Jellyfish?

[Primigenia]

Hi all! this is my first post, and wanted to show you this 🌊 Rare Find - Could this be a Jellyfish? 🤔

Check out this incredibly rare find, It has some features that resemble a prehistoric jellyfish, but I'm not 100% sure. This find is truly unique and could represent a significant piece of our planet's marine history.

What do you think? Could this be a jellyfish fossil or something else? Drop your thoughts in the comments and let’s see what the fossil community thinks!

You will need to provide location information.

Ok sure

 

Found at Costa Azahar, Spain, according to maps is quaternary period.

Welcome to the forum.  Some general information is needed for IDs: location found (city or county and state) and size of the item.  Hands or other items aren't preferable since they can vary significantly.

Still quite a large area you are talking about.

I am not familiar with the area, or the time period, so I will let others answer as to what you may have found.

Personally, they look like sedimentary structures to me.

It looks like a sandstone (2) with clasts of limestone (1). The weathering in the clasts  with ridges looks like the dissolution of limestone. Are you able to see if the clasts (1) with ridges react (fizz) with an acid such as HCl? Try the acid in areas outside of the clasts (2). What happens?

very unlikely since jellyfish have no hard parts. its much more likely to be geological in nature

One way that clasts like this form is in turbidite. There can be fossils in the clasts, or some of the clasts can be fossils. Often, they are poorly preserved. I can imagine this being coral that isn't quite recognizable.

Jellyfish prints can be found in rare cases. In Solnhofen it is even relatively common for - usually very indistinct - imprints to be found. But they can also be found in Aix-en-Provence, France, and Painten, Germany.

 

The stripe-like pattern speaks against a jellyfish imprint in one direction, while the jellyfish impressions show more round structures.

upon reflection this was a bad comment since there are jellyfish fossils out there as other people have pointed out

 

specifically it is not how I would expect a jellyfish fossil to look, as Oilshale mentioned jellyfish fossils are often very indistict imprints due to the fossilization process while yours are very distinct 3d structures looking like actual jellyfish which is why i believe it is more likely to be a product of geological processes creating something that can be mistaken for something else

 

i should also clarify im by no means an expert so take everything i say with a grain of salt
