Successful Freeze Thaw- Now What Is It?

[Rockpit]

I have been freezing and thawing this concretion since the end of July and it opened this morning.  Initially it seemed to look like some type of insect with wings folded on top of it.  I thought the bulbous parts on one end might be a head.  However, after I turning it another direction I   began wondering if it was a jellyfish.  The fossil extends beyond the mineral deposits.

I don’t see a fossil but perhaps someone more experienced in this area (I.E. @Nimravis ) might.

I would agree with jellyfish (Essexella asherae).  Let's see what Ralph (@nimravis) et al. say

I agree with Essexella with poor preservation.

I also agree with all- Essexella asherae.

Thanks everyone!
