Am I crazy? Fish or fluke??

My only true "questionable" find whether it is something or not.  I love learning about geology, that said after we purchased 3 acres on land which was under glacial units (Puget lobe in WA state, possibly Pleistocene) I dug a hole near what would have been a bank however many thousands of years ago (16,500 years ago would have been glacial outwash).

 

I crack rocks open to see mineral composition.  This was found slightly above (maybe 1'-2'), what I would label the alluvial line, but I am very much an amateur when it comes to defining specifics.  

 

Google fish fossils and there is nothing like it,  I personally see clear and distinct fin outlines.  BUT that is why I would LOVE to hear your feedback and any thoughts!

 

This "fish outline" is small, 3.5" x 1".  But if a fish i would think pretty rare find based on our locations climate/environment.  Thank you for your time!

An ironstone concretion, I think.

Yup. Looks to be purely geological. The fishy looking mineral staining is the result of the fascinating pareidolia phenomenon.

No actual fish morphology here - no skeleton, no scales, no bones. 

No fin rays or skull elements. 

 

I have to agree with the geologic origin for this.
