Possible Aturia Fragment?

[Cam G]

Hello! I'm new to this site and very happy to have found and joined this great community, while I generally focus my collecting on minerals im eagerly collecting fossils too. This is my personal favorite of the few I have collected, and it was found in a creek around Lewis County not far from Salmon Creek (Washington). I believe it may belong to a Aturia/nautilus replaced by chalcedony? Any feedback is greatly appreciated.

 

Thanks, Cam

Welcome to the Fossil Forum,  Cam...  I am in Florida but I have a couple of Aturia,  courtesy of my friend, @RJB who found and prepped many of them. He might be able to recognize yours...

More Oyster than Aturia

It kind of looks like a Crepidula fornicata

They can grow in cool spirals

It deffinetly looks more polecypod than nautiloid.  I know thats not much help but I dont know what it is.

I thought some kind of slipper shell too.  I've seen Pliocene ones from the California coast around Capitola.
