My earlike shell…

I found this eroded shell on a stony beach in Greece fifteen ears ago. I'd dearly love to find the matching one for my collection.

The one I have has a fine helix and scaphoid fossa, but the tragus is sadly no longer visible. I believe it to be a left ear.

I picked the shell up and put it in the pocket of my shorts and went swimming.

 Possibly an ancient herring aid.
