That reminds me of another pseudo-shell that had me fooled. About ten years ago,
I started taking samples of beach drift in search of micro-shells. One object
that I found was a small, pink limpet about one centimeter in diameter with a
rough textured outer surface. I could find no reference to this creature in any
mollusc book, so I began to theorize as to what non-mollusc group it could
belong to. I came to the conclusion that it was the sieve plate from a large
starfish. A few years later, while looking through a generalized fossil book, my
mystery species leapt off the page. It was neither mollusk nor echinoderm, but a
bryozoan (sorry, my library is packed away for my impending relocation, and I
can't state the genus or order from memory). And while browsing further in that
same fossil book, I saw a fossil ostracod crustacean that looked exactly like
one of the "lepton clams" that I had sorted from the same samples. I guess it
pays to read as much as you can because you never know what you will find out. I
don't collect fossils, but I value the insights they give into modern forms. I
take it that your pistachio was plain-hulled, not the typical red-dyed variety.
That would have been a dead give away.
