Glen's story about the okra pod that looked like a snail shell reminds me of one of my foolish moments. We had collected some 25 species of Eocene gastropod fossils from an Alabama roadcut site. I was sorting them at home and, as usual, had a group of shells I couldn't quickly identify. I went through these, looking through my books and kept coming back to what looked like a small slipper shell but no ID. Well, I made several attempts to ID the thing and then something clicked somewhere and I realized I was looking at half of very modern pistachio shell. Talk about feeling stupid!
