Ok, here's a fossil I found off of Lake Michigan. There were numerous tiny shells and tiny fossils, then I found this. I looked under mollusk but it doesn't seem to fit, nor does clam or oyster, not the way it was formed but I could be wrong. It was barely showing in the stone and over the years I have been VERY carefully cleaning away at it and have gotten it down to the pictures shown.
