Here's a piece from my Windom Shale (Middle Devonian) that I'd really like to identify. Anyone recognize it? I can think of two possibilities, and I'm not sure where to look to be sure. 1) Fish coprolite 2) Worm #1 seems more likely, somehow... I think this was preserved inside one of the tubular pyrite nodules that are common in this shale. Whatever it is, it's interesting! It's about 1 mm long.
I've been experimenting with breaking down some Windom Shale from Penn-Dixie, and I think I have some ostracods: I have a few other interesting bits, too. Are these echinoid spines, micro-belemnite bits, or something else? And then there's this object: That's a small sampling. I also have found lots of brachiopod pieces, which is not surprising. The shale is rich in macrofossils, especially brachiopods, trilobites, horn corals, and occasional straight cephalopods.
