Hi all,
I picked up a couple slabs of fossiliferous limestone at some eroding bluffs of Lake Michigan last week and cracked them open. I had a good brachiopod pop right out, and another that had weathering on the top of it, but it looks pretty decent. Looking for guidance on what these may be. My ancient Golden Book guide seems to point towards Atrypa perhaps?
