Hello! I recently went to Grand Ledge, Michigan. This area is part of the Carboniferous, and more specifically the Pennsylvanian period. I found this fossil that appears to be scales. It’s not an imprint either, the scales are elevated. In the surrounding rock there are cordiate fossils and some kind of clam, I found ferns in the area as well. I believe that it was a swamp land way back when these were all alive. An ID on what kind of plant or maybe even fish scales would be awesome! Thank you!
