I found this fossil back in 2014 at Cedar Creek Reservoir in Franklin County, Alabama. I was told the fossils we'd find there would be Mississippian, contained in Bangor Limestone. When I first found this I thought it might be a trilobite butt or a shark tooth and I recently decided to try to clean it, and now I don't know what it is there are two depressions under each prong, and the prongs bow back up (couldn't really get a side pic)
The pictures show the uncovered fossil (the lighter material was what was initially uncovered).
Thank you for any assistance!
