I am really new to this. I found this in South Dakota. That trip was my first attempt at finding fossils. I think I found this at the Mount Moriah Cemetery in Deadwood. A local expert said it was a Fossiliferous Concretion. I'm hoping for an idea of just what the fossils might be. These pics are front and back. PS the rock it is on isn't a fossil but Black Agate Thanks, Jeff
