I went out day before yesterday for a little bit trying to get some hunting in before the big snow hits. I stumbled across a big chunck of sandstone,or so I thought. I tooki it home to the shop and stated to work on it and to my surprise it is shale from the Bear Paw! I was deceived by the 1/4" of sand stone on the outer layer. I hit it once with the chisel and out popped a nice Ammonite. By the time it was said and done I ended up with 4 nice Ammonites and a lot of bi valves. IThere are a lot of small(1") Ammonites still in the matrix and I am afraid I will damage them trying to remove them. A lot of the bi valves still had the pearly white on the outside. I also found 2 unopened bivalves, first for me. I The Ammonites all appear to be different, so any help would be great.
