Dead on!

Interesting sedimentary area, high degree of iron in some of it, red shale. The (not the correct term) clams came out a lower layer. A few were sent to some museums and we never did find out what exactly they were, other then big, 5-6 inches, both sides very intact. Not as much fun looking for fossils here as it was in West Virginia. You need a better trained eye then I do when going through the road cuts here, fish scales would escape me. I'm on the edge of hard coal country.
