Can you believe I found this just sitting there, sticking out of a block of landslide material on the beach and wiggled it out with a screw driver?  Never found even a suggestion of one before and this is only one of two I found in three days of carving through that block to discover the rest of its treasures. The other, sadly, is not in as good a shape, but still a treasure! Found at Matoaka Beach, St Leonard, Maryland.
