Bizarre duck head shaped black shale with pyrite portion at top. Bottom portion is black shale with high pyrite content. Nature's magic trick. Natural geologic feature of pyrite in black shale concretion. These concretions are found in sizes as large as 5 feet across, but few have the showy pyrite and small sizes like these are even rarer. We predict that this new find will be quickly exploited and become a rarity in the near future.
