Perfect egg shape black shale/pyrite concretion. 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.
