From a famous fossil deposit of 300-million-year-old Ammonites along the Volga River in Russia (Jurassic Callovian Stage-161 million years ago). After burial, the original ammonite shell material was partially converted by mineralizing fluids rich in iron and sulfur into pyrite. The sliced fossil now reveals an awesome view of living chambers of the ammonite coated with splendent brassy yellow pyrite
