    Pyrite Ammonites from Russia 
                                 WHAT ARE PYRITE AMMONITES?

    Ammonites replaced by Pyrite.
    From the Volga River Area, Saratov, Russia.
    About 150 Million Years Ago, during the Jurassic Period, these ammonites died in iron concentrated waters. The iron reacted to sulfur in the water and formed the iron pyrite which replaced the ammonite's more delicate structures, leaving the chambers and sutures exposed in glistening pyrite.
