A gorgeous Quenstedticeras lamberti ammonite from the Saratov region of Russia. Incredible pyrite replaced ammonite with a crystal lined interior. This ammonite has natural irredescent crystal colors - very nice. Excellent pyrite crystals! Middle Jurassic age. Authenticity guaranteed. Note - supply of these pyrite ammonites stopped in 2011. This is the last of my inventory.
