Discover the beauty of ancient marine life with these stunning pyritized Quenstedticeras sp. ammonite fossils from Saratov, Russia. Dating back to the Jurassic Period, these remarkable specimens preserve the distinctive spiral shape and intricate ribbed shell patterns of ammonites that inhabited prehistoric seas millions of years ago.
Pyritization occurs when minerals such as pyrite (iron sulfide), often called "Fool's Gold," replace or fill portions of an organism during fossilization. This process can produce beautiful metallic fossils with exceptional detail.
These ammonites feature striking metallic tones of copper, bronze, and gold, with beautiful iridescent highlights that shimmer under different lighting conditions. Their deeply ribbed shells and natural spiral formations make each specimen a fascinating example of prehistoric marine life. The specimens appear to have undergone an acid treatment to enhance their metallic appearance and reveal their intricate surface details.
Measuring approximately 1.25–1.5 inches, these small but impressive fossils are wonderful additions to any fossil or natural history collection.
