Cleoniceras Ammonite with Red Ammolitic Iridescence – Cretaceous, Madagascar This exceptional Cleoniceras ammonite from Madagascar displays remarkable areas of natural red ammolitic iridescence, producing vivid flashes of crimson and fiery orange when viewed under direct light. Dating from the Early Cretaceous period, approximately 110 million years ago, this specimen combines the scientific interest of a well-preserved ammonite with the striking visual appeal of its iridescent shell preservation. The polished surface reveals the natural chamber structure and shell morphology, while several areas preserve spectacular iridescent reflections caused by the preservation of the original aragonitic shell layers. Subtle dendritic mineral inclusions and variations in mineralization further enhance the specimen's aesthetic character. Specimens exhibiting this degree of natural red iridescence are particularly sought after by collectors, as they combine paleontological significance with gemstone-like optical effects. Locality: Madagascar Geological Age: Early Cretaceous, approximately 110 million years old Preservation: Polished ammonite with naturally preserved red ammolitic iridescence A highly decorative and scientifically fascinating fossil, ideal for collectors of exceptional ammonites, natural art objects, and rare iridescent fossils. A plastic display stand is included.
