A beautiful fossil ammonite attributed to Cleoniceras, featuring a well-preserved complete spiral structure with pronounced ribbing and a clearly visible umbilicus. Unlike sliced or polished specimens, this un-cut piece retains its complete original shell structure with fine detail in the rib pattern. The surface displays an attractive natural iridescence, with vibrant rainbow reflections—flashing green, gold, and copper hues typical of premium specimens from Madagascar. Mounted on a custom engraved wooden display stand detailing its classification, this piece is both a high-value collectible fossil and an elegant decorative showpiece. The fossil from the ArteTerra collection has been paired with a solid wood display base, custom-made to enhance its beauty and scientific value. On the front surface of the base, a laser-engraved naturalistic illustration depicts the prehistoric animal to which the specimen belongs, reconstructed in its original environment. In the bottom right corner, the "Arte Terra – Fossil Mineral Design" logo is featured as a guarantee of authenticity and artisanal craftsmanship of the product.
