Beautiful fossil ammonite attributed to Cleoniceras, featuring a well-preserved spiral structure with pronounced ribbing and a clearly visible umbilicus. The surface displays attractive natural iridescence, with subtle rainbow reflections typical of specimens from Madagascar. The shell shows fine detail in the rib pattern and natural preservation of the original structure, making it both a collectible fossil and an elegant decorative piece. 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.
