This striking matched pair of sectioned ammonite fossils comes from Madagascar and belongs to the genus Cleoniceras, a marine cephalopod that lived during the Early Cretaceous Period, approximately 110–105 million years ago. Carefully cut and polished, the two halves reveal a beautifully mirrored interior, transforming a once-living ocean creature into a naturally formed work of art.

The exposed chambers display intricate spiraling sutures filled with crystalline mineralization, showcasing a rich palette of warm browns, honeyed ambers, creamy calcite, and smoky gray tones. Each chamber records a moment in the ammonite’s growth, offering a visible timeline of life in an ancient tropical sea.

Mounted individually on custom metal stands, the pair is designed to be displayed together or slightly apart, emphasizing their symmetry and sculptural presence. The clean, modern supports contrast elegantly with the organic complexity of the fossil, making this set equally suited for a refined interior, gallery display, or serious fossil collection.

Both scientifically evocative and visually dramatic, this Cleoniceras ammonite pair is a timeless reminder of Madagascar’s ancient marine past and a captivating centerpiece for collectors who appreciate fossils that bridge natural history and design.
