Aioloceras Sp. - Early Cretaceous (145–100.5 million years ago) — Natural group of iridescent ammonites of the genus Cleoniceras Albiano – Early Cretaceous, Madagascar A graceful natural composition that houses numerous specimens of the genus Cleoniceras, extinct cephalopods that lived about 110 million years ago. The shells, beautifully preserved, show extraordinary mother-of-pearl iridescence, with hues ranging from pink to green, from gold to purple, depending on the incidence of light. Each ammonite is wrapped in a regular planispiral coil, with chambers visible in the rear polished section, where the complex sutures stand out, telling the evolutionary refinement of this group. The block is completely natural, sourced from a fossil-bearing formation in the southwest of Madagascar, one of the world's most renowned areas for the spectacular preservation of iridescent ammonites. The piece combines aesthetic value, chromatic rarity, and paleontological interest. Mounted in an autonomous position, it can be displayed in scientific collections, natural curiosity galleries, or as a fossil decorative sculpture. Details: Species: Cleoniceras sp. Period: Early Cretaceous (Albian, about 110 million years ago) Origin: Mahajanga Region, Madagascar Formation: Natural (unassembled) Features: Ammonites with iridescent mother-of-pearl and a visible polished section Preservation: Excellent, with authentic, unrestored structure and colors A fragment of a prehistoric ocean that unites nature's primordial beauty with the elegance of fossil forms.
