Description

Available for purchase is a magnificent Cleoniceras grycía besaivei fossil ammonite, featuring brilliant mother of pearl iridescence, from the Lower Albian stage of the Early Cretaceous period (approximately 113 to 100 million years ago). This stunning specimen comes from Mitsinjo, Madagascar, a region celebrated for some of the most beautiful and highly detailed ammonite fossils in the world.

Cleoniceras is an extinct genus of cephalopod molluscs, whose tightly coiled and beautifully ribbed shells provide a vivid record of ancient marine life. The grycía besaivei variety is particularly notable for its shell quality and the spectacular rainbow hues revealed upon careful polishing, showcasing vibrant flashes of green, blue, violet, pink, and gold.

Ammonites like Cleoniceras once thrived in the shallow seas that covered much of the Earth during the Cretaceous. Their fossilised shells, especially those with preserved aragonite layers, reveal a remarkable shimmering nacre (mother of pearl) effect, making them highly prized by collectors and natural history enthusiasts.
