Melchiorites falcistriatus iridescent fossil ammonite – albian, cretaceous – madagascar – mother of pearl shell – certified genuine specimen

Description Available here is a superb Melchiorites falcistriatus fossil ammonite, exhibiting remarkable iridescence and a beautiful preservation of its mother of pearl shell. This specimen dates from the Albian stage of the Early Cretaceous period, approximately 113 to 100 million years ago, and originates from Mitsinjo, Madagascar – a location globally renowned for its exceptional fossil ammonites. Melchiorites is a genus of extinct ammonites known for their finely detailed shell ornamentation and dynamic coiling. These marine cephalopods once roamed the ancient seas, moving via jet propulsion and using their tentacles to capture prey. Their shells, often composed of aragonite, could preserve their stunning nacreous layers under favourable fossilisation conditions, creating the vibrant rainbow-like shimmer seen on this specimen. The ammonite has been carefully polished to reveal the colourful play of light within the nacre, showcasing hues of pink, green, blue, and gold. The exceptional preservation of the original shell material makes this a particularly collectible and visually striking fossil.
