£ 12.00
Genuine Sharpeiceras laticlavium Ammonite FossilThis listing is for a genuine Sharpeiceras laticlavium ammonite fossil from
Maitirano, Madagascar. It dates to the Upper Cretaceous, Cenomanian stage, specifically the Mantelli Zone, making it a desirable fossil with strong geological and palaeontological interest. This carefully chosen fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card.The photograph shows the actual fossil specimen you will receive, so the piece pictured is the exact fossil supplied. Full sizing details can be seen in the photo. This specimen is ideal for collectors of Cretaceous ammonites, Madagascar fossils, prehistoric marine life, natural history specimens, educational collections, and display-quality fossil pieces.Species and Fossil TypeSharpeiceras laticlavium is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, octopus, and nautilus. Ammonites possessed coiled, chambered shells, with the living animal occupying the outer body chamber while the internal chambers helped regulate buoyancy. Their shells often preserve important details such as ribs, tubercles, whorl shape, keel development, and suture patterns, all of which are used by palaeontologists to study ammonite classification and evolution.Sharpeiceras is a well-known Cretaceous ammonite genus associated with the acanthoceratid ammonites, a group often recognised for robust ornamentation and distinctive shell sculpture. Specimens of Sharpeiceras can show strong ribs, raised nodes or tubercles, and a bold whorl profile, giving them a striking appearance compared with smoother ammonite groups. These features make the genus especially appealing to collectors who appreciate dramatic shell form and well-defined Cretaceous ammonite morphology.Upper Cretaceous Cenomanian AgeThis fossil dates to the Cenomanian stage of the Upper Cretaceous Period. The Cenomanian was a time of warm global climates, high sea levels, and widespread shallow marine environments. Across many parts of the world, including regions around Madagascar, marine sediments preserved abundant ammonites and other sea life from this dynamic period of Earth history.The Mantelli Zone is an important ammonite biozone used in Cenomanian stratigraphy. Ammonite zones are valuable because ammonites evolved rapidly and were widely distributed through ancient seas, allowing geologists to compare and date marine rock layers with precision. A fossil from the Mantelli Zone therefore carries more than decorative appeal; it also represents a specific slice of Cretaceous geological time.Maitirano, Madagascar LocalityMaitirano in Madagascar is known for fossil-bearing Cretaceous deposits that preserve ammonites and other marine fossils from ancient seas around the island. Madagascar has long been an important region for ammonite collectors because many specimens display attractive preservation, strong ornamentation, and excellent geological provenance.During the Cretaceous, Madagascar was positioned within a changing southern hemisphere marine setting as the ancient supercontinent Gondwana continued to break apart. Marine basins around Madagascar supported diverse faunas, including ammonites, bivalves, gastropods, echinoids, fish, and other marine organisms. Fossils from these deposits provide a direct link to the tropical and subtropical seas that once surrounded the region.Morphology and Collectable FeaturesSharpeiceras laticlavium ammonites are especially collectable for their bold shell ornamentation. Depending on preservation, specimens may show prominent ribbing, raised tubercles, a defined whorl structure, a visible umbilicus, and natural mineralisation. These features reflect the original shell growth of the ammonite and give the fossil a strong sculptural quality.As a genuine natural fossil, this specimen may show normal signs of age and preservation, including surface texture, mineral replacement, matrix attachment, small chips, weathering, repairs, compression, or natural colour variation. These are typical characteristics of authentic fossils and form part of the individual geological character of the piece. This is not a modern replica, cast, or decorative imitation.Provenance and AuthenticityFossil type: AmmoniteSpecies: Sharpeiceras laticlaviumAge: Upper Cretaceous, CenomanianBiozone: Mantelli ZoneLocality: Maitirano, MadagascarCertificate: Includes a Certificate of Authenticity lifetime guarantee generic cardSpecimen shown: The photo shows the actual fossil you will receiveSize: Full sizing shown in the photoThis Sharpeiceras laticlavium ammonite fossil is a carefully selected natural history specimen with strong appeal for fossil collectors, geology enthusiasts, educational displays, and collectors of genuine Cretaceous marine fossils.
