Douvilleiceras Ammonite Fossil Lower Albian Cretaceous Madagascar Genuine Authentic Specimen

Description Genuine Douvilleiceras Fossil Ammonite from Madagascar Presented here is a beautifully preserved Douvilleiceras fossil ammonite, originating from the Lower Albian stage of the Early Cretaceous Period, approximately 113–110 million years old. This specimen was discovered in Madagascar, a region world-famous for producing some of the most striking and scientifically valuable ammonites. Each fossil is carefully selected for its authenticity, preservation, and natural appeal, with the photographs provided showing the exact specimen you will receive. A Certificate of Authenticity is included, guaranteeing that this fossil is a genuine specimen and not a replica. Geological Context – Lower Albian, Early Cretaceous The Lower Albian represents a pivotal interval within the Early Cretaceous, a time marked by globally rising sea levels and the spread of shallow epicontinental seas. Madagascar, during this period, was positioned within the southern hemisphere of the supercontinent Gondwana and was home to diverse marine life. Fine-grained marine sediments in this region created an ideal depositional environment, preserving ammonite shells in remarkable condition. The Albian stage is especially significant for paleontology and stratigraphy due to the abundance of well-preserved ammonites, which serve as vital index fossils. Their rapid evolutionary rates allow scientists to use them for fine-scale correlation of Cretaceous rock layers across different continents, making this specimen not only a collector’s piece but also a scientifically meaningful fossil. Species Overview – Douvilleiceras The genus Douvilleiceras belongs to the Order Ammonitida, within the Superfamily Acanthoceratoidea and Family Douvilleiceratidae. Recognised for their distinctive morphology, these ammonites are instantly identifiable by: Strongly ribbed shells with bold, radial ribs running across the flanks. Prominent tubercles or nodes, giving the shell a robust and sculptured appearance. A generally planispiral form, with coiled whorls that display their ornamentation beautifully. Suture lines of moderate complexity, recording the intricate internal septa. These features reflect adaptations to a marine lifestyle in warm, shallow seas. Douvilleiceras was an active nektonic predator, feeding on smaller molluscs, crustaceans, and other marine organisms. Its sturdy ribbing and nodose ornamentation likely provided structural reinforcement for the shell while also serving hydrodynamic and possibly defensive functions. Paleontological Significance Specimens of Douvilleiceras are highly valued in both scientific research and fossil collecting communities. They are particularly important in defining biozones of the Lower Albian, with their distinctive shell features enabling geologists to pinpoint precise intervals of geologic time. Their global distribution – including Europe, Africa, and South America – makes them excellent reference fossils for correlating Cretaceous sequences worldwide. The Madagascan examples are especially prized due to their preservation and striking visual character. Many retain exquisite surface ornamentation that allows close study of their ribbing and tuberculation, offering insight into the evolutionary history and environmental adaptations of ammonites.
