Epimayaites falcoides Ammonite Fossil Jurassic Madagascar Genuine Authentic COA
£ 36.00
AUTHENTIC JURASSIC FOSSIL FROM MADAGASCARThis Epimayaites falcoides ammonite fossil is a genuine specimen from the Upper
Oxfordian stage of the Late Jurassic, collected near Beraketa in south-west Madagascar. Carefully chosen for its striking preservation, this ammonite represents both an important scientific specimen and a visually stunning fossil. The photographs show the actual piece you will receive, with a 1 cm scale cube provided for accurate sizing. Every specimen is accompanied by a Certificate of Authenticity, confirming that it is 100% genuine. GEOLOGICAL AGE AND PROVENANCEThis fossil dates back approximately 163–157 million years to the Upper Oxfordian stage of the Jurassic Period. During this time, Madagascar was part of the great southern supercontinent Gondwana, positioned within the influence of the Tethys Ocean. Shallow, warm seas dominated the region, depositing marine sediments that captured and preserved the remains of ammonites and other marine creatures. The Beraketa area of south-west Madagascar is world-famous for its Jurassic ammonites, which display superb preservation and often retain remarkable ornamental detail. SPECIES IDENTIFICATION AND CLASSIFICATIONEpimayaites falcoides belongs to the class Cephalopoda, order Ammonitida, superfamily Perisphinctoidea, and family Perisphinctidae. The genus Epimayaites is an Oxfordian ammonite group characterised by its large, strongly ribbed shells and well-developed planispiral form. The species falcoides is a distinctive member of this group, known for its elegant ornamentation and its significance in Jurassic stratigraphy. Its presence within Upper Oxfordian horizons makes it a valuable index fossil for geologists working on the Late Jurassic stratigraphic framework. MORPHOLOGY AND DISTINCTIVE TRAITSThis specimen displays the classic features of Epimayaites falcoides. The shell is planispiral and robust, with bold ribs running across the flanks that may bifurcate towards the outer whorl. These ribs form a striking ornamentation pattern, giving the ammonite both structural strength and aesthetic appeal. The compressed whorls and sharp ribbing reflect adaptations that allowed this cephalopod to thrive in the Jurassic seas, aiding buoyancy control and providing shell reinforcement against predators and water pressure. Its symmetry and preserved ornamentation make it a particularly desirable fossil for collectors. SCIENTIFIC AND STRATIGRAPHIC IMPORTANCEEpimayaites falcoides is an important ammonite in Upper Oxfordian biostratigraphy. Its distinctive morphology and occurrence in well-defined stratigraphic horizons make it a reliable index fossil for correlating Jurassic rock layers across Madagascar and other parts of Gondwana. This species also helps paleontologists reconstruct the evolutionary history of ammonites during the Late Jurassic, a time of significant diversification within the Perisphinctidae. For collectors, this fossil represents a piece of Earth’s history that has direct relevance to geological research and time-scale calibration. CONDITION AND PRESENTATIONThis fossil has been carefully prepared to reveal its ribbing, whorl structure, and natural form, while ensuring its durability for display. The shell features are clearly visible, showcasing the defining characteristics of the species. This is a one-of-a-kind specimen, not a replica or cast. The photographs provided show the exact ammonite you will receive, ensuring full transparency and confidence in its authenticity. GUARANTEE OF AUTHENTICITYAll of our fossils are 100% genuine, responsibly sourced, and scientifically identified. Each specimen is supplied with a Certificate of Authenticity to verify provenance. This Epimayaites falcoides ammonite fossil from Beraketa, Madagascar, is both scientifically significant and visually impressive, making it an outstanding addition for fossil collectors, natural history enthusiasts, and educational collections.
