GENUINE NORMANNITES ORBIGNYI AMMONITE FOSSILThis is a genuine Normannites orbignyi ammonite fossil from the Middle Jurassic,
Bajocian Stage, collected from Caen, Calvados, Normandy, France. This carefully chosen fossil specimen is an attractive and scientifically interesting piece for collectors of French ammonites, Jurassic fossils, extinct marine cephalopods, natural history specimens, and well-labelled palaeontological display fossils.The photograph shows the actual fossil you will receive, allowing you to view the individual preservation, shell form, surface detail, colour, matrix, and natural character of this specific specimen before purchase. Full sizing details can be seen in the photo. This fossil includes a Certificate of Authenticity lifetime guarantee generic card, confirming it as a genuine specimen. FOSSIL TYPE, SPECIES AND SCIENTIFIC CLASSIFICATIONNormannites orbignyi is an ammonite, an extinct marine cephalopod belonging to the order Ammonitida. Ammonites were related to modern squid, cuttlefish, octopus, and nautilus, and are among the most recognisable fossils of the Jurassic Period. Their coiled shells, chambered internal structure, varied ornamentation, and rapid evolutionary changes make them highly valued by collectors and important in palaeontology.This specimen belongs to the genus Normannites and the species Normannites orbignyi. The genus is associated with the family Stephanoceratidae, a notable Middle Jurassic ammonite family often recognised for compact coiling, rounded whorls, strong ribbing, visible umbilicus, and a bold sculptural shell form. Stephanoceratid ammonites are especially important in Bajocian biostratigraphy because their evolving shell features help geologists compare and date marine sedimentary rock layers. GEOLOGICAL AGE AND BAJOCIAN CONTEXTThis fossil dates from the Bajocian Stage of the Middle Jurassic, approximately 170 to 168 million years ago. The Bajocian was a time of widespread shallow marine environments across much of western Europe, with ammonites forming an abundant and diverse part of ancient marine ecosystems.During this interval, ammonites such as Normannites orbignyi lived as active swimming marine animals. Their chambered shells helped regulate buoyancy in the water column, while the living animal occupied the outer body chamber. After death, the shell could settle onto the sea floor, become buried by sediment, and eventually fossilise through mineralisation, compaction, and natural geological alteration. CAEN, CALVADOS, NORMANDY LOCALITYThis specimen comes from Caen in Calvados, Normandy, France, a region well known for Jurassic sedimentary rocks and fossil-bearing marine deposits. Normandy has long been valued by fossil collectors for its classic European ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other marine fossils.During the Middle Jurassic, the Normandy region formed part of a shallow marine setting connected to wider European seas. Warm, carbonate-rich waters and sea-floor sediments helped create conditions in which ammonite shells could become buried and preserved. Over millions of years, these deposits became fossiliferous rock layers, recording the marine life that once inhabited the area. AMMONITE MORPHOLOGY AND NATURAL FEATURESNormannites orbignyi displays the classic planispiral ammonite form, with the shell coiled in a flat spiral. The whorls represent successive growth stages as the shell expanded during life. Ammonites of the stephanoceratid group are often admired for their rounded whorls, compact shape, pronounced ribbing, and strong three-dimensional appearance.Depending on preservation, this fossil may show rib detail, whorl shape, coiling pattern, visible umbilicus, shell ornamentation, natural mineral staining, matrix attachment, surface wear, or fossilisation texture. The outer shell shape, ribbing, whorl proportions, and umbilical structure are important features used in ammonite comparison and identification.Natural details such as small fractures, worn areas, sedimentary contact marks, weathered surfaces, colour variation, mineral deposits, and matrix are part of the fossil’s geological history. These characteristics add individuality to the specimen and help distinguish a genuine natural fossil from a modern replica or cast. COLLECTING, DISPLAY AND EDUCATIONAL INTERESTThis Normannites orbignyi ammonite fossil is well suited for display in a fossil cabinet, study, classroom, office, collection drawer, natural history arrangement, or Jurassic fossil collection. Its named species identification, Middle Jurassic Bajocian age, French origin, and classic ammonite form give it strong collecting appeal.It is suitable for collectors interested in French fossils, Jurassic ammonites, extinct cephalopods, marine invertebrates, palaeontology, geology, educational fossil specimens, and natural history display pieces. The natural coiled shell form gives the fossil immediate visual impact, while the species name, geological age, and Caen locality provide valuable scientific context for anyone interested in prehistoric marine environments. AUTHENTICITY AND SPECIMEN DETAILSThis is a genuine Normannites orbignyi ammonite fossil from the Middle Jurassic, Bajocian Stage, Caen, Calvados, Normandy, France. It includes a Certificate of Authenticity lifetime guarantee generic card. The photo shows the actual fossil you will receive, and full sizing information can be seen in the photo.
