GENUINE NORMANNITES CF. FORMOSUS AMMONITE FOSSILThis is a genuine Normannites cf. formosus ammonite fossil from the Middle
Jurassic, Bajocian Stage, collected from 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 fossil display pieces.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, GENUS AND SCIENTIFIC IDENTIFICATIONNormannites cf. formosus 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 structure, varied ribbing, and rapid evolutionary changes make them highly valued by fossil collectors and important in palaeontology.The identification Normannites cf. formosus means this fossil is comparable to Normannites formosus. The abbreviation “cf.” is used in scientific naming when a specimen closely resembles a known species but is identified with careful caution, often because of preservation, natural wear, incomplete shell detail, or subtle variation. This gives the fossil strong collecting interest while keeping the identification appropriately precise.Normannites is associated with the family Stephanoceratidae, a well-known Middle Jurassic ammonite family. Stephanoceratid ammonites are often recognised for robust shell forms, rounded whorls, pronounced ribbing, and a bold three-dimensional appearance. These ammonites are especially important in Bajocian biostratigraphy, where their evolving shell features help geologists compare and date marine sedimentary rocks. 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 the ancient sea fauna.During this interval, ammonites such as Normannites 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. CALVADOS, NORMANDY, FRANCE LOCALITYThis specimen comes from Calvados in Normandy, France, a region known for important Jurassic sedimentary rocks and fossil-bearing marine deposits. Normandy has long been valued by fossil collectors for its classic European Jurassic ammonites, belemnites, bivalves, brachiopods, echinoids, gastropods, and other marine fossils.During the Middle Jurassic, the Normandy region was part of a shallow marine setting connected to wider European seas. Warm, carbonate-rich waters and sea-floor sediments helped create the conditions in which ammonite shells could be buried and preserved. Over millions of years, these deposits became fossiliferous rock layers, recording the marine life that once lived in the area. AMMONITE MORPHOLOGY AND NATURAL FEATURESNormannites cf. formosus displays the classic planispiral ammonite form, with the shell coiled in a flat spiral. Stephanoceratid ammonites are often admired for their compact coiling, rounded whorls, strong ribs, and sculptural fossil appearance. The whorls represent successive growth stages of the animal as the shell expanded during life.Depending on preservation, this fossil may show a visible umbilicus, rib detail, whorl shape, shell ornamentation, natural mineral staining, matrix attachment, surface wear, or fossilisation texture. The outer shell shape, ribbing, and whorl proportions are important features used in ammonite comparison and identification.Natural details such as small fractures, weathered surfaces, sedimentary contact marks, colour variation, mineral deposits, and matrix are part of the fossil’s geological history. These features add individuality to the specimen and help distinguish a genuine natural fossil from a modern cast or replica. COLLECTING, DISPLAY AND EDUCATIONAL INTERESTThis Normannites cf. formosus ammonite fossil is well suited for display in a fossil cabinet, study, classroom, office, collection drawer, natural history arrangement, or Jurassic fossil collection. Its careful “cf.” identification, Middle Jurassic Bajocian age, French origin, and classic ammonite shape give it strong collecting appeal.It is suitable for collectors interested in French fossils, Jurassic ammonites, extinct cephalopods, marine invertebrates, palaeontology, geology, and educational fossil specimens. The natural coiled form gives the fossil immediate visual impact, while the geological age and locality information add scientific interest for anyone who appreciates well-contextualised fossils from prehistoric marine environments. AUTHENTICITY AND SPECIMEN DETAILSThis is a genuine Normannites cf. formosus ammonite fossil from the Middle Jurassic, Bajocian Stage, 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.
