GENUINE NORMANNITES BRAIKENRIDGII AMMONITE FOSSILThis is a genuine Normannites braikenridgii ammonite fossil from the Middle
Jurassic, Bajocian Stage, collected from Gerzen, Germany. This carefully chosen fossil specimen is an excellent piece for collectors of German ammonites, Jurassic fossils, extinct marine cephalopods, natural history specimens, and scientifically 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, SPECIES AND SCIENTIFIC CLASSIFICATIONNormannites braikenridgii 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 ribbing, and rapid evolutionary changes make them highly valued by fossil collectors and important in palaeontology.This specimen belongs to the genus Normannites and the species Normannites braikenridgii. The genus is associated with the family Stephanoceratidae, a well-known group of Middle Jurassic ammonites commonly recognised for compact coiling, rounded whorls, strong ribbing, and a bold three-dimensional 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 Europe, with ammonites forming a diverse and abundant part of ancient marine ecosystems.During this interval, ammonites such as Normannites braikenridgii 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. GERZEN, GERMANY LOCALITYThis specimen comes from Gerzen, Germany, a European Jurassic fossil locality associated with marine sedimentary rocks from the Middle Jurassic. German Jurassic ammonites are highly collectable because they come from classic European fossil-bearing deposits and are often valued for their scientific interest, attractive shell forms, and well-studied geological context.During the Bajocian, parts of what is now Germany were covered by shallow seas connected to wider Jurassic marine environments across Europe. These waters supported ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other invertebrates. Sediments deposited on the sea floor later became fossil-bearing strata, preserving a record of ancient marine life from the Middle Jurassic. AMMONITE MORPHOLOGY AND NATURAL FEATURESNormannites braikenridgii displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. The whorls represent successive growth stages of the animal as the shell expanded during life. Ammonites in this group are often admired for their rounded whorls, visible umbilicus, strong ribbing, and sculptural appearance.Depending on preservation, this fossil may show rib detail, whorl shape, coiling pattern, 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, sedimentary contact marks, weathered surfaces, worn areas, mineral deposits, colour variation, and matrix are part of the fossil’s geological history. These features give the specimen individuality and help distinguish a genuine natural fossil from a modern cast or replica. COLLECTING, DISPLAY AND EDUCATIONAL INTERESTThis Normannites braikenridgii 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, German origin, and classic ammonite form give it strong collecting appeal.It is suitable for collectors interested in German 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 and locality information provide valuable scientific context for anyone interested in prehistoric marine environments.

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.
