£ 36.00
GENUINE STEPHANOCERAS SUBZOGENZOITHENSE AMMONITE FOSSILThis is a genuine Stephanoceras subzogenzoithense ammonite fossil from the
Middle Jurassic, Bajocian Stage, collected from Évrecy, Calvados, Normandy, France. This carefully chosen fossil specimen is an excellent piece for collectors of French ammonites, Jurassic fossils, extinct marine cephalopods, natural history specimens, and well-labelled palaeontological display pieces.The photograph shows the actual fossil you will receive, allowing you to view the individual preservation, shell form, colour, surface detail, 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 CLASSIFICATIONStephanoceras subzogenzoithense 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, varied ribbing, and rapid evolutionary changes make them highly valued by fossil collectors and important in palaeontology.This specimen belongs to the genus Stephanoceras and the species Stephanoceras subzogenzoithense. Stephanoceras is associated with the family Stephanoceratidae, a well-known Middle Jurassic ammonite family often recognised for robust shell forms, rounded whorls, strong ribbing, and a bold sculptural appearance. Stephanoceratid ammonites are especially significant in Bajocian biostratigraphy because their shell forms help geologists compare and date marine sedimentary strata. 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 seas across much of western Europe, with diverse marine communities and abundant ammonite faunas. Ammonites were particularly important during this interval because they evolved rapidly and were widely distributed, making many genera and species useful for understanding the relative age of Jurassic rock layers.During the Bajocian, ammonites such as Stephanoceras 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. ÉVRECY, CALVADOS, NORMANDY LOCALITYThis specimen was collected from Évrecy in Calvados, Normandy, France. Normandy is well known for Jurassic sedimentary rocks and fossil-bearing marine deposits, particularly ammonites and other invertebrates from classic European Jurassic sequences. Fossils from this region are popular with collectors because they combine attractive preservation with strong geological and palaeontological interest.During the Middle Jurassic, the Normandy region formed part of a shallow marine environment connected to broader European seas. These waters supported ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other sea life. Sediments deposited on the sea floor later became fossil-bearing rocks, preserving evidence of these ancient marine ecosystems. AMMONITE MORPHOLOGY AND NATURAL FEATURESStephanoceras subzogenzoithense displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. Stephanoceratid ammonites are often admired for their strong three-dimensional form, rounded whorls, and pronounced ribbing. Depending on preservation, the specimen may show rib detail, whorl shape, coiling pattern, shell ornamentation, mineral staining, matrix attachment, surface wear, or fossilisation texture.The whorls represent the growth stages of the animal as the shell expanded during life. The external ornamentation, including ribbing and whorl proportions, is important in ammonite identification and comparison. Natural details such as small fractures, sedimentary contact marks, colour variation, worn areas, and mineral deposits are part of the fossil’s geological history and add individuality to the specimen. COLLECTING, DISPLAY AND EDUCATIONAL INTERESTThis Stephanoceras subzogenzoithense ammonite fossil is ideal 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, Normandy locality, 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, and educational fossil specimens. The natural coiled form gives the fossil immediate visual impact, while the scientific naming and locality information provide valuable context for anyone interested in prehistoric marine life and the ancient seas of Jurassic Europe. AUTHENTICITY AND SPECIMEN DETAILSThis is a genuine Stephanoceras subzogenzoithense ammonite fossil from the Middle Jurassic, Bajocian Stage, Évrecy, 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.
