GENUINE PSEUDOPPELIA OXYNOTA AMMONITE FOSSILThis is a genuine Pseudoppelia oxynota ammonite fossil from France, dating to
the Upper Jurassic, Lower Kimmeridgian. This carefully chosen fossil specimen is an attractive and scientifically interesting piece for collectors of French ammonites, Upper 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 CLASSIFICATIONPseudoppelia oxynota 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 development make them highly valued by collectors and important in palaeontology.This specimen belongs to the genus Pseudoppelia and the species Pseudoppelia oxynota. The genus name reflects its relationship to oppeliid-style ammonites, a group often recognised for compressed, elegant shell forms, refined coiling, and relatively delicate ornamentation compared with more heavily ribbed ammonite families. These features make Pseudoppelia oxynota an appealing fossil for collectors who appreciate finely shaped Upper Jurassic ammonites with strong scientific context. GEOLOGICAL AGE AND LOWER KIMMERIDGIAN CONTEXTThis fossil dates from the Lower Kimmeridgian, the early part of the Kimmeridgian Stage within the Upper Jurassic. The Kimmeridgian occurred approximately 157 to 152 million years ago and was a time of widespread marine environments across Europe. Ammonites were abundant and diverse during this interval, making them important fossils for comparing and dating Jurassic sedimentary rocks.During the Lower Kimmeridgian, ammonites such as Pseudoppelia oxynota lived as active swimming marine animals. Their shells were divided into internal chambers, with the living animal occupying the outer body chamber. This chambered shell helped regulate buoyancy in the water column, allowing ammonites to move through ancient Jurassic seas before their shells eventually settled onto the sea floor after death. FRENCH JURASSIC LOCALITY AND DEPOSITIONAL ENVIRONMENTFrance is well known for Jurassic fossil-bearing sedimentary rocks, including marine deposits that have produced many classic ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other marine fossils. French Upper Jurassic ammonites are popular with collectors because they represent well-studied European marine faunas and provide attractive, well-contextualised specimens from important geological intervals.The sediments that preserve Lower Kimmeridgian ammonites were deposited in marine environments, often involving limestones, marls, clays, mudstones, or carbonate-rich sea-floor deposits. These settings allowed ammonite shells to become buried after death and preserved through mineralisation, compaction, and natural geological alteration. Depending on preservation, fossils from these deposits may show shell detail, matrix, mineral staining, subtle ornamentation, or natural compression. AMMONITE MORPHOLOGY AND NATURAL FEATURESPseudoppelia oxynota displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. The whorls represent successive stages of growth as the ammonite matured. Ammonites of this general form are often admired for their balanced spiral outline, compressed whorl profile, narrow umbilical area, and refined surface features.The species name oxynota suggests a sharp or angular shell character, and specimens of this type may show an elegant compressed profile, neat whorl curvature, fine ribbing or striation, natural shell ornament, mineral staining, matrix attachment, surface wear, or fossilisation texture. The outer shell shape, whorl proportions, ornament pattern, and umbilical structure are important features used in ammonite comparison and identification.Natural details such as small fractures, sedimentary contact marks, worn areas, colour variation, mineral deposits, 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 Pseudoppelia oxynota ammonite fossil is well suited for display in a fossil cabinet, study, classroom, office, collection drawer, natural history arrangement, or Upper Jurassic fossil collection. Its named species identification, Lower Kimmeridgian 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 and geological age provide valuable scientific context for anyone interested in prehistoric marine environments.
