Glochiceras subclausum Ammonite Fossil Jurassic France COA Genuine Oxfordian Fontenay Vienne Collector Display Specimen
£ 1.80
GENUINE GLOCHICERAS SUBCLAUSUM AMMONITE FOSSILThis listing is for a genuine Glochiceras subclausum ammonite fossil from the
Upper Jurassic, Oxfordian Stage, collected from Fontenay-sur-Dive, Vienne, Nouvelle-Aquitaine, France. This carefully chosen fossil specimen is an excellent example of a classic European Jurassic ammonite, ideal for collectors of French fossils, Oxfordian ammonites, fossil cephalopods, prehistoric marine life, natural history specimens, and educational geology displays.The photograph shows the actual fossil specimen you will receive, so the colour, preservation, shape, surface texture, and individual fossil character shown in the image belong to this exact piece. For full sizing, proportions, and scale, please see the photo. FOSSIL TYPE AND SPECIES INFORMATIONThis fossil is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, octopus, and nautilus. Ammonites are among the most recognisable and collectable fossils from the Jurassic Period, valued for their elegant coiled shells, chambered internal structure, varied ornamentation, and importance in dating ancient marine rock layers.The species is Glochiceras subclausum, an Upper Jurassic ammonite associated with Oxfordian marine deposits. Glochiceras is a Jurassic ammonite genus often known for refined shell form, compressed whorls, smooth to lightly ornamented flanks, subtle growth features, and graceful planispiral coiling. These ammonites are especially appealing to collectors who appreciate delicate shell morphology and fine natural detail rather than heavily ribbed or strongly spined forms.As with other ammonites, the shell was divided internally into chambers by septa. The living animal occupied the final outer body chamber, while the earlier chambers helped regulate buoyancy in the water column. This allowed ammonites to move through ancient seas as successful marine animals, leaving behind fossil shells that now provide a direct link to Jurassic ocean life. UPPER JURASSIC OXFORDIAN AGEThis ammonite dates from the Upper Jurassic Period, specifically the Oxfordian Stage, approximately 163 to 157 million years old. The Oxfordian was an important interval in Jurassic marine history, when ammonites were diverse, widespread, and evolving rapidly across warm seas.During the Oxfordian, large areas of western Europe were covered by shallow to moderately deep marine environments. These seas supported a rich ecosystem of ammonites, belemnites, bivalves, brachiopods, gastropods, crinoids, sponges, corals, fish, and marine reptiles. Ammonites such as Glochiceras subclausum lived in these waters as part of a complex marine food web.After death, the ammonite shell could sink to the sea floor and become buried beneath fine sediment. Over millions of years, mineralisation, compaction, and geological pressure preserved the shell as a fossil, creating a natural record of marine life from the Jurassic Period. FONTENAY-SUR-DIVE, VIENNE, FRANCE LOCALITYThis specimen comes from Fontenay-sur-Dive, Vienne, Nouvelle-Aquitaine, France, a region with notable Jurassic fossil-bearing deposits. French Jurassic ammonites are highly regarded by collectors because they combine classic European locality data, attractive natural preservation, and strong geological interest.The Vienne and Nouvelle-Aquitaine region forms part of western France’s rich sedimentary record, preserving evidence of ancient marine environments that existed during the Jurassic. Fossils from this area help illustrate the ammonite faunas that inhabited the seas of what is now France. A fossil with clear species, geological stage, age, and locality information is far more desirable than an unlabelled decorative ammonite, as it can be properly catalogued and displayed within a scientific or educational collection. NATURAL COLLECTOR DISPLAY SPECIMENThis Glochiceras subclausum ammonite fossil is suitable for fossil collectors, geology students, teachers, natural history enthusiasts, and anyone interested in prehistoric marine life. It would display well in a fossil cabinet, educational teaching set, study collection, curiosity cabinet, or natural history-themed display.As a genuine natural fossil, the specimen may show typical characteristics such as matrix, mineral staining, surface texture, small cracks, weathering, repaired areas, or variations in preservation. These natural features are normal in authentic fossils and form part of the specimen’s geological history and collector appeal. CERTIFICATE OF AUTHENTICITY INCLUDEDThis fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. This provides reassurance that the fossil supplied is authentic and suitable for collecting, study, gifting, display, resale, or educational use.You will receive the exact Glochiceras subclausum ammonite fossil shown in the photo, from the Upper Jurassic Oxfordian of Fontenay-sur-Dive, Vienne, Nouvelle-Aquitaine, France.
