GENUINE TARAMELLICERAS CF. BOULLESCOSTATUM AMMONITE FOSSILThis is a genuine Taramelliceras cf. boullescostatum ammonite fossil from the
Upper Jurassic, Middle Oxfordian, collected from Le Vanneau, Deux-Sèvres, Nouvelle-Aquitaine, France. 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, GENUS AND SCIENTIFIC IDENTIFICATIONTaramelliceras cf. boullescostatum 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.The identification Taramelliceras cf. boullescostatum means this fossil is comparable to Taramelliceras boullescostatum. The abbreviation “cf.” is used in scientific labelling when a fossil closely resembles a recognised species but is identified with careful caution, often because of preservation, natural wear, incomplete shell detail, or subtle variation. This gives the specimen strong scientific credibility while still linking it to a named ammonite form.Taramelliceras is commonly associated with the family Oppeliidae, a group of Jurassic ammonites often recognised for compressed, elegant shell shapes, refined coiling, and detailed surface ornamentation. Oppeliid ammonites are especially appealing to collectors who appreciate finely formed ammonites with strong scientific context and classic Upper Jurassic provenance. GEOLOGICAL AGE AND MIDDLE OXFORDIAN CONTEXTThis fossil dates from the Middle Oxfordian, within the Oxfordian Stage of the Upper Jurassic. The Oxfordian occurred approximately 164 to 157 million years ago and was a time of widespread marine environments across parts of Europe. Ammonites were abundant and diverse during this interval, making them valuable fossils for comparing and dating Jurassic sedimentary rocks.During the Middle Oxfordian, ammonites such as Taramelliceras 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. LE VANNEAU, DEUX-SÈVRES, FRANCE LOCALITYThis specimen comes from Le Vanneau in Deux-Sèvres, Nouvelle-Aquitaine, France. This region is known for Jurassic sedimentary rocks and fossil-bearing marine deposits that preserve evidence of ancient sea life from western France. French Jurassic ammonites are popular with collectors because they represent classic European marine faunas and provide well-contextualised specimens from significant geological intervals.During the Oxfordian, the area that is now western France was influenced by shallow marine conditions, with carbonate-rich sediments, limestones, marls, and sea-floor deposits preserving the remains of marine organisms. These environments supported ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other invertebrates. Over millions of years, some shells became preserved as fossils within the sedimentary rock record. AMMONITE MORPHOLOGY AND NATURAL FEATURESTaramelliceras cf. boullescostatum displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. The whorls represent successive growth stages as the ammonite matured. Species of Taramelliceras are often admired for their compressed profile, neat whorl shape, refined ornamentation, and balanced spiral form.Depending on preservation, this fossil may show whorl shape, fine ribbing, striated ornament, shell curvature, natural 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 characteristics give the specimen individuality and help distinguish a genuine natural fossil from a modern cast or replica. COLLECTING, DISPLAY AND EDUCATIONAL INTERESTThis Taramelliceras cf. boullescostatum 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 careful “cf.” identification, Middle Oxfordian 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 comparison, geological age, and Le Vanneau locality provide valuable scientific context for anyone interested in prehistoric marine environments. AUTHENTICITY AND SPECIMEN DETAILSThis is a genuine Taramelliceras cf. boullescostatum ammonite fossil from the Upper Jurassic, Middle Oxfordian, Le Vanneau, Deux-Sèvres, Nouvelle-Aquitaine, 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.
