GENUINE GRAPHOCERAS STRIGOSUM AMMONITE FOSSILThis is a genuine Graphoceras strigosum ammonite fossil from the Inferior Oolite
Formation, Middle Jurassic, Bajocian Stage, collected from Burton Bradstock, Dorset, UK. This carefully chosen fossil specimen is an excellent piece for collectors of British ammonites, Jurassic fossils, Dorset fossils, extinct marine cephalopods, natural history specimens, and scientifically interesting display fossils.The photograph shows the actual fossil you will receive, allowing you to view the individual preservation, surface detail, colour, matrix, shell form, 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 CLASSIFICATIONGraphoceras strigosum 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 ornamentation, and rapid evolutionary changes make them highly valued by collectors and important in palaeontology.This specimen belongs to the genus Graphoceras and the species Graphoceras strigosum. Members of Graphoceras are associated with the family Graphoceratidae, a group of Middle Jurassic ammonites known for their compressed, elegant shell forms and importance in fossil-based dating of marine strata. Graphoceratid ammonites are especially useful in biostratigraphy because many species are linked to relatively precise intervals within the Jurassic.As a named ammonite species, Graphoceras strigosum has more scientific interest than a general ammonite specimen. It connects the fossil to a specific genus, species, age, locality, and geological formation, making it particularly appealing for collectors who prefer accurately labelled and well-contextualised fossils. GEOLOGICAL AGE, FORMATION AND LOCALITYThis fossil comes from the Inferior Oolite Formation of Burton Bradstock, Dorset, UK. The Inferior Oolite is a classic Middle Jurassic rock unit in southern England, famous for its fossiliferous limestones and rich marine fauna. It preserves evidence of warm, shallow seas that covered parts of Britain during the Bajocian Stage, approximately 170 to 168 million years ago.During the Bajocian, the Dorset region formed part of a shallow marine environment inhabited by ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, corals, and other marine organisms. Ammonites lived as active swimming cephalopods in these ancient seas. After death, their shells could sink to the sea floor, become buried in lime-rich sediment, and eventually fossilise through mineralisation, compaction, and geological alteration.Burton Bradstock is a well-known Dorset coastal locality within one of Britain’s most famous fossil-bearing regions. Fossils from this area are popular with collectors because they combine classic British Jurassic provenance with strong geological and palaeontological interest. AMMONITE MORPHOLOGY AND NATURAL FEATURESGraphoceras strigosum displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. The whorls represent successive stages of growth, expanding outward as the animal matured. Depending on preservation, the fossil may show whorl shape, compressed profile, ribbing, surface ornamentation, mineral staining, matrix attachment, and natural fossil texture.Ammonite shells were divided into internal chambers, with the living animal occupying the outer body chamber. These chambers assisted with buoyancy in the water column. The external shell shape, whorl proportions, ribbing, and other ornamentation are key features used by palaeontologists when studying and comparing ammonite species.Natural details such as weathered areas, small fractures, sedimentary contact marks, colour variations, mineral deposits, and matrix are part of the fossil’s geological history. These features add individuality and help distinguish a genuine natural fossil from artificial replicas or modern decorative casts. COLLECTING, DISPLAY AND EDUCATIONAL INTERESTThis Graphoceras strigosum ammonite fossil is ideal for display in a fossil cabinet, study, classroom, office, collection drawer, natural history arrangement, or British Jurassic fossil display. Its named species identification, Inferior Oolite Formation origin, Bajocian age, and Burton Bradstock locality give it strong collecting appeal.It is suitable for collectors of Dorset fossils, ammonites, Jurassic marine life, extinct cephalopods, British geology, and educational fossil specimens. The natural spiral form gives the fossil classic visual appeal, while the detailed locality and geological information make it a meaningful specimen for anyone interested in palaeontology and the ancient seas of Jurassic Britain. AUTHENTICITY AND SPECIMEN DETAILSThis is a genuine Graphoceras strigosum ammonite fossil from the Inferior Oolite Formation, Middle Jurassic, Bajocian Stage, Burton Bradstock, Dorset, UK. 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.
