RARE NORMANNITES CF. FORMOSUM AMMONITE FROM OBORNE WOOD, DORSETThis rare Normannites cf. formosum ammonite fossil comes from the Inferior
Oolite Formation at Oborne Wood, Dorset, UK. Dating from the Middle Jurassic, Bajocian stage, Humphriesianum Zone, this carefully chosen fossil is a highly interesting British ammonite with strong geological, scientific, and display appeal. Fossils with a named genus, comparative species identification, precise formation, zone, geological age, and locality are especially desirable for collectors who value well-documented palaeontological specimens.The photograph shows the actual fossil specimen you will receive, allowing you to view the real preservation, shell form, surface detail, colour, matrix, and natural character before purchase. Full sizing can be seen in the photo, making it easy to assess the scale and suitability of this individual piece for a fossil cabinet, collector’s tray, desk display, educational collection, or natural history gift. FOSSIL TYPE, SPECIES AND SCIENTIFIC CLASSIFICATIONNormannites cf. formosum is an ammonite identification from the wider group of extinct coiled marine cephalopod molluscs known as ammonites. The “cf.” in the name means the specimen compares closely with Normannites formosum, while allowing for natural variation or preservation limits in exact species-level certainty. This wording is commonly used in palaeontology when a fossil strongly resembles a known species but is best presented with careful scientific caution.Normannites belongs to the order Ammonitida and is generally associated with the superfamily Stephanoceratoidea and family Stephanoceratidae. This family includes many classic Middle Jurassic ammonites known for robust coiling, rounded whorls, strong ribbing, and distinctive ornamental shell features. Normannites specimens are appealing to collectors because they combine bold fossil form with useful stratigraphic value. MORPHOLOGY AND NATURAL FEATURESNormannites ammonites typically display a planispiral shell, meaning the shell coils in a single flat plane. The whorls are often rounded to inflated, giving the fossil a strong three-dimensional appearance. Many stephanoceratid ammonites show pronounced primary ribs, branching secondary ribs, and raised nodes or tubercles depending on preservation, growth stage, and shell position.Like other ammonites, Normannites had an internally chambered shell. The living animal occupied the outer body chamber, while earlier chambers helped with buoyancy control in the Jurassic sea. The shell’s rib spacing, whorl profile, coiling pattern, and ornamentation are all important features used in ammonite study and identification.Natural features may include visible whorl structure, mineralised shell surface, matrix attachment, sediment staining, worn high points, partial shell preservation, or small irregularities from fossilisation. These details are part of the specimen’s genuine geological character and make each fossil unique. GEOLOGICAL AGE, ZONE AND FORMATIONThis specimen dates from the Bajocian stage of the Middle Jurassic and is associated with the Humphriesianum Zone. The Bajocian is a particularly important interval for ammonite evolution, with many distinctive ammonite groups developing in shallow marine environments. Ammonites are highly useful for biostratigraphy because they evolved rapidly and were widely distributed across ancient seas.The Humphriesianum Zone is named after Stephanoceras humphriesianum and is a recognised ammonite zone within the Bajocian. This zone information gives the fossil a more precise geological context than a general Middle Jurassic label, making it especially appealing for collectors interested in stratigraphy, fossil succession, and scientifically meaningful provenance. INFERIOR OOLITE FORMATION AND OBORNE WOOD LOCALITYThe Inferior Oolite Formation is one of the most famous British Jurassic rock units, known for fossil-rich limestones and oolitic sediments. Oolitic limestone forms from tiny rounded carbonate grains called ooids, which developed in warm, shallow marine water as currents moved carbonate particles across the sea floor. Over millions of years, these sediments hardened into limestone, preserving the remains of marine life.During the Bajocian, the area now forming Dorset was covered by a shallow Jurassic sea rich in ammonites, belemnites, brachiopods, bivalves, gastropods, echinoids, fish, and other marine organisms. Oborne Wood is a named Dorset locality, adding strong provenance and a clear connection to the Middle Jurassic fossil record of southern England. GENUINE SPECIMEN WITH CERTIFICATE OF AUTHENTICITYThis Normannites cf. formosum ammonite fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. The certificate provides added confidence for fossil collectors, schools, gift buyers, and anyone building a verified natural history collection.The fossil shown in the photograph is the actual specimen supplied. This means the piece you see is the piece you will receive, complete with its own natural preservation, shell detail, matrix, colour, form, and individual display character. COLLECTING, DISPLAY AND EDUCATIONAL APPEALA rare Normannites cf. formosum ammonite from the Inferior Oolite Formation is an excellent addition to a British Jurassic fossil collection. It pairs well with other Middle Jurassic ammonites, stephanoceratids, belemnites, brachiopods, bivalves, gastropods, echinoids, and marine fossils from Dorset and Somerset.With its rare comparative identification, Bajocian age, Humphriesianum Zone, Oborne Wood locality, Inferior Oolite Formation origin, and included Certificate of Authenticity, this fossil offers strong collecting, educational, and decorative appeal.
