GENUINE NORMANNITES CF. FORMOSUS AMMONITE FOSSILThis is a genuine Normannites cf. formosus ammonite fossil from the Inferior
Oolite Formation, Middle Jurassic, Bajocian Stage, Romani Subzone, collected from Milborne Wick, Dorset, UK. This carefully chosen fossil specimen is an excellent piece for collectors of British ammonites, Dorset fossils, Jurassic marine fossils, extinct cephalopods, natural history specimens, and scientifically labelled fossil display pieces.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 IDENTIFICATIONNormannites cf. formosus 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.The identification Normannites cf. formosus means the fossil is comparable to Normannites formosus. The abbreviation “cf.” is used in scientific naming when a specimen closely resembles a known species but is identified with a degree of caution, often due to preservation, natural wear, incomplete shell features, or subtle taxonomic variation. This careful wording gives the fossil strong scientific credibility while still linking it to a recognised ammonite form.Normannites is associated with the family Stephanoceratidae, a well-known Middle Jurassic ammonite family. Stephanoceratid ammonites are often recognised for their robust shell shape, rounded whorls, strong ribbing, and distinctive sculptural appearance. These ammonites are also important in Bajocian biostratigraphy, where their evolving forms help geologists compare and date marine rock layers. GEOLOGICAL AGE, FORMATION AND ROMANI SUBZONEThis fossil comes from the Inferior Oolite Formation, a classic British Middle Jurassic rock unit known for fossiliferous limestones, sandy limestones, iron-rich beds, and diverse marine fossil assemblages. The specimen dates to the Bajocian Stage of the Middle Jurassic, approximately 170 to 168 million years ago.It is associated with the Romani Subzone, a recognised ammonite-based biostratigraphic interval within the Bajocian. Ammonite zones and subzones are highly valuable in geology because ammonites evolved quickly and were widely distributed across ancient seas. This makes a labelled specimen such as Normannites cf. formosus especially appealing to collectors who appreciate fossils with precise geological context. MILBORNE WICK, DORSET LOCALITYThis fossil was collected from Milborne Wick, Dorset, UK, a locality connected with the fossil-rich Middle Jurassic deposits of southern England. Dorset is one of Britain’s most important fossil-producing counties, famous for its Jurassic rocks and long history of palaeontological study. While the coast is internationally known, inland Dorset localities also preserve important ammonite-bearing strata from the Inferior Oolite Formation.During the Bajocian, the Milborne Wick area lay beneath warm, shallow marine waters. These ancient seas supported ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, corals, and other marine organisms. Ammonites such as Normannites lived as active swimming cephalopods before their shells eventually settled onto the sea floor after death.Burial in carbonate-rich sediment helped protect some shells from destruction. Over millions of years, mineralisation, compaction, and natural geological alteration preserved the shell form as a fossil within the Inferior Oolite deposits. AMMONITE MORPHOLOGY AND NATURAL FEATURESNormannites cf. formosus displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. Stephanoceratid ammonites are often admired for their compact, rounded whorls and bold ribbing, giving them a strong three-dimensional appearance. Depending on preservation, this fossil may show rib detail, whorl shape, shell ornamentation, mineral staining, natural matrix, weathered surfaces, or fossilisation texture.The shell of an ammonite was divided internally into chambers, with the living animal occupying the outer body chamber. These chambers helped regulate buoyancy in the water column, while the outer shell shape, ribbing, whorl proportions, and ornamentation are key features used by palaeontologists when studying ammonite groups.Natural details such as small fractures, sedimentary contact marks, matrix attachment, worn areas, colour variation, and mineral deposits are part of the fossil’s geological history. These features add individuality and help distinguish a genuine fossil specimen from a modern cast or artificial replica. COLLECTING, DISPLAY AND EDUCATIONAL INTERESTThis Normannites cf. formosus ammonite fossil is ideal for display in a fossil cabinet, study, classroom, office, collection drawer, natural history arrangement, or British Jurassic fossil collection. Its genus-level identification, comparison to Normannites formosus, Inferior Oolite Formation origin, Bajocian age, Romani Subzone association, and Milborne Wick locality give it strong collecting value.It is suitable for collectors interested in Dorset fossils, British ammonites, Jurassic marine life, extinct cephalopods, palaeontology, geology, and educational fossil specimens. The natural coiled form gives the fossil classic visual appeal, while the detailed geological information adds scientific interest and makes it a meaningful specimen from the ancient seas of Jurassic Britain. AUTHENTICITY AND SPECIMEN DETAILSThis is a genuine Normannites cf. formosus ammonite fossil from the Inferior Oolite Formation, Middle Jurassic, Bajocian Stage, Romani Subzone, Milborne Wick, 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.
