GENUINE NORMANNITES LATANASATUS AMMONITE FROM OBORNE WOOD, DORSET

This genuine Normannites latanasatus ammonite fossil comes from the Inferior
Oolite Formation at Oborne Wood, Dorset, UK. Dating from the Middle Jurassic, Bajocian stage, Romani Subzone, this carefully chosen specimen is an excellent British ammonite with strong geological, scientific, and display appeal. Fossils with a named species, precise geological formation, stage, subzone, and locality are especially desirable for collectors who appreciate 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 the piece for a fossil cabinet, collector’s tray, desk display, educational collection, or natural history gift.

FOSSIL TYPE, SPECIES AND CLASSIFICATION

Normannites latanasatus is an extinct ammonite species belonging to the wider group of coiled marine cephalopod molluscs known as ammonites. Ammonites were related to modern squid, cuttlefish, octopus, and nautilus, although the ammonite lineage itself became extinct at the end of the Cretaceous Period.

Normannites is generally associated with the order Ammonitida, superfamily Stephanoceratoidea, and family Stephanoceratidae. This family includes many important Middle Jurassic ammonites known for robust coiling, rounded whorls, strong ribbing, and distinctive shell ornament. A named Normannites species from the Bajocian is a particularly appealing specimen for collectors interested in Jurassic cephalopods, British ammonites, and stratigraphically useful fossils.

MORPHOLOGY AND NATURAL FEATURES

Normannites ammonites typically show a planispiral coiled shell, meaning the shell coils in a single flat plane. They are often characterised by rounded whorls, strong ribbing, and sculptural ornament typical of many stephanoceratid ammonites. Depending on preservation, specimens may display primary ribs, branching rib patterns, raised nodes or tubercles, visible whorl structure, and natural mineralised shell surface.

Like other ammonites, Normannites had an internally chambered shell. The living animal occupied the outer body chamber, while the earlier chambers helped regulate buoyancy as the animal moved through the Jurassic sea. The shell’s ribbing, whorl profile, ornament, and coiling pattern are important features used in ammonite identification and make this fossil interesting for both study and display.

Natural features may include matrix attachment, sediment staining, worn high points, exposed whorl detail, partial shell preservation, mineral replacement, or small irregularities from fossilisation. These characteristics are part of the specimen’s authentic geological history and give it individual display character.

GEOLOGICAL AGE, ZONE AND SUBZONE

This fossil dates from the Bajocian stage of the Middle Jurassic and is associated with the Romani Subzone. The Bajocian was an important interval in ammonite evolution, with many distinctive ammonite groups developing in shallow marine environments. Because ammonites evolved rapidly and were widely distributed, they are highly useful for dating and correlating Jurassic rock layers.

The Romani Subzone gives this fossil a more precise stratigraphic context than a general Middle Jurassic ammonite. Subzone information adds value for collectors interested in fossil succession, biostratigraphy, and the detailed geological history of the Inferior Oolite Formation.

INFERIOR OOLITE FORMATION AND OBORNE WOOD LOCALITY

The Inferior Oolite Formation is a famous British Jurassic rock unit known for fossil-rich limestones and oolitic sediments. Oolitic limestone is made from tiny rounded carbonate grains called ooids, which formed in warm, shallow marine waters where currents moved carbonate sediment across the sea floor. These ancient sea-floor deposits later hardened into limestone, preserving shells and other remains from Jurassic marine life.

During the Bajocian, the area now forming Dorset was covered by a shallow Jurassic sea. This environment supported ammonites, belemnites, brachiopods, bivalves, gastropods, echinoids, fish, and other marine organisms. Oborne Wood is a named Dorset locality, giving this specimen strong provenance and a clear connection to the Middle Jurassic fossil record of southern England.

GENUINE SPECIMEN WITH CERTIFICATE OF AUTHENTICITY

This Normannites latanasatus 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 character.

COLLECTING, DISPLAY AND EDUCATIONAL APPEAL

A Normannites latanasatus ammonite from the Inferior Oolite Formation is an excellent addition to a British Jurassic fossil collection. It pairs well with other Middle Jurassic ammonites, belemnites, brachiopods, bivalves, gastropods, echinoids, and marine fossils from Dorset, Somerset, and the wider Jurassic Coast region.

With its named species identification, Bajocian age, Romani Subzone, Oborne Wood locality, Inferior Oolite Formation origin, and included Certificate of Authenticity, this fossil offers strong collecting, educational, and decorative appeal.
