£ 60.00
RARE STEPHANOCERAS LOKUTICERAS AMMONITE FROM OBORNE WOOD QUARRYThis rare Stephanoceras (Lokuticeras) ammonite fossil comes from the Inferior
Oolite Formation at Oborne Wood Quarry, Dorset, UK. Dating from the Middle Jurassic, Bajocian stage, Laeviuscula Subzone, this carefully chosen specimen is a highly interesting British ammonite with strong geological, scientific, and display appeal. Fossils from named quarry localities are especially desirable to collectors, and this piece benefits from a clear formation, stage, subzone, and locality.The photograph shows the actual fossil specimen you will receive, allowing you to view the real preservation, shell form, surface detail, matrix, colour, and natural character before purchase. Full sizing can be seen in the photo, making it easy to assess the scale and suitability of the fossil for a cabinet, collector’s tray, desk display, educational collection, or natural history gift. FOSSIL TYPE, GENUS AND SCIENTIFIC CLASSIFICATIONStephanoceras is an extinct ammonite genus 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 is extinct. Stephanoceras is generally placed within the order Ammonitida, superfamily Stephanoceratoidea, and family Stephanoceratidae.This specimen is listed as Stephanoceras (Lokuticeras), with Lokuticeras treated as a closely related subgeneric or specialist identification within the stephanoceratid ammonite group. Stephanoceratid ammonites are classic Middle Jurassic fossils, often recognised by their robust coiling, rounded whorls, strong ribbing, and ornamental tubercles or nodes. These features make them particularly attractive as display fossils and useful for understanding Jurassic ammonite diversity. MORPHOLOGY AND NATURAL FEATURESStephanoceras ammonites are known for their bold and sculptural shell form. They commonly show a planispiral coil with rounded to inflated whorls and strong ribbing running across the shell. Many specimens display branching ribs, raised nodes, or tuberculate ornament where ribs strengthen along the whorl flanks. This gives the ammonite a distinctive three-dimensional appearance compared with smoother or more compressed ammonite forms.Like other ammonites, Stephanoceras 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 ornament, whorl shape, rib density, and coiling pattern are all important features used in ammonite identification and make this fossil an appealing specimen for both collectors and educational displays.Natural features may include mineralised shell surface, exposed whorl detail, matrix attachment, sediment staining, worn high points, partial preservation, or small irregularities from fossilisation. These details are part of the specimen’s genuine geological character. GEOLOGICAL AGE, ZONE AND SUBZONEThis fossil comes from the Middle Jurassic, Bajocian stage, and is associated with the Laeviuscula Subzone. The Bajocian is an important interval in Jurassic palaeontology, with ammonites playing a key role in biostratigraphy. Ammonites evolved rapidly and were widely distributed in ancient seas, allowing palaeontologists to use them for dating and correlating rock layers.The Laeviuscula Subzone gives this specimen a more refined geological context than a general Middle Jurassic fossil. Subzone information is particularly valuable for collectors interested in stratigraphy, ammonite succession, and scientifically useful locality data. INFERIOR OOLITE FORMATION AND DORSET LOCALITYThe Inferior Oolite Formation is a famous British Jurassic rock unit known for fossil-rich limestones and oolitic sediments. Oolitic limestone forms from tiny rounded carbonate grains called ooids, which developed in warm, shallow marine waters where currents moved carbonate sediment across the sea floor.During the Bajocian, the area now forming Dorset was covered by a shallow Jurassic sea. This marine environment supported ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, fish, and other sea life. After death, shells and hard parts could become buried in carbonate-rich sediment, eventually fossilising over millions of years.Oborne Wood Quarry is a named Dorset locality, adding strong provenance and collector appeal. A Stephanoceras (Lokuticeras) ammonite from this setting represents a direct connection to the ancient Middle Jurassic seas preserved in the Inferior Oolite of southern England. GENUINE SPECIMEN WITH CERTIFICATE OF AUTHENTICITYThis Stephanoceras (Lokuticeras) 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, shape, and individual display character. COLLECTING, DISPLAY AND EDUCATIONAL APPEALA rare Stephanoceras (Lokuticeras) 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 and Somerset.With its rare stephanoceratid identification, Bajocian age, Laeviuscula Subzone, Oborne Wood Quarry provenance, Inferior Oolite Formation origin, and included Certificate of Authenticity, this fossil offers strong collecting, educational, and decorative appeal.
