£ 36.00
GENUINE GRAPHOCERAS DECORUM AMMONITE FROM LOUSE HILL QUARRY, DORSETThis genuine Graphoceras decorum ammonite fossil comes from the Inferior Oolite
Formation at Louse Hill Quarry, Sherborne, Dorset, UK. Dating from the Middle Jurassic, Aalenian stage, this carefully chosen fossil is an excellent British ammonite specimen with strong geological, scientific, and display appeal. Fossils from named Dorset localities are highly desirable among collectors, especially when supplied with a clear species identification, formation, age, 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 piece for a fossil cabinet, collector’s tray, desk display, educational collection, or natural history gift. FOSSIL TYPE, SPECIES AND CLASSIFICATIONGraphoceras decorum 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.Graphoceras is a recognised Jurassic ammonite genus commonly associated with the family Graphoceratidae and the order Ammonitida. Ammonites of this group are important to palaeontology because their rapid evolution and widespread distribution make them useful for dating and correlating Jurassic marine rocks. A named species such as Graphoceras decorum gives this fossil stronger scientific and collecting interest than a general ammonite specimen. MORPHOLOGY AND NATURAL FEATURESGraphoceras ammonites typically have a planispiral shell, meaning the shell coils in a single flat plane. They are often relatively compressed in profile, with neat whorl development and refined ornamentation. Depending on preservation, specimens may show curved ribbing, fine growth lines, a defined outer margin, shell surface, mineral replacement, sediment staining, or natural matrix attachment.Like other ammonites, Graphoceras 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 spiral form, whorl profile, ribbing, and overall ornament are important features used in ammonite identification and make fossils like this appealing for both display and study.Natural colour variation, exposed matrix, worn areas, mineralised surfaces, and small irregularities are part of the fossil’s authentic preservation. These features reflect the specimen’s long geological journey from living marine animal to preserved Jurassic fossil. GEOLOGICAL AGE AND INFERIOR OOLITE FORMATIONThis specimen dates from the Aalenian stage of the Middle Jurassic and comes from the Inferior Oolite Formation. The Inferior Oolite is a famous British Jurassic rock unit known for fossil-rich limestones and oolitic sediments. Oolitic limestone is formed 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 Aalenian, the area now forming Sherborne and wider Dorset was covered by a shallow Jurassic sea. This environment supported ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, fish, and other marine life. After death, shells and hard parts could become buried in carbonate-rich sediment, eventually fossilising over millions of years. LOUSE HILL QUARRY, SHERBORNE LOCALITYLouse Hill Quarry at Sherborne is a notable Dorset locality for Middle Jurassic fossils. Specimens from named quarry localities are especially valued by collectors because they carry clear provenance and a stronger geological story. A Graphoceras decorum ammonite from this setting represents a direct connection to the ancient marine environments preserved within the Inferior Oolite Formation.The Dorset and Somerset Jurassic successions are well known for their ammonite faunas, and fossils from these rocks are widely collected for their scientific, educational, and decorative value. This specimen combines a named species, a recognised formation, a defined geological stage, and a classic British locality. GENUINE SPECIMEN WITH CERTIFICATE OF AUTHENTICITYThis Graphoceras decorum 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 Graphoceras decorum ammonite from the Inferior Oolite Formation is an excellent addition to a British Jurassic fossil collection. It pairs well with other ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and marine fossils from Dorset, Somerset, and the wider Jurassic Coast region.With its named species identification, Aalenian age, Middle Jurassic geology, Louse Hill Quarry locality, Sherborne provenance, Inferior Oolite Formation origin, and included Certificate of Authenticity, this fossil offers strong collecting, educational, and decorative appeal.
