£ 12.60
GENUINE PSEUDOGRAPHOCERAS LITTERATUM AMMONITE FOSSILThis is a genuine Pseudographoceras litteratum ammonite fossil from the Inferior
Oolite Formation, Middle Jurassic, Lower Bajocian, Dorset, UK. This carefully chosen fossil specimen is an attractive and scientifically interesting piece for collectors of British ammonites, Jurassic fossils, Dorset fossils, extinct marine cephalopods, and natural history specimens.The photograph shows the actual fossil you will receive, allowing you to view the individual preservation, colour, surface texture, shell form, 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, SPECIES AND SCIENTIFIC CLASSIFICATIONPseudographoceras litteratum 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 from the Jurassic Period. Their coiled shells, rapidly changing forms, and wide distribution make them highly valued by fossil collectors and important to palaeontologists.This specimen belongs to the genus Pseudographoceras and the species Pseudographoceras litteratum. The genus is associated with Middle Jurassic ammonite faunas and is of particular interest because graphoceratid-style ammonites are useful in the study of Jurassic marine strata. Named ammonites such as this are desirable because they provide more detail than a general ammonite fossil, connecting the specimen to a specific fossil type, age, formation, and British locality. GEOLOGICAL AGE AND INFERIOR OOLITE FORMATIONThis fossil comes from the Inferior Oolite Formation, a classic British Middle Jurassic rock unit. The Inferior Oolite is well known for its fossiliferous limestones, sandy limestones, iron-rich beds, and diverse marine fossils. It represents a time when parts of southern Britain were covered by warm, shallow seas with rich marine ecosystems.The specimen dates to the Lower Bajocian, an early part of the Bajocian Stage of the Middle Jurassic, approximately 170 million years ago. During this interval, ammonites were abundant and diverse, making them excellent fossils for identifying and comparing rock layers. Their evolutionary changes through time allow geologists to use ammonites as important biostratigraphic markers in Jurassic sediments. DORSET JURASSIC LOCALITYDorset is one of the most famous fossil-producing regions in the UK and is internationally known for its Jurassic geology. Fossils from Dorset are highly collectible because they come from classic British marine deposits and represent ancient environments that supported ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, corals, and other marine organisms.During the Lower Bajocian, the Dorset region formed part of a shallow marine setting. Ammonites such as Pseudographoceras litteratum lived in these seas as active swimming cephalopods. After death, their shells could settle onto the sea floor, become buried in lime-rich sediment, and eventually fossilise through mineralisation, compaction, and long-term geological alteration. AMMONITE MORPHOLOGY AND NATURAL FEATURESPseudographoceras litteratum displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. The whorls represent successive growth stages of the animal, expanding outward as the ammonite matured. Depending on preservation, the fossil may show whorl shape, compressed profile, ribbing, shell ornamentation, natural mineral staining, matrix attachment, and surface texture.Ammonite shells were divided into internal chambers, with the living animal occupying the outer body chamber. The chambered shell structure helped with buoyancy in the water column. The outer shell form, whorl proportions, ribbing, and ornamentation are among the key features used when studying and comparing ammonite species.Natural details such as weathered areas, small fractures, sedimentary contact marks, colour variation, mineral deposits, and matrix are part of the fossil’s geological history. These features add individuality and help distinguish a genuine fossil specimen from an artificial cast or modern decorative replica. COLLECTING, DISPLAY AND EDUCATIONAL INTERESTThis Pseudographoceras litteratum ammonite fossil is well suited for display in a fossil cabinet, study, classroom, office, collection drawer, natural history display, or British Jurassic fossil collection. Its named species identification, Inferior Oolite Formation origin, Lower Bajocian age, and Dorset locality give it strong collecting appeal.It is ideal 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 geological information adds scientific value and makes it a meaningful specimen from the ancient seas of Jurassic Britain. AUTHENTICITY AND SPECIMEN DETAILSThis is a genuine Pseudographoceras litteratum ammonite fossil from the Inferior Oolite Formation, Middle Jurassic, Lower Bajocian, 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.
