Brasilia sp Ammonite Fossil Middle Jurassic Dorset UK Inferior Oolite Specimen with Certificate Horn Park Bajocian Collectable
£ 24.00
GENUINE BRASILIA SP. AMMONITE FOSSIL FROM DORSETThis is a genuine Brasilia sp. ammonite fossil from the Inferior Oolite
Formation, Middle Jurassic, Bajocian Stage, collected from Horn Park, Dorset, UK. This carefully chosen fossil specimen is an appealing piece for collectors of British ammonites, Jurassic fossils, marine cephalopods, natural history specimens, and classic Dorset palaeontology.The photograph shows the actual fossil you will receive, allowing you to view the individual preservation, colour, surface texture, matrix, shell form, and natural character of the specimen before purchase. Full sizing details can be seen in the photo. This fossil is supplied with a Certificate of Authenticity lifetime guarantee generic card, confirming it as a genuine specimen. FOSSIL TYPE, GENUS AND SCIENTIFIC INTERESTBrasilia sp. is an ammonite, an extinct marine cephalopod from 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 spiral shells, changing ornamentation, and wide distribution make them important fossils for collectors and for the study of ancient marine environments.This specimen is identified to genus level as Brasilia sp., meaning it belongs to the genus Brasilia while the exact species is not specified. Genus-level ammonite identifications are still highly useful and collectible, especially when supported by clear locality and geological formation information. Brasilia is associated with Middle Jurassic ammonite faunas and is of interest to collectors of British Bajocian fossils.Ammonites such as Brasilia are valued because their shells often preserve visible growth features, whorl development, ribbing, and other structural details. These features help palaeontologists compare ammonite groups and understand changes in Jurassic marine life through time. GEOLOGICAL AGE, FORMATION AND LOCALITYThis fossil comes from the Inferior Oolite Formation of Horn Park, Dorset, UK. The Inferior Oolite is a well-known Middle Jurassic rock unit in southern England, famous for its marine fossils and its importance in British geology. It includes limestones, sandy limestones, iron-rich beds, and fossiliferous horizons formed in ancient shallow sea environments.The specimen dates to the Bajocian Stage of the Middle Jurassic, approximately 170 to 168 million years ago. During this time, Dorset lay beneath warm, shallow marine waters. These seas supported a rich ecosystem of ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, corals, and other marine organisms.Horn Park is a notable Dorset fossil locality associated with the Inferior Oolite and its diverse Middle Jurassic fauna. Fossils from this area are popular with collectors because they represent a classic British Jurassic marine setting and often preserve scientifically interesting ammonite material. AMMONITE MORPHOLOGY AND PRESERVATIONBrasilia ammonites display the classic planispiral shell form, with the shell coiled in a flat spiral. The whorls represent successive stages of growth, expanding outward as the animal developed. Depending on preservation, the fossil may show ribbing, whorl shape, compressed shell form, surface ornament, natural mineral staining, matrix attachment, or fine fossil texture.Ammonites had chambered shells, with the living animal occupying the outer body chamber. The internal chambers helped regulate buoyancy, allowing ammonites to move through the Jurassic seas. The shell’s external shape and ornamentation are key features used when studying and identifying ammonites.Natural details such as small fractures, weathered areas, sedimentary contact marks, colour variation, mineralisation, and matrix are part of the fossil’s geological history. These features add character and help show that the specimen is a genuine natural fossil rather than a modern replica. COLLECTING AND DISPLAY APPEALThis Brasilia sp. ammonite fossil is well suited for display in a fossil cabinet, study, classroom, office, natural history collection, or British Jurassic fossil arrangement. Its combination of named genus, Inferior Oolite Formation origin, Middle Jurassic age, and Horn Park locality gives it strong collecting interest.It is suitable for collectors of Dorset fossils, ammonites, cephalopods, Jurassic marine life, British geology, and educational fossil specimens. The natural coiled form makes ammonites instantly recognisable, while the precise locality and formation details add scientific and display value.
