£ 25.20
Witchellia cf. glauca Ammonite Fossil from Sherborne, DorsetThis is a genuine Witchellia cf. glauca ammonite fossil from the Inferior Oolite
Group, dating to the Middle Jurassic, collected from Sandford Lane Quarry, Sherborne, Dorset. This carefully chosen fossil is a desirable British Jurassic marine cephalopod specimen, selected for its natural character, geological interest, and collectable display appeal. It is supplied with a Certificate of Authenticity lifetime guarantee generic card, making it a trusted addition to an ammonite collection, fossil cabinet, natural history display, educational geology collection, or prehistoric gift selection.The photograph shows the actual fossil specimen you will receive. Full sizing and scale can be seen in the photo.Geological Age and FormationThis ammonite comes from the Inferior Oolite Group, one of the classic fossil-bearing Middle Jurassic rock units of southern England. The Inferior Oolite is well known for its limestones, sandy limestones, iron-rich horizons, shell beds, and diverse marine fossil assemblages. These rocks were deposited during the Middle Jurassic, when southern Britain was covered by warm shallow to moderately deep seas.The Inferior Oolite Group is particularly famous for its ammonite faunas, which are highly valued by collectors and geologists alike. Ammonites evolved rapidly and often had wide geographic distribution, making them important fossils for dating and correlating Jurassic rock layers. A fossil from this formation carries strong scientific and historic interest, especially when linked to a classic Dorset locality.Location: Sandford Lane Quarry, Sherborne, DorsetThis specimen was collected from Sandford Lane Quarry, Sherborne, Dorset, a locality associated with the rich Middle Jurassic geology of south-west England. Dorset is world famous for its Jurassic fossils, and its inland quarries, as well as coastal exposures, have produced many important ammonites and other marine fossils.During the Middle Jurassic, the Sherborne area lay beneath an ancient sea connected to broader European marine basins. Sediments accumulated on the seabed, including carbonate-rich mud, sand, shell fragments, and iron-rich material. These conditions helped preserve ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, crinoids, and other marine organisms within the Inferior Oolite succession.Fossil Type and IdentificationThis fossil is identified as Witchellia cf. glauca. The abbreviation “cf.” means the specimen compares closely with Witchellia glauca, while allowing for natural variation or preservation differences. This style of identification is commonly used for fossils that strongly resemble a known species but are best described with careful scientific caution.Witchellia is a Middle Jurassic ammonite genus associated with the diverse ammonite faunas of the Inferior Oolite. Ammonites were extinct marine molluscs related to modern squid, cuttlefish, octopus, and nautilus. They had hard, coiled external shells divided internally into chambers. The living animal occupied the outer body chamber, while earlier chambers helped regulate buoyancy, allowing the ammonite to move through the water column.Morphology and Notable FeaturesWitchellia ammonites are appreciated for their classic Jurassic coiled shell form and attractive natural ornament. Depending on preservation, specimens may show visible whorls, a defined umbilical area, ribbing, shell texture, mineralisation, and surface detail that records the growth of the animal’s shell. The coiled shell grew in stages, with each new whorl representing a later part of the ammonite’s life.The internal chambers of the shell were separated by walls known as septa. Where these septa met the outer shell, they formed suture lines, which are important in ammonite classification. The shell ornament, whorl shape, and overall proportions all contribute to the fossil’s scientific interest and visual appeal.As a genuine fossil, this specimen may show natural matrix, fossil shell detail, mineral staining, colour variation, weathering, small chips, cracks, or areas of natural wear caused by fossilisation and geological history. These features are normal for authentic fossils and add to the individuality of the piece. The photo shows the exact specimen being offered, allowing the buyer to view its condition, preservation, size, and display quality before purchase.Middle Jurassic Marine EnvironmentThis Witchellia cf. glauca ammonite lived in the warm Jurassic seas that covered Dorset during the Middle Jurassic. These marine environments supported a rich ecosystem of swimming cephalopods, seabed invertebrates, fish, and other marine organisms. Ammonites were active swimming or drifting animals, likely feeding on small prey in the water column using tentacles.After death, the ammonite shell could settle onto the seabed and become buried by sediment. Over millions of years, compaction, mineralisation, and geological change transformed the shell and surrounding sediment into fossil-bearing rock. This fossil is a direct link to the ancient Inferior Oolite seas of southern England, when dinosaurs lived on land and ammonites flourished in the oceans.Authenticity and CollectabilityThis Witchellia cf. glauca ammonite fossil is a genuine specimen from Sandford Lane Quarry, Sherborne, Dorset, dating to the Middle Jurassic within the Inferior Oolite Group. It is suitable for collectors of British fossils, Dorset fossils, Jurassic ammonites, Inferior Oolite fossils, marine cephalopods, natural history specimens, educational geology pieces, and display fossils.This carefully selected fossil includes a Certificate of Authenticity lifetime guarantee generic card, and the fossil shown in the photo is the actual specimen you will receive.
