Trionyx Turtle Carapace Fossil Eocene Isle of Wight Bembridge Authentic Specimen Certified Rare Shell
£ 60.00
Trionyx Turtle Carapace Fossil – Genuine Eocene Specimen from BembridgeThis authentic Trionyx turtle carapace (shell) fossil originates from the
Bembridge Oyster Bed within the Bembridge Marls Member of the Bouldnor Formation at Bembridge on the Isle of Wight. This locality is one of the most important Eocene fossil sites in the UK, known for its exceptionally preserved freshwater and lagoonal fauna. The specimen shown in the photographs is the exact fossil you will receive, carefully selected for its quality and detail. It is a genuine fossil and includes a Certificate of Authenticity with a lifetime guarantee.Discovery and Professional PreparationYour specimen was discovered by our experienced team members, Alister and Alison, ensuring full provenance from field discovery to final presentation. After careful excavation, the fossil was expertly cleaned, stabilised, and prepared by Alison. This meticulous preparation preserves the delicate structure of the shell while enhancing its natural features, making it suitable for both scientific appreciation and display.Geological Context – Bembridge Marls Member, Eocene EpochThe Bembridge Marls Member forms part of the Bouldnor Formation and dates to the late Eocene epoch, approximately 34 to 38 million years ago. The Bembridge Oyster Bed represents a calm, low-energy depositional environment consisting of freshwater to brackish lagoonal sediments. These conditions were ideal for preserving delicate vertebrate remains, including turtle shells. During this time, the Isle of Wight was a warm, subtropical region dominated by wetlands, rivers, and lagoons.About Trionyx – Softshell TurtleTrionyx belongs to the family Trionychidae within the order Testudines. These softshell turtles are characterised by their flattened, lightweight carapace and absence of rigid scutes seen in hard-shelled turtles. Instead, their shells were covered with a leathery skin, providing flexibility and improved hydrodynamics. This adaptation allowed Trionyx to thrive in aquatic environments, where they were efficient swimmers and ambush predators feeding on fish, invertebrates, and small vertebrates.Carapace Morphology and Notable FeaturesThis fossil carapace fragment displays the distinctive flattened structure typical of Trionyx turtles. Unlike hard-shelled species, the surface lacks pronounced scute divisions and instead shows subtle texturing that reflects the underlying bone structure. The fossil preserves the natural contours and form of the shell, offering insight into the evolutionary adaptations of softshell turtles. Mineralisation has enhanced the fossil’s appearance, with natural variations in colour and texture adding to its individuality.Palaeoenvironment and Ecological RoleDuring the Eocene, the Isle of Wight supported diverse freshwater ecosystems populated by turtles, crocodilians, fish, and early mammals. Trionyx turtles occupied an important ecological niche within these habitats, often inhabiting rivers and lagoons where they could hunt and forage. This fossil provides a direct connection to those ancient environments, offering valuable insight into the biodiversity and ecological dynamics of prehistoric Britain.Collector Appeal and Display ValueSoftshell turtle fossils from the Bembridge Marls are relatively uncommon and highly sought after by collectors. This specimen combines scientific significance with strong visual appeal, making it an excellent addition to any fossil collection. Its identifiable structure and high-quality preparation make it ideal for display in a cabinet, study, or educational setting.Authenticity, Provenance and PresentationThis fossil has been carefully chosen for its authenticity, condition, and aesthetic presentation. It is a genuine piece of natural history, professionally prepared and ready for display. Full sizing can be confirmed via the provided photographs, ensuring transparency before purchase. Each specimen is unique, preserving a fragment of an ancient turtle that once inhabited the Eocene wetlands of the Isle of Wight.
