Scaphopoda Tusk Shell Fossil Antalis striata Barton Formation Eocene Hampshire UK Genuine Fossil with Certificate of Authenticity

Description

Authentic Fossil Specimen

This listing is for a genuine fossil tusk shell from the species Antalis striata, belonging to the class Scaphopoda. Each specimen is carefully selected from the Barton Formation exposures at Barton-on-Sea, Hampshire, a world-renowned fossil site in southern England. These tusk shells date from the Eocene epoch, approximately 41–38 million years ago, and represent a fascinating glimpse into the rich marine ecosystems that once thrived in this region. Every fossil is guaranteed 100% authentic and comes with a Certificate of Authenticity for your peace of mind. The example shown in the photographs is representative of the quality you will receive, with specimens ranging in size from 25–40 mm. A 1 cm scale cube is included in the images for precise sizing reference.

Geological and Scientific Context

The Barton Formation is one of Britain’s most important fossil-bearing units, famous for its diverse molluscan assemblages and well-preserved marine fauna. It belongs to the Bartonian Stage of the Middle Eocene and has been extensively studied for both its stratigraphic and palaeontological significance. Within this formation, the Antalis striatatusk shell is a distinctive element, occurring in fine sandy clays that were deposited in a shallow marine shelf environment. These sediments record a warm, subtropical climate and provide evidence of a thriving benthic ecosystem where scaphopods, gastropods, bivalves, echinoids, and sharks coexisted.

Morphology and Features of

Antalis striata

Scaphopods, commonly called tusk shells, are slender tubular molluscs characterised by their tapering, slightly curved shells that are open at both ends. The species Antalis striata is distinguished by fine longitudinal striations running along its shell, giving it both its name and its distinctive appearance. These animals lived buried in soft marine sediments, extending their anterior end to feed on microscopic organisms such as foraminifera. Their unique morphology and burrowing lifestyle make them an important group for palaeoecological studies, shedding light on ancient benthic food webs and substrate conditions.

Palaeontological Importance

Fossils from the Barton Formation, including tusk shells, have long been collected by geologists and naturalists since the 19th century. They are frequently used in biostratigraphy, where their presence helps to define specific biozones within the Bartonian Stage. As part of the order Dentaliida and the superfamily Dentaliioidea, Antalis striatacontributes to our understanding of molluscan evolution and diversification during the Eocene. Their well-preserved shells offer both collectors and researchers tangible evidence of the evolutionary history of marine invertebrates.

A Collectors’ and Educational Piece

These tusk shell fossils are not only scientifically valuable but also visually striking specimens, ideal for display, teaching, or as part of a personal fossil collection. Their elegant, elongated forms make them excellent representatives of marine molluscan fossils, particularly from the Eocene of southern England. Whether you are a dedicated collector, a geology enthusiast, or seeking a unique natural history gift, these fossils provide a meaningful connection to Earth’s deep past.

Guarantee of Authenticity

All of our fossils are 100% genuine specimens, sourced responsibly and handled with care to preserve their natural integrity. Each specimen is accompanied by a Certificate of Authenticity, verifying its provenance from Barton-on-Sea, Hampshire, and confirming its geological age within the Eocene epoch. You can buy with confidence, knowing you are receiving an authentic piece of Earth’s history.
