Ichthyosaur Partial Tooth Fossil Jurassic Coast Black Ven Charmouth Dorset UK

Description

Specimen Overview

Offered here is a genuine Ichthyosaur partial tooth fossil, recovered from the famous Black Ven Marls at Charmouth, near Lyme Regis, Dorset. This carefully selected specimen preserves part of an original ichthyosaur tooth and represents a direct piece of a Jurassic marine predator. Partial teeth from marine reptiles are far less commonly encountered than vertebrae or bone fragments, making this an especially appealing and informative fossil. The photographs show the exact specimen you will receive, with full sizing details clearly visible. As with all of our fossils, this specimen is 100% genuine and comes complete with a Certificate of Authenticity.

Geological Formation & Provenance

The fossil originates from Black Ven, one of the most important and productive fossil localities along the Jurassic Coast, a UNESCO World Heritage Site of global geological significance. The Black Ven Marls form part of the Lower Lias Group, deposited during the Early Jurassic Period, approximately 199–196 million years ago. These fine-grained marine mudstones were laid down in a relatively calm offshore environment, allowing organic remains to be rapidly buried and preserved. The same deposits that yield world-famous ammonites also preserve marine reptile material, including ichthyosaurs.

Fossil Type & Taxonomic Context

Ichthyosaurs were extinct marine reptiles belonging to the Order Ichthyosauria, highly adapted for fast, efficient swimming in open seas. With streamlined bodies, powerful tails, and strong jaws armed with conical teeth, they were dominant predators of Jurassic oceans. Ichthyosaur teeth were used to grasp slippery prey such as fish and cephalopods. Tooth material is particularly informative, as it reflects feeding behaviour and dietary adaptation, making specimens like this valuable from both a scientific and collecting perspective.

Morphology & Preservation

This specimen preserves a partial ichthyosaur tooth, showing the dense, robust structure typical of marine reptile dentition. The remaining portion retains natural surface texture and mineralisation, allowing appreciation of its original form despite partial preservation. Teeth are composed of extremely hard material, which contributes to their survival in the fossil record, though complete examples are still relatively uncommon. The fossil remains in a stable condition and retains its geological authenticity from the Black Ven Marls.

Depositional Environment & Formation

During the Early Jurassic, the region now forming Dorset lay beneath a warm, shallow sea rich in marine life. Ichthyosaurs thrived in these waters, preying on abundant fish and ammonites. After death or tooth loss during feeding, isolated teeth could settle onto the seabed and become buried within fine muds. Over millions of years, sediment compaction and mineral replacement preserved these remains within the marl, alongside invertebrate fossils that define the Lower Lias.

Scientific & Collecting Significance

Ichthyosaur fossils from Charmouth and Lyme Regis are internationally recognised and historically important, with the area closely associated with early discoveries that helped establish marine reptiles in palaeontology. Tooth material provides insight into feeding strategies and ecological roles within Jurassic marine ecosystems. Specimens from Black Ven are particularly prized for their reliable provenance and stratigraphic integrity, making them desirable to collectors, educators, and enthusiasts of marine reptiles.

Display, Care & Authenticity

This fossil is ideal for display in a private collection, educational setting, or natural history cabinet, offering a tangible connection to Jurassic marine predators. The specimen has been carefully cleaned to reveal natural features, with no artificial restoration or reconstruction. You will receive the exact fossil shown, accompanied by a Certificate of Authenticity, confirming its geological origin and genuine nature.

A rare and meaningful piece of Jurassic marine reptile history, this Ichthyosaur partial tooth from the Black Ven Marls represents an authentic fossil from one of Britain’s most iconic fossil localities on the Jurassic Coast.
