Description
Ichthyosaur Jaw Section with Tooth – Authentic Jurassic Marine Reptile Fossil
This exceptional Ichthyosaur jaw section with an intact tooth is a genuine fossil specimen recovered from the world-famous Black Ven Marls of Lyme Regis, part of the UNESCO-listed Jurassic Coast in Dorset, UK. Dating to the Lower Lias of the Early Jurassic period (approximately 201–174 million years ago), this piece represents a fascinating glimpse into prehistoric marine ecosystems.
Carefully selected for its quality and scientific interest, this fossil displays a preserved section of jawbone alongside a distinct tooth, offering both aesthetic appeal and educational value. The exact specimen shown in the photographs is the one you will receive, ensuring complete transparency and authenticity. This fossil also includes a fully hand-signed Premium Certificate of Authenticity.
Geological Context – Black Ven Marls, Lower Lias Formation
The Black Ven Marls are part of the Lower Jurassic Lias Group, a sequence of alternating clay-rich marls and limestone layers deposited in a shallow epicontinental sea. These sediments are particularly renowned for their exceptional fossil preservation, especially marine reptiles, ammonites, and other marine fauna.
The depositional environment was a relatively calm, low-energy seabed where fine sediments allowed delicate skeletal material to be buried rapidly, aiding fossilisation. Periodic anoxic conditions further contributed to the preservation of organic remains, making Lyme Regis one of the most significant fossil localities in the world.
Fossil Identification – Ichthyosaur (Order: Ichthyosauria)
Ichthyosaurs were highly adapted marine reptiles, resembling modern dolphins in body shape but belonging to a completely different lineage. This jaw fragment likely originates from a member of the Ichthyosauria order, which dominated marine environments during the Jurassic.
The preserved tooth is conical and robust, a classic feature of Ichthyosaurs, adapted for grasping slippery prey such as fish and cephalopods. The jawbone fragment shows natural bone texture and structure, with clear integration of the tooth within the matrix, highlighting its authenticity and minimal interference during preparation.
Morphology and Notable Features
- Partial jaw section with naturally embedded tooth
- Classic conical tooth morphology typical of Ichthyosaur feeding adaptations
- Original marine matrix from the Black Ven Marls
- Excellent natural preservation with visible structural detail
- Genuine fossil with no restoration or artificial enhancement
These features make the specimen highly desirable for both collectors and educational purposes, offering insight into the feeding behaviour and anatomy of early marine reptiles.
Historical and Collecting Significance
Lyme Regis is historically significant as the birthplace of early palaeontology, with pioneering fossil discoveries made by Mary Anning in the early 19th century. Ichthyosaur remains were among the first marine reptiles ever scientifically described, and specimens from this locality continue to be highly sought after worldwide.
Owning a fossil from Black Ven connects directly to this rich scientific heritage, making it not only a display piece but also a tangible part of palaeontological history.
Authenticity and Presentation
This fossil is a 100% genuine specimen, carefully sourced and prepared. It comes complete with a fully hand-signed Premium Certificate of Authenticity, guaranteeing its provenance and legitimacy. The fossil shown in the images is the exact piece you will receive.
