Description
Authentic Ichthyosaur Articulated Vertebrae Fossil
This listing features an exceptional Ichthyosaur articulated vertebrae fossil from the famous Black Ven Marls, Lower Lias, Jurassic Coast: Stonebarrow Cliff, Charmouth, Lyme Regis, Dorset, UK. A remarkable specimen from the Early Jurassic Period (approximately 190–200 million years old), this fossil captures the preserved remains of one of the most iconic marine reptiles to have swum the Jurassic seas.
The specimen was discovered on 15 September 2025 by our team members, Alister and Alison, and meticulously cleaned, prepped, and treated by Alison to ensure preservation and display quality. The piece you see photographed is the exact fossil you will receive, and its size can be referenced against the 1 cm scale cube included in the images. Every fossil sold comes with a Certificate of Authenticity, guaranteeing it as a genuine specimen.
Geological and Palaeontological Context
The Black Ven Marls are part of the Lower Lias Group, one of the most fossiliferous Jurassic deposits in Europe, forming the backbone of the world-renowned Jurassic Coast UNESCO World Heritage Site. These marls and clays were deposited in a shallow epicontinental sea environment where fine sediments settled, burying and preserving marine life in extraordinary detail.
This setting created ideal conditions for preserving ichthyosaurs, ammonites, and other Jurassic marine fauna. The articulated nature of this vertebrae cluster suggests rapid burial in low-energy depositional environments, where skeletal elements remained undisturbed and intact.
About Ichthyosaurs
Ichthyosaurs were large marine reptiles belonging to the order Ichthyosauria. Although they resembled modern dolphins in overall body shape, they were not mammals but reptiles adapted to a fully aquatic lifestyle. Evolving during the Triassic, they thrived through much of the Jurassic and Cretaceous before eventually becoming extinct.
They were streamlined predators with large eyes, elongated jaws, and paddle-like limbs, capable of reaching high swimming speeds. Their diet likely consisted of fish, squid, and other marine organisms. Fossils of ichthyosaurs are particularly valued for their role in understanding early marine reptile evolution and Jurassic marine ecosystems.
Morphological Features of the Vertebrae
This specimen contains articulated vertebrae, meaning that several vertebral centra remain naturally connected in their original anatomical arrangement. Features include:
- Cylindrical vertebral centra, typical of ichthyosaurs.
- Well-preserved surface texture, showing bone structure detail.
- Natural articulation, adding scientific and display value.
- Preparation that highlights form without over-restoration.
Such fossils are far less common than isolated vertebrae, making this an especially valuable and desirable piece for collectors.
Collector and Scientific Significance
Ichthyosaur remains from the Lyme Regis–Charmouth stretch of coastline hold a special place in the history of palaeontology. Early discoveries here by pioneering fossil collectors, including Mary Anning, brought ichthyosaurs to the attention of science in the early 19th century.
An articulated vertebrae section such as this is highly prized for both scientific and educational use, providing insight into skeletal structure and preservation conditions of marine reptiles. For collectors, it represents not only a rare fossil but also a tangible link to the rich history of the Jurassic Coast.
A Rare Piece of the Jurassic Coast
Owning this Ichthyosaur articulated vertebrae fossil means holding a genuine piece of Earth’s natural history, preserved for nearly 200 million years. With its golden provenance from the Jurassic Coast, certified authenticity, and professional preparation, it makes a striking addition to any fossil collection, museum display, or educational resource.
All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.
