Plesiosaur Fossil Articulated Vertebrae Jurassic Blue Lias Somerset UK Watchet Marine Reptile Specimen COA Included

Description

Genuine Plesiosaur Articulated Vertebrae – Jurassic Marine Reptile Fossil from Somerset

Offered here is an exceptional and highly collectible Plesiosaur fossil articulated vertebrae specimen, preserved within the famous Blue Lias Formation of the Early Jurassic. This remarkable fossil comes from Watchet, Somerset, England, an important coastal locality well known for marine reptile discoveries.

Unlike isolated bone fragments, articulated vertebrae are especially sought after because they preserve multiple spinal elements in natural connection, providing a rare and visually impressive glimpse into the skeletal anatomy of these ancient marine reptiles.

This is a carefully chosen piece, selected for its strong preservation, authenticity, and outstanding display quality. The photographs show the exact specimen you will receive, with full sizing clearly visible in the provided images.

Every fossil we offer is a genuine specimen, and this marine reptile fossil includes a Certificate of Authenticity with lifetime guarantee, supplied as a generic authenticity card for permanent documentation and buyer confidence.

Importantly, this specimen was discovered by our own experienced team members, Alister and Alison, on 21 December 2025, and has been professionally cleaned, prepped, and treated by Alison, ensuring excellent presentation and long-term stability.

Geological Setting – Blue Lias Formation, Early Jurassic

This fossil originates from the famous Blue Lias Formation, dating to approximately 200 million years ago, during the Early Jurassic. The Blue Lias is renowned throughout the UK for its alternating limestone and shale layers, deposited in a warm, shallow marine environment rich in life.

During this period, Somerset lay beneath an ancient sea filled with ammonites, belemnites, fish, and large marine reptiles. The quiet seabed conditions allowed carcasses to settle, become buried by fine sediments, and fossilise in remarkable detail.

Watchet and the Somerset coast are historically significant fossil hunting areas, producing important marine reptile remains for both collectors and scientific study.

Fossil Species – Plesiosaur Marine Reptile Vertebrae

Plesiosaurs were powerful marine reptiles belonging to the order Plesiosauria, famous for their long necks, paddle-like limbs, and predatory lifestyle. They were among the dominant hunters of Jurassic oceans, feeding on fish and cephalopods.

This specimen consists of articulated vertebrae, meaning the spinal bones are preserved together in life position. Vertebrae fossils provide valuable insight into the structure, flexibility, and size of these prehistoric animals.

Articulated plesiosaur remains are significantly rarer than isolated bones, making this a particularly desirable fossil for collectors seeking something more anatomically complete.

Preservation and Fossil Features

The vertebrae retain their natural fossilised bone structure, with authentic surface texture and Jurassic mineralisation from burial within the Blue Lias sediments. The specimen has been carefully prepared to highlight the vertebral shapes while maintaining the integrity of the surrounding matrix.

Professional preparation by Alison ensures the fossil is stable, well presented, and suitable for long-term collecting or display. Such specimens make outstanding centrepieces for any marine reptile or Jurassic fossil collection.

Authenticity and Provenance

This is a 100% genuine articulated Plesiosaur vertebrae fossil, responsibly collected from Watchet, Somerset by Alister and Alison, and expertly cleaned, prepped, and treated by Alison.

A lifetime Certificate of Authenticity is included, ensuring full confidence in provenance and genuineness.
