Genuine Plesiosaur Rib Fossil – Jurassic Marine Reptile Bone from Dorset, UK

Offered here is an authentic Plesiosaur fossil reptile rib section, collected from the world-famous Black Ven Marls of the Lower Lias Formation, along the iconic Jurassic Coast of Dorset, England. This specimen comes from Black Ven, Charmouth, Lyme Regis, one of the most important marine reptile fossil localities in Europe.

This is a carefully chosen fossil bone piece, selected for its clear preservation, natural fossil character, and strong display appeal. 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 complete buyer confidence.

This specimen has been professionally cleaned, prepped, and treated by Alison, ensuring long-term stability and excellent presentation.

Geological Setting – Black Ven Marls, Lower Lias

This fossil originates from the famous Black Ven Marls, part of the Lower Lias Group, dating to the Early Jurassic approximately 190–200 million years ago. During this period, Dorset was submerged beneath a warm, shallow sea that supported an extraordinary diversity of marine life.

The Jurassic seas of Lyme Regis were home to ammonites, belemnites, fish, and spectacular marine reptiles such as ichthyosaurs and plesiosaurs. The fine muds and marls of Black Ven were deposited in relatively low-energy offshore conditions, allowing skeletal material to be buried and preserved in remarkable detail.

Black Ven is internationally recognised as one of the richest marine reptile fossil sites in the world, making fossils from this locality highly collectible and scientifically important.

Fossil Species – Plesiosaur Marine Reptile Rib Bone

Plesiosaurs were large, long-necked marine reptiles belonging to the order Plesiosauria, apex predators that ruled Jurassic seas alongside ichthyosaurs. They possessed powerful paddle-like limbs for swimming and were adapted to hunting fish and cephalopods in open marine environments.

This fossil represents a rib bone section, part of the supportive skeletal framework of these remarkable prehistoric reptiles. Rib fossils are highly valued because they offer a direct connection to the anatomy of these ancient creatures and provide an excellent example of genuine marine reptile bone.

Fragments such as this are often found within the Lower Lias marine sediments, preserved as durable fossilised bone within the marl matrix.

Preservation and Fossil Features

This specimen retains the natural dense bone structure typical of plesiosaur remains, fossilised over millions of years. The surface texture and coloration reflect its burial within the Jurassic marls, giving the fossil an authentic and historic appearance.

Prepared carefully by Alison, the rib section has been cleaned to highlight its form while maintaining its genuine geological character. Fossil marine reptile bones from Lyme Regis are increasingly scarce, making such pieces highly desirable for collectors and educational displays.

Authenticity and Collector Confidence

This is a 100% genuine Plesiosaur rib fossil, responsibly sourced from the Dorset Jurassic Coast.

It includes a lifetime Certificate of Authenticity, ensuring confidence in provenance and authenticity for collectors, educators, and gift buyers alike.

Ideal For Collectors, Displays and Gifts

This fossil is perfect for:

  • Marine reptile and Jurassic fossil collectors
  • Lyme Regis and Charmouth Jurassic Coast enthusiasts
  • Natural history and geology displays
  • Educational specimens for teaching prehistoric life
  • Unique prehistoric gifts with real provenance

A rare opportunity to own a genuine Plesiosaur rib bone fossil from the legendary Black Ven Marls of Dorset, preserved from an ancient sea nearly 200 million years old.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
