Ichthyosaur Reptile Fossil Vertebra Black Ven Lyme Regis Jurassic Coast UK Genuine Specimen with Certificate of Authenticity

Description

Authentic Ichthyosaur Fossil Vertebra from the Jurassic Coast

This genuine Ichthyosaur Reptile Fossil Vertebra was collected from the well-known Black Ven Marls, Lower Lias, along the world-famous Jurassic Coast at Black Ven, Lyme Regis, Dorset, UK. Ichthyosaurs were fast-swimming marine reptiles that lived during the Early Jurassic, and their fossils are among the most iconic and scientifically important remains found along this coastline. This vertebra is a beautifully preserved example, showing the classic cylindrical form that defines ichthyosaur spinal elements.

Geological Background: Lower Lias, Early Jurassic

Dating to approximately 200 million years ago, the Lower Lias is one of the most fossil-rich sequences of the Early Jurassic period. The Black Ven Marls formed in a calm marine basin where fine mudstone sediments accumulated rapidly, burying and preserving a wide range of marine life. This environment supported large populations of ammonites, fish, marine reptiles, and other organisms, many of which are found today as exceptionally preserved fossils.

Ichthyosaurs were among the dominant predators in these ancient seas, occupying a role similar to modern dolphins and predatory fish. Their streamlined bodies, large eyes, and powerful tails made them agile hunters well adapted to the open marine environment. Fossils from Black Ven provide critical evidence for the anatomy, lifestyle, and evolutionary history of these remarkable reptiles.

Morphology and Notable Features of the Vertebra

This specimen displays the key features characteristic of ichthyosaur vertebrae:

• A robust, disc-shaped centrum with smooth lateral surfaces
• Clearly defined concave (amphicoelous) articulation surfaces typical of marine reptiles
• Fine bone texture preserved along the outer edges
• Symmetrical form ideal for anatomical study or display
• Stable, naturally mineralised composition resulting from millions of years of fossilisation

The amphicoelous shape of the vertebra indicates strong flexibility in the spinal column, a trait that contributed to the ichthyosaur’s powerful swimming ability. Such vertebrae form an important part of understanding locomotion and skeletal structure in these ancient marine reptiles.

Depositional Environment and Preservation

The mudstone matrix of the Black Ven Marls provided exceptional preservation, protecting delicate skeletal elements from extensive erosion. Over millions of years, mineral-rich sediments replaced organic bone material with stable fossil minerals, preserving fine structural details. This vertebra retains its natural textures and shape, providing an authentic glimpse into Early Jurassic marine life.

Because the fossil was collected before coastal erosion could damage it, it remains well-defined and suitable for scientific interpretation, educational use, or display.
