GENUINE ICHTHYOSAUR CORACOID BONE FOSSIL BLOCK

This listing is for a genuine ichthyosaur coracoid bone fossil preserved in a
block from the famous fish, reptile and coprolite bed at Aust Cliff, Bristol, UK. The specimen comes from the Westbury Formation, part of the Penarth Group, and dates to the Upper Triassic. This is a carefully chosen fossil piece, with the photograph showing the actual specimen you will receive. Full sizing and scale details can be seen in the photo.

Your specimen was discovered by our own team members, Alister and Alison, and has been carefully cleaned, prepped and treated by Alison. It is supplied with a Certificate of Authenticity lifetime guarantee generic card, confirming that this is a genuine fossil specimen and making it a highly interesting piece for collectors of British fossils, marine reptile fossils, Triassic vertebrate material and natural history display specimens.

ABOUT ICHTHYOSAURS

Ichthyosaurs were extinct marine reptiles that lived throughout much of the Mesozoic Era. Although they resembled dolphins or large fish in overall body shape, they were reptiles that became highly adapted to life in the sea. They had streamlined bodies, powerful tails, large eyes, paddle-like limbs and a predatory lifestyle, feeding on fish, squid-like animals and other marine prey.

Ichthyosaurs were among the most successful marine reptiles of the Triassic and Jurassic periods. Early forms appeared during the Triassic, and by the later Triassic they had become an important part of marine ecosystems. Fossil material from ichthyosaurs is especially collectable because it represents large prehistoric marine reptiles rather than more commonly found invertebrate fossils.

CORACOID BONE ANATOMY

The coracoid is a bone from the shoulder girdle. In ichthyosaurs, the shoulder girdle helped support the forelimbs, which had evolved into strong paddle-like flippers used for steering and movement through the water. A coracoid bone fossil is therefore an important anatomical element, linked directly to the swimming adaptations of these prehistoric marine reptiles.

Ichthyosaur coracoids are usually broad, plate-like bones rather than long limb bones. Their shape helped form part of the structural framework for the forelimb, connecting with other shoulder elements such as the scapula and helping support the powerful front paddle. A coracoid preserved in matrix is particularly appealing because it retains the natural setting of the fossil-bearing bed, giving the specimen strong geological character and display interest.

AUST CLIFF FISH, REPTILE AND COPROLITE BED

Aust Cliff, near Bristol, is one of Britain’s classic fossil localities for Upper Triassic vertebrate fossils. It is especially famous for its fish, reptile and coprolite bed, a fossil-rich bone bed that has produced a wide variety of remains including reptile bones, fish teeth, shark material, scales, fin spines, coprolites and other durable hard parts from ancient marine animals.

This ichthyosaur coracoid bone comes from a block associated with that famous fossil horizon. Bone bed material is highly collectable because it preserves a natural concentration of fossil remains from an ancient environment. These blocks offer a glimpse into the Late Triassic seabed, where bones, teeth and other hard remains accumulated before being buried and fossilised.

WESTBURY FORMATION AND PENARTH GROUP

The fossil comes from the Westbury Formation of the Penarth Group, a geological unit associated with the latest part of the Triassic Period. These deposits are commonly linked with the Rhaetian Stage of the Upper Triassic, shortly before the beginning of the Jurassic Period.

During this time, the area that is now Aust Cliff formed part of a shallow marine to coastal environment. Changing sea levels, currents and storm activity helped concentrate resistant remains such as bones, teeth, scales and coprolites into fossil-rich layers. Over millions of years, these remains became preserved in the rock, forming the well-known bone beds that are now studied and collected for their important record of Late Triassic marine life.

COLLECTABLE BRITISH MARINE REPTILE FOSSIL

This ichthyosaur coracoid bone fossil from Aust Cliff is a desirable specimen for collectors of British fossils, Triassic fossils, marine reptile fossils, ichthyosaur bones, vertebrate fossils and natural history display pieces. Its provenance from Aust Cliff, Bristol, together with the Westbury Formation and Penarth Group origin, gives it strong geological context and excellent collectable appeal.

The specimen has been carefully selected for its authenticity, natural appearance and connection to one of the UK’s most famous Triassic bone bed localities. As the photograph shows the exact fossil supplied, you can buy with confidence knowing precisely which piece will be received. With its genuine Upper Triassic age, classic British locality, matrix block preservation and included Certificate of Authenticity lifetime guarantee generic card, this ichthyosaur coracoid bone fossil offers a direct connection to the ancient marine reptiles of prehistoric Britain.
