RARE Fossil Reptile Bone – Westbury Formation, Aust Cliff, Upper Triassic, UK

This listing is for a genuine fossilised reptile bone preserved within a natural matrix from the famous fish, reptile, and coprolite bed of Aust Cliff, Bristol, UK. This rare and historically significant site is part of the Westbury Formation within the Penarth Group, dating to the Upper Triassic period (approx. 208–201 million years ago).

Your specimen was carefully discovered by our own team members Alister and Alison on 07 April 2025, and has been professionally cleaned, prepped, and treated by Alison to ensure both preservation and presentation quality.

The Westbury Formation at Aust Cliff represents a transitional coastal lagoonal to marginal marine depositional environment. Fossils found here are often associated with the Rhaetian Stage of the Upper Triassic, making them invaluable for understanding the pre-Jurassic marine and nearshore fauna of the UK.

The bone is likely to be from a marine or semi-aquatic reptile, with known species from this bed including Ichthyosaurs, Plesiosaurs, and primitive Crocodyliforms. While exact taxonomic assignment is not possible without further scientific analysis, the morphology is consistent with vertebrate skeletal remains from these groups.

Triassic Information

The Triassic Period (252–201 million years ago) marked the beginning of the Mesozoic Era, following the Permian-Triassic mass extinction, the most severe extinction event in Earth's history. The climate was hot and dry, with vast deserts and little polar ice. Life slowly recovered, leading to the rise of the first dinosaurs, pterosaurs (flying reptiles), and early mammals. Reptiles, including large archosaurs (ancestors of crocodiles and dinosaurs), dominated both land and sea. In the oceans, ichthyosaurs and plesiosaurs thrived alongside ammonites and early coral reefs. The first true conifers and ginkgo trees spread across the land. The period ended with another mass extinction, paving the way for the Jurassic and the golden age of dinosaurs.
