Original price was: £36.00.Current price is: £32.40.

A stunning and rare Large Fossil Fish Bone Section with fins, preserved in matrix from the famous fish, reptile, and coprolite bed at Aust Cliff, near Bristol, UK. This exceptional vertebrate fossil was discovered by our field experts Alister and Alison on 07 April 2025, and has been meticulously cleaned, prepped, and treated by Alison to a high standard.

Collected from the Westbury Formation, part of the Penarth Group, this specimen dates to the Rhaetian Stage of the Upper Triassic Period (circa 208–201 million years ago). The Aust Cliff site is internationally recognised for yielding vertebrate-rich deposits including fish, early marine reptiles, and trace fossils.

This block contains a well-preserved section of a large fish skeleton, including discernible fin rays and bone structures, which may belong to a predatory neopterygian or a large actinopterygian such as Saurichthys. The fossil provides valuable insight into the anatomy and ecosystem of Late Triassic marine life and is particularly suited for educational or research use, as well as display.

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.
