Rare Fossil Reptile Bone in Coprolite Bed Block – Aust Cliff, Upper Triassic UK, Penarth Group, Westbury Formation
Discover a genuine piece of deep-time history with this fossil reptile bone embedded in a block from the famous fish, reptile, and coprolite bed at Aust Cliff, Bristol. This exceptional specimen was recovered from the Westbury Formation of the Penarth Group, dating back to the Upper Triassic Period (~208-201 million years ago). It originates from one of the UK’s most iconic fossil sites, renowned for preserving an extraordinary mix of vertebrate remains in a rich depositional setting.
Your specimen was discovered on 07 April 2025 by our own expert field collectors, Alister and Alison, and meticulously cleaned, prepped, and preserved by Alison. The actual fossil you receive is the one shown in the photos, clearly scaled with a 1cm cube for accurate size reference.
This reptile bone likely belonged to one of the early marine or semi-aquatic reptiles known from the site, such as phytosaurs or early archosaurs, which thrived in estuarine and nearshore environments. The Westbury Formation was deposited in a low-energy marine lagoonal or marginal marine setting, perfect for fossil preservation.

A new fossil has been found at Blue Anchor, Somerset in the UK. The ichthyosaurs are not dinosaurs but evolved from other reptile species. They lived between the Mesozoic to Triassic era.
The species of the fossil is named:
Ichthyotitan severnensis
Other large ichthyosaur include
ichthyosaur Himalayasaurus tibetensis
ichthyosaur, Shonisaurus sikanniensis,
Ichthyosaurs were major components of Mesozoic marine ecosystems from the Early Triassic (Olenekian) until their extinction in the early Late Cretaceous (Cenomanian).
