Fossil Ceratodus Coprolite – Triassic Westbury Formation – Aust Cliff Bristol UK – Genuine with Certificate

Description

An authentic Fossil Ceratodus Coprolite from the famous fish, reptile, and coprolite bed at Aust Cliff, near Bristol, UK. This remarkable specimen was discovered on 07 April 2025 by our experienced field team, Alister and Alison, and has been carefully cleaned, prepped, and treated by Alison.

This coprolite comes from the Westbury Formation, part of the Penarth Group, which dates to the Upper Triassic Period, specifically the Rhaetian Stage, around 208 to 201 million years ago. Aust Cliff is one of the most important Late Triassic sites in the UK, with rich fossil layers known for yielding vertebrate remains including fish, early marine reptiles, and a variety of coprolites.

The coprolite (fossilized excrement) likely originated from a Ceratodus, a genus of prehistoric lungfish. These coprolites are often found in claystone or marl-rich blocks, representing ancient nearshore lagoon or estuarine environments. This specimen preserves natural shape, texture, and structure, giving valuable insight into the diet and ecology of early vertebrates.

The fossil has been professionally photographed with a 1 cm scale cube, and the image shows the exact specimen you will receive.
