Polished Fossil Slab – Fish, Shark, Reptile Bone & Coprolite, Aust Cliff UK, Triassic Period

Original price was: £24.00.Current price is: £21.60.

Presenting a rare and scientifically significant Polished Slab of Fossil Fish, Shark Bone, Reptile Bone, and Coprolite from the Westbury Formation, part of the Penarth Group, dated to the Upper Triassic (Rhaetian) approximately 208–201 million years ago. This exceptional piece was sourced from Aust Cliff, near Bristol, United Kingdom, a world-famous Triassic fossil locality.

The slab contains a unique fossil assemblage including:

  • Fragmented fish bones and scales
  • Shark and marine reptile bone fragments
  • Abundant coprolites (fossilised faeces), often spiral or rounded in morphology

All fossil components are preserved within a dark, fine-grained sedimentary matrix and have been expertly polished on one surface to reveal the textures, inclusions, and contrast of this fossil bed.

Fossil Type: Multi-species fossil bed including vertebrate remains and trace fossils (coprolites)

Geological Age: Upper Triassic – Rhaetian Stage

Formation: Westbury Formation

Group: Penarth Group

Depositional Environment: Formed in a coastal lagoonal or shallow marine setting with fluctuating salinity and periodic anoxic events. The Westbury Formation is known for bone beds where marine vertebrates and organic debris accumulated and were rapidly buried in low-oxygen sediments, aiding exceptional preservation.

Morphological Features:

  • Irregular fragments of fish and reptile bone, embedded in matrix
  • Rounded and spiral coprolites of varying sizes
  • Polished surface highlights bone textures and organic inclusions

Notable:

  • Authentic slab from Aust Cliff, one of the most famous Upper Triassic sites in the UK
  • Displays diverse fossil content in a single polished surface
  • Excellent for collectors, museums, academic study, or decorative purposes
  • The actual specimen shown in the listing photograph

Authenticity: All of our fossils are 100% genuine natural specimens and come with a Certificate of Authenticity. The item photographed is the exact specimen you will receive. Each cube or square in the scale represents 1cm – please refer to the image for full sizing.

 

This Polished Fossil Slab from Aust Cliff offers a fascinating snapshot of life in the waning years of the Triassic period, preserved within the storied sediments of the Westbury Formation. A rare and beautiful piece for any serious collector or enthusiast.

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.
