Fossil Fish Tooth in Matrix – Upper Triassic – Aust Cliff, Westbury Formation, Penarth Group, Bristol, UK

This listing features an authentic fossil fish tooth preserved in matrix, originating from the iconic fossil-bearing bed at Aust Cliff, Bristol. This site is internationally recognised for its rich accumulation of fish, reptile, and coprolite remains from the Upper Triassic period, particularly within the Westbury Formation of the Penarth Group.

Geological & Scientific Context:

  • Locality: Aust Cliff, Bristol, UK
  • Stratigraphy: Westbury Formation, Penarth Group
  • Age: Upper Triassic (~205–210 million years ago)
  • Depositional Environment: A marginal marine estuarine or coastal lagoon setting with periodic anoxic conditions. These created ideal preservation conditions, capturing a moment in time from a biologically diverse late Triassic ecosystem.
  • Lithology: Laminated, organic-rich black mudstones with bone and tooth-rich concentrations

Fossil Description & Features:

The specimen displays a clearly defined fish tooth embedded within a natural matrix, offering a glimpse into the feeding anatomy of prehistoric fishes. Likely candidates for attribution include Saurichthys, Lepidotes, or Palaeoniscid fish—all of which are known from this formation.

  • Morphology:
  • Conical or lanceolate shape typical of piscivorous species
  • Smooth enamel surface, occasionally striated, with tapering to a fine point
  • Root occasionally visible, though often encased in matrix
  • Palaeontological Significance:
  • Teeth from this bed are essential in studying the evolution and dietary adaptations of early ray-finned fishes and predatory actinopterygians
  • The fossil record from Aust Cliff helps reconstruct the dynamics of Triassic vertebrate communities just before the major Jurassic radiation

Specimen Details:

  • Discovery Date: 07 April 2025
  • Discovered by: Our own field team members, Alister and Alison
  • Preparation & Treatment: Cleaned and stabilised by Alison
  • Scale Reference: Shown with 1cm cube – please refer to photographs for full sizing and angles
  • Authenticity: Comes with a Certificate of Authenticity – all of our fossils are 100% genuine and responsibly sourced
  • What You See Is What You Get: The specimen in the photos is the exact item you’ll receive

Ideal For:

Fossil collectors, educational purposes, museum displays, or anyone with a fascination for marine vertebrates of the prehistoric world. This specimen makes a superb addition to collections focused on Triassic ecosystems, vertebrate paleontology, or evolutionary biology.

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.
