Fossil Vertebra and Bone Fragments – Westbury Formation, Upper Triassic

Location: Aust Cliff, Bristol, United Kingdom

Geological Age: Upper Triassic (Rhaetian Stage, approx. 205 million years ago)

Stratigraphy: Westbury Formation, Penarth Group

This exceptional specimen comes from the renowned “fish, reptile and coprolite bed” at Aust Cliff, one of Britain’s most famous Late Triassic fossil sites. The matrix includes a fossilised vertebra and associated bone fragments, likely from small marine reptiles or bony fish that once thrived in the shallow marginal seas of the time.

Geological & Palaeontological Context:

  • Fossil Type: Vertebra and bone fragments
  • Possible Origin: Fish (e.g., Saurichthys, Ceratodus) or marine reptiles (e.g., early ichthyosaurs or placodonts)
  • Formation: Westbury Formation
  • Group: Penarth Group
  • Stage: Rhaetian (Upper Triassic)
  • Depositional Environment: Lagoonal to marginal marine with periodic anoxia, ideal for exceptional preservation
  • Biozone: Not formally zoned for vertebrates, but the layer is notable for containing numerous vertebrate remains
  • Notable Features: The bones exhibit preservation typical of vertebrate material from Aust Cliff—often dark brown or black due to phosphate mineralisation. Vertebrae are generally compressed or disk-shaped with smooth margins.

This fossil was discovered by our expert team members, Alister and Alison, on 07 April 2025. It has been professionally cleaned, prepped and treated by Alison to ensure its long-term preservation and display quality.

Scale & Presentation:

Scale cube = 1cm. Please see the photo for full sizing and specimen details. The photograph shows the exact item you will receive.

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.
