Rare Fossil Ammonite Toricellites lahuseni Jurassic Callovian Ashton Keynes UK | Authentic British Fossil

£60.00

This listing features a rare and scientifically important fossil of Toricellites lahuseni, an extinct ammonite species from the Callovian stage of the Middle Jurassic. The specimen comes from Ashton Keynes, Wiltshire, United Kingdom, a classic fossil locality within the English Oxford Clay Formation, known for its marine reptile and ammonite fauna.

Geological Context:

  • Fossil Type: Ammonite (Extinct marine mollusc, relative of modern squid and cuttlefish)
  • Species: Toricellites lahuseni (de Grossouvre, 1901)
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Tulitidae
  • Geological Stage: Callovian (c. 166.1 to 161.2 million years ago)
  • Formation: Oxford Clay Formation
  • Depositional Environment: Low-energy, shallow marine shelf with fine-grained clay-rich sediments

Toricellites is a genus valued for its transitional evolutionary features between earlier Stephanoceratoids and more derived ammonite lineages. Toricellites lahuseni is especially rare in the UK and contributes to the biostratigraphic framework of mid-Jurassic deposits in southern England.

Morphology & Notable Features:

  • Evolute shell with well-exposed whorls and open umbilicus
  • Strong, bifurcating ribs crossing the flanks with occasional tuberculation
  • Rounded venter without keel, typical of Tulitidae
  • Intricate suture patterns visible on well-preserved examples

Biozone Association: Toricellites lahuseni is most commonly associated with the Athleta Zone of the Middle Callovian, a key interval for ammonite-based stratigraphy across the UK and Europe.

Specimen Details:

  • Origin: Ashton Keynes, Wiltshire, United Kingdom
  • Age: Callovian Stage, Middle Jurassic (~163 million years old)
  • Scale: Scale rule square/cube = 1cm. Please see photographs for full dimensions
  • Condition: Professionally selected for preservation, completeness, and clarity
  • Photo: You will receive the exact fossil shown in the photographs

Certification & Authenticity: All of our fossils are 100% genuine and come with a Certificate of Authenticity. Each specimen is hand-selected for its scientific, educational, and collector value.

This rare Toricellites lahuseni ammonite from Wiltshire offers a fascinating glimpse into Britain’s Middle Jurassic seas—an ideal piece for collectors, educators, or palaeontological enthusiasts seeking a regionally significant fossil.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
