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

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

TWD NT$1049.00

This listing offers a rare and scientifically valuable fossil of Toricellites lahuseni, a distinct ammonite species from the Middle Callovian stage of the Jurassic period. The fossil was discovered near Ashton Keynes, Wiltshire, United Kingdom, a locality with marine clay and limestone beds that yield beautifully preserved mid-Jurassic cephalopods.

Geological Context:

  • Fossil Type: Ammonite (Extinct marine mollusc, relative of squid and cuttlefish)
  • Species: Toricellites lahuseni (identified by de Grossouvre, 1901)
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Tulitidae
  • Geological Stage: Middle Callovian (c. 165.3 to 161.2 million years ago)
  • Formation: Oxford Clay or correlative Callovian marine beds
  • Depositional Environment: Shallow marine shelf, rich in clayey carbonate sedimentation

Torricellites ammonites are notable for their transitional features between earlier Stephanoceratoids and later Perisphinctoids. T. lahuseni is particularly rare and valuable in biostratigraphic and evolutionary studies, often recovered from finely laminated marine clays in southern England.

Morphology & Notable Features:

  • Moderately evolute shell with open umbilicus
  • Finely ribbed flanks with uniform or faintly bifurcating ribs
  • Rounded to slightly keeled venter depending on growth stage
  • Complex suture lines typical of mid-Jurassic ammonites
  • Rare species, infrequently encountered in the fossil market

Biozone Association: Toricellites lahuseni is associated with the Athleta Zone of the Middle Callovian and provides valuable data for zonal correlation in UK and European Jurassic marine stratigraphy.

Specimen Details:

  • Origin: Ashton Keynes, Wiltshire, United Kingdom
  • Age: Middle Callovian Stage, Jurassic (~163 million years old)
  • Scale: Scale rule square/cube = 1cm. Please see photo for accurate sizing
  • Condition: Chosen for its preservation and completeness
  • Photo: The specimen shown is the exact fossil you will receive

Certification & Authenticity: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity. Every piece is hand-selected with care to ensure scientific integrity and collector appeal.

This rare Toricellites lahuseni ammonite offers a unique glimpse into Britain’s Jurassic marine history. A standout specimen for serious collectors, palaeontologists, or anyone passionate about natural history.

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.
