RARE 7″ Quenstedtoceras dissimili Fossil Ammonite – Callovian, Jurassic, Shorncote UK – Genuine Specimen COA

Original price was: £132.00.Current price is: £118.80.

Available here is a magnificent 7-inch specimen of Quenstedtoceras dissimili, a rare and striking fossil ammonite from the Callovian stage of the Jurassic Period, sourced from Shorncote Quarry, Gloucestershire, United Kingdom. This piece is part of the prestigious Alice Purnell Collection, with the photograph showing the exact fossil you will receive.

Geological Context:

  • Species: Quenstedtoceras dissimili
  • Geological Period: Jurassic
  • Stage: Callovian (~166 – 163 million years ago)
  • Stratigraphy: Upper Cornbrash Formation (limestones and marls)
  • Location: Shorncote Quarry, Gloucestershire, UK
  • Depositional Environment: Shallow epicontinental marine shelf with carbonate sedimentation and intermittent siliciclastic influx; associated with warm, nutrient-rich waters.

Taxonomic Classification:

  • Family: Cardioceratidae
  • Superfamily: Stephanoceratoidea
  • Order: Ammonitida

Morphology Features: Quenstedtoceras dissimili is known for its evolute shell, prominent bifurcating ribbing, and occasional tuberculate ornamentation along the ventrolateral margins. The suture lines are complex and pronounced, a hallmark of the genus. This specimen beautifully illustrates these features, making it ideal for both collectors and educational purposes.

Notability: Quenstedtoceras is a key zonal genus in the Middle to Late Jurassic, with Q. dissimili often used for precise biostratigraphic correlation within the Callovian. Fossils from Shorncote are increasingly rare due to limited access and exposure, making this piece particularly desirable.

Additional Details:

  • All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.
  • Scale Rule Squares / Cube = 1cm: Refer to the photo for full sizing.
  • From the trusted Alice Purnell Collection – a fossil with provenance.

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.
