Key Geological and Scientific Information:

  • Species: Kepplerites gowerianus
  • Fossil Type: Ammonite (extinct marine cephalopod)
  • Geological Period: Jurassic
  • Geological Stage: Lower Callovian (Middle Jurassic)
  • Location: Waterpark, Ashton Keynes, Wiltshire, England, UK
  • Formation: Likely Kellaways Beds or closely associated Callovian clays
  • Approximate Age: ~164 million years ago
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Kosmoceratidae
  • Formally Described By: Sowerby (1836)

 

Morphology Features: Kepplerites gowerianus exhibits a moderately involute shell with distinct bifurcating ribbing and a gently rounded venter. Compared to other Kepplerites species, gowerianus often displays more robust ribbing and a broader umbilical area, making it a diagnostic and striking example of Lower Callovian ammonites.

 

Depositional Environment: The fossil was deposited in low-energy, offshore marine environments, typical of the Callovian transgressive systems. Fine-grained sediments like silts and mudstones helped preserve delicate shell details and make Ashton Keynes a notable fossil locality.

 

Biozone & Stratigraphic Significance: Kepplerites gowerianus is often found just above or in association with the Kepplerites galilaeii Biozone, offering finer resolution within the Lower Callovian stratigraphy. Its occurrence aids in ammonite zonation and Jurassic correlation in Europe.

 

Scientific Importance: The genus Kepplerites plays a central role in Jurassic biostratigraphy, and gowerianus represents a morphologically distinctive and biostratigraphically valuable member of that group. This specimen is both a research-worthy and display-worthy fossil.

 

Authenticity Guarantee: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity. This specimen has been expertly sourced, cleaned, and prepared to preserve its natural features.

 

This rare Kepplerites gowerianus ammonite is a premium addition to any fossil or scientific collection — a real piece of Jurassic history from one of the UK’s finest fossil-bearing localities.

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.
