Presenting a RARE 5″ Fossil Ammonite of Kepplerites galilaeii, a scientifically important and visually impressive specimen from the Lower Callovian Stage of the Jurassic Period, found at Waterpark, Ashton Keynes, United Kingdom. This ammonite is a highly sought-after piece due to its size, preservation, and biostratigraphic importance.

The fossil you see in the photographs is the exact specimen you will receive, carefully selected and presented with full transparency.

Scale Rule Squares / Cube = 1cm — please refer to the photographs for complete sizing and visual reference.

 

Key Geological and Scientific Information:

  • Species: Kepplerites galilaeii
  • Fossil Type: Ammonite (extinct marine cephalopod)
  • Geological Period: Jurassic
  • Geological Stage: Lower Callovian (Middle Jurassic)
  • Location: Waterpark, Ashton Keynes, Wiltshire, England, UK
  • Formation: Likely part of the Kellaways Beds within the Callovian sequence
  • Approximate Age: ~164 million years old
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Kosmoceratidae
  • Described By: d’Orbigny

 

Morphology Features: This large Kepplerites galilaeii specimen features classic characteristics of the species: a moderately involute shell with strong, bifurcating ribbing and a rounded venter. Ribbing initiates from umbilical tubercles and spreads outward in a regular pattern. These morphological traits are well-preserved in this piece, making it both scientifically valuable and visually captivating.

 

Depositional Environment: The fossil originates from offshore marine sediments typical of the Callovian marine transgression. These low-energy, mid- to outer-shelf environments preserved ammonites like Kepplerites galilaeii in excellent condition within fine-grained sediments such as claystone and silty marl.

 

Biozone & Stratigraphic Importance: Kepplerites galilaeii defines the Kepplerites galilaeii Zone, a major ammonite biozone used across Europe for the Lower Callovian. Its presence allows for precise stratigraphic correlation between regions and represents a pivotal marker in Jurassic paleontology.

 

Scientific Importance: As the zone-defining species, Kepplerites galilaeii is a critical fossil in the study of Jurassic ammonite biostratigraphy. Its distribution and features provide valuable insight into cephalopod evolution and paleobiogeography during the Middle Jurassic.

 

Authenticity Guarantee: All our fossils are 100% genuine specimens. This ammonite has been carefully selected for its scientific and aesthetic qualities and comes complete with a Certificate of Authenticity.

 

Don’t miss the opportunity to own this remarkable and rare Kepplerites galilaeii ammonite — a centrepiece for any fossil collection or a standout scientific specimen from the United Kingdom’s rich Jurassic 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.
