A beautifully preserved and scientifically intriguing Cadoceras sublaeve ammonite fossil from the Lower Callovian stage of the Jurassic period, found in Normandy, France. This piece showcases the intricate shell structure and serves as both a collector’s item and a window into Jurassic marine ecosystems.

As with all our specimens, this is a 100% genuine fossil, carefully chosen for quality and authenticity, and includes a Certificate of Authenticity. The actual specimen is photographed, shown with a 1cm scale cube for accurate sizing—please refer to the photo for full measurements.

Geological & Scientific Information:

  • Species: Cadoceras sublaeve
  • Type: Fossil Ammonite (extinct cephalopod)
  • Age: Approx. 165 million years old
  • Geological Period: Jurassic
  • Stage: Lower Callovian
  • Formation: Likely part of the Calcaire à Bélemnites / equivalent regional marine limestone formations
  • Location Found: Normandy, France
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Cardioceratidae
  • Morphological Features: Involute shell with rounded whorls and fine ribbing, the typical morphology of Cadoceras includes pronounced, evenly spaced ribs and a moderately depressed whorl cross-section. This specimen exhibits exceptional preservation of surface detail and sutures.
  • Depositional Environment: Open marine, mid-shelf environment with low-energy conditions conducive to fine sediment deposition and fossil preservation.
  • Scientific Importance: Cadoceras is a key biostratigraphic genus in the Callovian, helping define zones within the Middle Jurassic. It is particularly important in the Boreal Realm correlations and European Jurassic stratigraphy.

Additional Notes:

Cadoceras ammonites are highly sought after for their elegant ribbed structure and paleontological significance. This fossil from Normandy is an ideal representative of Middle Jurassic marine life and makes a compelling display or educational piece.

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.
