For sale is an authentic Idoceras ammonite fossil from the Middle Oxfordian stage of the Jurassic Period, discovered in Charente, France. This beautifully preserved specimen displays the distinctive ribbed shell and coiled morphology characteristic of the Idoceras genus, making it a valuable addition to any fossil collection.

Geology & Fossil Type:

This ammonite comes from the Middle Oxfordian, a stage of the Upper Jurassic, dating back approximately 160 million years. The Oxfordian period was marked by widespread shallow seas, where ammonites thrived. These fossils play a crucial role in biostratigraphy, helping geologists date and correlate Jurassic rock layers.

Idoceras belonged to the subclass Ammonoidea, an extinct group of marine mollusks closely related to modern squids and octopuses. Ammonites were free-swimming marine creatures that used their chambered shells for buoyancy control, allowing them to move efficiently through prehistoric seas. The ribbed shell of Idoceras helped protect it from predators and provided structural support for deep-sea navigation.

  • 100% Genuine Fossil – No Replicas or Synthetics
  • Comes with a Certificate of Authenticity
  • From the Alice Purnell Collection, a highly regarded fossil collection
  • Scale cube = 1cm for size reference (please see photos for full dimensions)

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.
