JPY ¥7890.00

For sale is an authentic Aulacosphinctes ammonite fossil from the Middle Oxfordian stage of the Jurassic Period, discovered in Charente, France. This beautifully preserved fossil showcases the characteristic ribbed shell structure of the Aulacosphinctes genus, an extinct ammonite group that thrived in ancient marine environments over 160 million years ago.

Geology & Fossil Type:

This ammonite comes from the Middle Oxfordian, a stage of the Upper Jurassic, a time when vast shallow seas covered much of what is now Europe. The Oxfordian stage is well known for its rich ammonite faunas, providing insight into the marine biodiversity of the Jurassic seas. Fossils from Charente, France, are particularly significant due to their excellent preservation and geological importance.

Ammonites like Aulacosphinctes belonged to the subclass Ammonoidea, a group of extinct marine mollusks closely related to modern squids and octopuses. Their coiled, chambered shells allowed for buoyancy control, making them efficient swimmers in the Jurassic oceans. The ribbed shell of Aulacosphinctes is a distinguishing feature, helping paleontologists identify different species and track evolutionary changes through the Jurassic period.

Fossil Details:

  • 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)
  • You will receive the exact specimen shown in the listing

This rare and scientifically valuable ammonite fossil is a must-have for collectors, educators, paleontology enthusiasts, and fossil lovers. Whether displayed as a striking natural history piece or studied for its geological significance, this Aulacosphinctes ammonite is an exceptional Jurassic-era treasure.

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.
