This listing is for a Rare Fossil Ammonite (Orthosphinctes tiziani) from the Middle Oxfordian Stage of the Late Jurassic, discovered at Le Vanneau, Deux-Sèvres, France.

100% Genuine Fossil Specimen – All of our fossils are authentic and come with a Certificate of Authenticity.

Exact Specimen Shown – The photos provided are of the actual fossil you will receive.

Scale for Reference – Scale rule squares/cube = 1cm. Please see photos for full sizing.

 

Geological & Scientific Details:

  • Fossil Type: Ammonite (extinct marine mollusc, related to squid and octopus).
  • Species: Orthosphinctes tiziani.
  • Order: Ammonitida.
  • Superfamily: Perisphinctoidea.
  • Family: Perisphinctidae.
  • Geological Period: Jurassic.
  • Stage/Age: Middle Oxfordian (approx. 163 – 157 million years ago).
  • Locality: Le Vanneau, Deux-Sèvres, France.

 

Notable Features & Morphology:

  • Shell Form: Evolute shell with widely open coiling, exposing inner whorls.
  • Ribs: Strong, bifurcating ribs typical of Orthosphinctes, creating a bold ornamental pattern.
  • Whorl Section: Rounded to slightly compressed, giving the ammonite a striking appearance.
  • Size: A rare, well-preserved specimen, highly collectible for display or research.

 

Depositional Environment:

During the Oxfordian, western France was submerged beneath shallow epicontinental seas. Warm, carbonate-rich marine conditions led to excellent preservation of ammonites and other marine organisms within limestone and marl deposits.

 

Scientific & Collecting Importance:

Orthosphinctes tiziani is an important ammonite species for biostratigraphic correlation in the Oxfordian. Its diagnostic ribbing and characteristic shell morphology make it an essential index fossil and a prized specimen for collectors.

 

Why Buy This Fossil?

  • A rare ammonite species from the Oxfordian of France.
  • Excellent preservation with bold ribbing and characteristic form.
  • An outstanding specimen for collectors of Jurassic ammonites or European fossils.
  • Supplied with a Certificate of Authenticity guaranteeing its provenance.

 

All of our fossils are responsibly sourced, carefully prepared, and chosen for quality.

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.
