RARE Fossil Ammonite – Rugiferites rugifer

Middle Bathonian Stage, Jurassic Period – Niort Region, Deux-Sèvres, France

This listing features a rare and beautifully preserved fossil ammonite belonging to the species Rugiferites rugifer, from the Middle Bathonian of the Jurassic Period. Discovered in the Niort region of western France, this specimen represents a scarce and scientifically significant ammonite genus and is a striking addition to any collection.

Geological and Palaeontological Context:

  • Scientific Name: Rugiferites rugifer
  • Geological Period: Jurassic
  • Stage: Middle Bathonian (approx. 168–166 million years ago)
  • Location Found: Niort, Deux-Sèvres, France
  • Formation/Depositional Environment: Likely from a shallow marine shelf environment with clay- and marl-rich substrates. These settings supported diverse cephalopod faunas.
  • Lithology: Typically associated with fine-grained marls and silty limestones of the Bathonian in western France.

Taxonomy:

  • Kingdom: Animalia
  • Phylum: Mollusca
  • Class: Cephalopoda
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Perisphinctidae
  • Genus: Rugiferites
  • Species: Rugiferites rugifer
  • Identification Authority: Described by d’Orbigny (1850s), with subsequent classification refinement in regional Bathonian ammonite literature.

Morphology & Notable Features:

  • Strong ribbing across the whorls is typical of Rugiferites rugifer, often exhibiting coarse ornamentation and a compressed shell profile.
  • Shell shape is evolute, with all whorls clearly visible and uncoiled.
  • Tubercles and keels may be subtly developed, aiding in identification and differentiation from other Bathonian ammonites.
  • This specimen retains excellent preservation of the ribbing and overall coiling structure.

Biozone Information:

While Rugiferites rugifer is found within the Middle Bathonian interval, it is often associated with the Morrisi Zone and Retrocostatum Subzone in Western European ammonite stratigraphy. It is considered a useful index fossil for this part of the Bathonian sequence in France.

Collectible Significance:

Rugiferites rugifer is less commonly available than other Bathonian ammonites due to limited exposure of productive sites. Its strong ribbing and distinctive morphology make it both scientifically valuable and visually impressive for collectors. Specimens from Niort are especially prized due to their clarity and stratigraphic context.

Specimen Information:

  • Scale Reference: Scale cube in photo = 1cm
  • Authenticity: 100% Genuine Fossil – Not a replica
  • Certificate: Comes with a Certificate of Authenticity
  • Condition: Naturally preserved and professionally prepared
  • Photo: You will receive the exact fossil pictured

Summary:

This is a scientifically notable and visually attractive fossil of Rugiferites rugifer, a rare ammonite from the Middle Jurassic of France. Carefully selected for quality and authenticity, it makes an ideal specimen for both collectors and educational display.

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.
