Rare Dichotomoceras Fossil Ammonite | Lower Oxfordian Jurassic | Vienne France | Genuine Specimen with COA

£36.00

This listing is for a Rare Fossil Ammonite (Dichotomoceras sp.) from the Lower Oxfordian Stage of the Late Jurassic, discovered in Vienne, 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).
  • Genus: Dichotomoceras.
  • Order: Ammonitida.
  • Superfamily: Perisphinctoidea.
  • Family: Perisphinctidae.
  • Geological Period: Jurassic.
  • Stage/Age: Lower Oxfordian (approx. 163 – 161 million years ago).
  • Locality: Vienne, France.

 

Notable Features & Morphology:

  • Shell Form: Evolute with open coiling, showing visible inner whorls.
  • Ribs: Strong, bifurcating ribs crossing the flanks, diagnostic of Dichotomoceras.
  • Whorl Section: Rounded to slightly compressed, creating an ornate ribbed appearance.
  • Size: A rare, well-preserved specimen from the Oxfordian, ideal for display.

 

Depositional Environment:

During the Oxfordian, the Vienne region of France was part of shallow epicontinental seas rich in carbonate sediments. These marine environments preserved ammonites in limestone and marl, ensuring fine fossil detail.

 

Scientific & Collecting Importance:

Dichotomoceras species are important ammonites for biostratigraphic correlation within the Oxfordian. Their distinctive bifurcating ribbing and shell form make them highly recognisable index fossils and prized specimens for collectors.

 

Why Buy This Fossil?

  • A rare ammonite specimen from the Lower Oxfordian of Vienne, France.
  • Excellent preservation with characteristic bifurcating ribs.
  • A valuable 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.
