RARE Dichotomoceras stenocycloides Fossil Ammonite – Oxfordian Stage – Jurassic – France – Genuine Specimen with Certificate
£14.40
This listing is for a RARE fossil ammonite specimen of Dichotomoceras stenocycloides from the Oxfordian stage of the Jurassic period, discovered in France. A highly collectible ammonite, this species displays striking evolutionary features characteristic of its time and location.
Fossil Type: Ammonite (extinct marine cephalopod)
Species: Dichotomoceras stenocycloides
Geological Period: Jurassic
Geological Stage: Oxfordian (~163 to 157 million years ago)
Provenance: France
Formation: Likely from marine calcareous deposits typical of the Oxfordian strata in western Europe
Scientific and Geological Details:
Order: Ammonitida
Superfamily: Perisphinctoidea
Family: Aspidoceratidae
Morphology Features:
Strongly ribbed evolute shell with characteristic branching ribs
Whorls display narrow, compressed cross-section
Ornamentation helps distinguish it from other closely related genera
Depositional Environment:
Open marine setting in the tropical-subtropical Tethys Ocean belt
Deposits formed in relatively shallow carbonate-rich seafloors
Biozone:
Falls within the Perisphinctes–Dichotomoceras ammonite biozones of the Upper Oxfordian
Notable:
The genus Dichotomoceras is notable for its complex suture lines and as a key faunal indicator in Upper Jurassic stratigraphy
Species-level identification (D. stenocycloides) has been used in European biostratigraphy
Formally Described By: Arkell, W.J., an authority on Jurassic ammonites
Why This Fossil Is Special:
Rare and scientifically significant genus and species
Excellent preservation of ornamental and structural features
A prime example of ammonite morphology from the Oxfordian
Ideal for display, educational purposes, or paleontological collections
Collected from a classic French Jurassic locality with stratigraphic importance
Additional Information:
All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity
Scale Rule Squares / Cube = 1cm: Full sizing please see photo
You will receive the exact fossil shown in the listing – carefully selected for quality and scientific value

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.
