Long Description

Rare Dufrenoyia lurensis Ammonite Fossil from Vaucluse, France

This listing offers a rare and scientifically important Dufrenoyia lurensis ammonite fossil from the Lower Aptian stage of the Early Cretaceous, discovered in the Vaucluse region of France. Dating back around 125–113 million years, this ammonite provides an exceptional glimpse into the marine ecosystems that thrived in the warm, shallow seas of the Cretaceous. The specimen shown in the photographs is the exact piece you will receive, with scale provided by a 1 cm cube for precise measurement. Every fossil is carefully chosen for quality and comes complete with a Certificate of Authenticity.

Geological Context – Lower Aptian Cretaceous

The Aptian stage of the Early Cretaceous was a period of major evolutionary diversification in marine life. The Vaucluse region in southeastern France is world-renowned for its well-preserved Aptian fossil beds, formed in shallow continental seas under warm climatic conditions. Sediments rich in calcareous material created perfect conditions for fossilisation, capturing fine details of ammonite shells and other marine organisms.

The Aptian seas hosted an abundance of ammonites, which not only flourished but also developed distinctive morphologies that today serve as critical biostratigraphic markers for correlating Aptian strata across Europe and beyond.

Species Overview – Dufrenoyia lurensis

Dufrenoyia lurensis is a distinctive member of the Family Parahoplitidae, within the Superfamily Acanthocerataceae and the Order Ammonitida. This ammonite is highly regarded for its unique shell features, making it an important species both for collectors and for paleontological research.

Notable morphological traits include:

• A robust, evolute shell with wide whorls.
• Strongly ribbed ornamentation, often with ribs bifurcating or branching across the flanks.
• A well-defined ventral keel, adding to its characteristic appearance.
• Sutures that are complex and sharply defined, indicative of the evolutionary adaptations of the group.

These features demonstrate that Dufrenoyia lurensis was a nektonic predator, well adapted to active swimming in open marine environments. Like other ammonites, it likely fed on smaller marine invertebrates and plankton.

Scientific Importance

As an ammonite of the Aptian stage, Dufrenoyia lurensis serves as a vital index fossil. Its distinctive shell morphology allows geologists to precisely identify and date the rock layers in which it is found. The species has been described in detail in stratigraphic and paleontological studies of the Aptian, highlighting its role in refining the geological timescale.

Collectors prize this species for its rarity, scientific significance, and striking preservation. Ammonites from Vaucluse are especially valued for their crisp detail and completeness, making them excellent specimens for both academic study and display collections.

Aesthetic and Educational Value

This Dufrenoyia lurensis fossil ammonite offers a perfect combination of scientific and visual appeal. Its bold ribbing and distinctive form make it a natural display piece, while also providing educational value for those interested in Earth’s evolutionary history. Museums, educators, and private collectors alike will appreciate its contribution to understanding the biodiversity of the Early Cretaceous.
