Long Description

Rare Dufrenoyia sinzovi Ammonite Fossil from Vaucluse, France

This listing features a rare Dufrenoyia sinzovi ammonite fossil from the Lower Aptian stage of the Early Cretaceous period, collected in the fossil-rich region of Vaucluse, France. Dating back approximately 125 to 113 million years ago, this ammonite represents an important piece of natural history and a highly desirable addition for collectors. The specimen displayed is the exact fossil you will receive, photographed with a 1 cm scale cube for precise measurement. Every fossil we supply is guaranteed authentic and is accompanied by a Certificate of Authenticity.

Geological Age and Depositional Environment

The Aptian stage of the Early Cretaceous was a dynamic period of Earth’s history marked by high global sea levels, warm marine environments, and the diversification of ammonites. The seas covering what is now southern France provided ideal conditions for the preservation of ammonites like Dufrenoyia sinzovi. Fine-grained marine sediments rapidly buried the shells after death, creating the conditions for exceptional fossilisation.

This fossil not only showcases the biological heritage of the Lower Aptian seas but also serves as a vital geological marker. Ammonites from this time are widely used by geologists as index fossils, enabling precise correlation of rock layers and enhancing our understanding of Early Cretaceous stratigraphy.

Scientific Classification

• Order: Ammonitida
• Superfamily: Acanthocerataceae
• Family: Parahoplitidae
• Genus: Dufrenoyia
• Species: sinzovi

Dufrenoyia sinzovi is an ammonite species highly valued in paleontology for its stratigraphic importance and distinctive morphology.

Morphological Characteristics

The shell of Dufrenoyia sinzovi is distinguished by its moderately evolute coiling, allowing visibility of the inner whorls, and its pronounced ribbing, which strengthens the shell structure and provides an instantly recognisable pattern. The ribs often bifurcate as they progress across the flanks, converging on a strong ventral keel. These features reflect adaptations for life in open marine environments, providing both hydrodynamic efficiency and shell strength.

The suture lines of this species, where the chamber walls meet the outer shell, are complex and deeply lobed, contributing to its visual appeal and scientific identification. The preserved details on this specimen reveal traits that make it a key reference point for both collectors and geologists.

Importance in Stratigraphy and Paleontology

As a Lower Aptian ammonite, Dufrenoyia sinzovi plays a significant role in biostratigraphic studies. Its limited stratigraphic range makes it highly reliable for dating marine sedimentary rocks across Europe and beyond. This precision makes the species one of the most valuable ammonites for scientific research. For collectors, the rarity and significance of this ammonite enhance its desirability and long-term value.

Collectible and Display Value

This rare fossil ammonite from Vaucluse, France, offers both aesthetic and scientific appeal. Its sharp ribbing, pronounced keel, and geological importance combine to create a specimen that is as striking in appearance as it is meaningful in research. Displayed as part of a collection, it represents a tangible link to the Early Cretaceous seas and the evolutionary history of ammonites.

Whether you are a seasoned fossil collector, a student of geology, or someone looking for a unique and authentic natural history specimen, this Dufrenoyia sinzovi ammonite fossil is a truly remarkable piece. With its rich geological background, scientific importance, and guaranteed authenticity, it stands as an exceptional addition to any collection.
