Deshayesites Deshayesi Ammonite Fossil Middle Albian Cretaceous Aube France Certified Specimen

Description

Authentic Deshayesites Deshayesi Ammonite Fossil from France

This listing features a genuine Deshayesites deshayesi ammonite fossil from the Middle Albian stage of the Cretaceous period, discovered in the Aube region of France. This exceptional specimen dates to approximately 110 million years ago, providing a unique opportunity to own a scientifically significant and highly collectable fossil. The fossil comes with a Certificate of Authenticity and the photo provided shows the exact specimen you will receive. A 1 cm scale cube is included in the images for accurate size reference.

Geological Context and Age

The Middle Albian stage belongs to the Early Cretaceous, a time when much of Europe was submerged under shallow epicontinental seas. These seas created perfect conditions for the deposition and fossilisation of ammonites and other marine organisms. The sediments of the Aube region are particularly well known for producing finely preserved ammonite fossils, making them highly sought after by both collectors and researchers. This fossil represents an important link in the evolutionary record of ammonites during this dynamic geological interval.

Scientific Classification

• Class: Cephalopoda
• Subclass: Ammonoidea
• Order: Ammonitida
• Superfamily: Deshayesitoidea
• Family: Deshayesitidae
• Genus: Deshayesites
• Species: Deshayesites deshayesi

Named after the French palaeontologist Gérard Paul Deshayes, Deshayesites deshayesi is a benchmark ammonite species within the Albian, widely used in biostratigraphy as a zonal indicator fossil. Its presence allows geologists to correlate rock layers across Europe and beyond, making it an invaluable tool in understanding Cretaceous stratigraphy.

Morphological Features

This ammonite is characterised by its evolute shell form, with whorls that are only slightly overlapping, leaving earlier whorls visible. The shell exhibits strong, regular ribbing that extends across the flanks and onto the venter. These ribs are a diagnostic feature of Deshayesites deshayesi and are especially valuable for identification. The suture lines are intricate, reflecting the complex internal architecture of the shell that allowed buoyancy control in ancient seas. The aesthetic beauty of these ribbed shells makes them desirable as display pieces, in addition to their scientific importance.

Palaeontological Significance

Deshayesites deshayesi is considered an index fossil for the Albian, meaning its restricted time range makes it highly useful for dating and correlating sedimentary rock layers. Its presence in the Aube region provides important evidence of marine environments in western Europe during the Early Cretaceous. Fossils like this played a key role in reconstructing ancient ecosystems, climate conditions, and evolutionary pathways of marine organisms.

Collectors’ and Display Value

Owning a Deshayesites deshayesi ammonite fossil offers both scientific and aesthetic appeal. Collectors prize these specimens for their rarity, preservation, and importance in palaeontological research. Displayed in a collection, study, or museum setting, this ammonite is a conversation piece that connects its owner directly to the ancient Cretaceous seas of France.

All of our fossils are 100% genuine specimens, carefully chosen for quality and authenticity, and include a Certificate of Authenticity. This Deshayesites deshayesi ammonite is not only a striking natural object but also a scientifically significant fossil that adds depth and prestige to any collection.
