Dated to approximately 163–161 million years ago, this ammonite represents an important chapter in Earth’s geological and palaeontological history. The specimen you see in the photographs is the exact fossil you will receive, and it comes with a Certificate of Authenticity, ensuring its provenance and genuine nature.
Geological Context
The Lower Oxfordian Stage of the Jurassic is a significant interval within the Late Jurassic, marked by the diversification of ammonites, which played a key role as biostratigraphic markers. The deposits around Villiers-sur-Mer in Normandy are well known for their exceptional preservation and yield a wide variety of marine fossils. During this time, the region was covered by warm shallow seas where sedimentation created conditions ideal for fossilisation, leaving behind ammonites such as Cardioceras buckowskii preserved in beautiful detail.
Scientific Classification
- Species: Cardioceras buckowskii
- Genus: Cardioceras
- Family: Cardioceratidae
- Superfamily: Stephanoceratoidea
- Order: Ammonitida
- Class: Cephalopoda
- Age: Lower Oxfordian, Jurassic (~163–161 million years ago)
- Locality: Villiers-sur-Mer, France
Morphological Features
The Cardioceras buckowskii ammonite is characterised by its strongly ribbed and ornamented shell, which displays prominent ribs extending across the flanks and curving towards the venter. This ribbing, coupled with the moderately involute shell structure, gives the species a distinct sculptured appearance. Such features are not only aesthetically striking but also crucial in distinguishing Cardioceras buckowskii from closely related ammonites within the genus.
The clear ribbing patterns and coiling morphology make this ammonite an impressive specimen for display, showcasing the evolutionary adaptations of cephalopods in the Late Jurassic seas. Its preservation offers insight into the fine structural details of ammonite shells, which help palaeontologists study species variation and palaeoecology.
Stratigraphic and Palaeontological Significance
Ammonites of the genus Cardioceras serve as important index fossils for the Oxfordian Stage, allowing geologists to precisely date and correlate Jurassic sediments across Europe. The presence of Cardioceras buckowskii in the Lower Oxfordian biozones is particularly valuable in refining stratigraphic frameworks. Its distribution reflects the expansion of marine habitats during the Jurassic, when rising sea levels and shifting depositional environments promoted biodiversity in ammonite faunas.
Depositional Environment
During the Lower Oxfordian, Villiers-sur-Mer was part of a shallow, warm epicontinental sea. The seabed was composed of fine sediments that buried ammonites and other marine life shortly after death, preserving them for millions of years. Fossils from this region, including this specimen of Cardioceras buckowskii, represent a vibrant ecosystem where ammonites coexisted with bivalves, brachiopods, belemnites, fish, and marine reptiles.
Collector and Display Value
This Cardioceras buckowskii ammonite fossil is both a scientifically valuable specimen and a visually striking piece of natural history. Its well-preserved ribbing and characteristic Jurassic morphology make it highly desirable for fossil collectors, educators, and enthusiasts alike. Whether showcased in a collection, used for teaching, or displayed as a natural history piece, this fossil captures the beauty and history of life in the Jurassic seas.
