Description

Genuine Parawedekindia arduennensis Ammonite Fossil

This listing is for a genuine Parawedekindia arduennensis ammonite fossil from the Upper Jurassic, Lower Oxfordian Stage, collected from Les Vieux, France. This carefully chosen fossil specimen is an excellent piece for collectors of Jurassic ammonites, French fossils, fossil cephalopods, natural history specimens, prehistoric marine life, and educational geology displays.

The photograph shows the actual fossil specimen you will receive, so the colour, shape, preservation, surface texture, and individual character shown in the image belong to this exact fossil. For full sizing and scale, please see the photo.

Fossil Type and Species Information

This fossil is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, octopus, and nautilus. Ammonites are among the most famous and collectable fossils from the Jurassic Period, recognised for their coiled shells, chambered internal structure, varied ornamentation, and importance in dating ancient marine rock layers.

The species is Parawedekindia arduennensis, an Upper Jurassic ammonite associated with Lower Oxfordian marine deposits of Europe. As an ammonite, this specimen represents the fossilised shell of a marine animal that lived in ancient seas over 160 million years ago. The living animal occupied the outer body chamber, while the earlier chambers were used for buoyancy control, allowing the ammonite to move through the water column.

Depending on preservation, specimens of this type may show planispiral coiling, whorl development, ribbing, shell sculpture, natural mineralisation, and surface texture. These features make ammonites highly valued as both attractive display fossils and scientifically interesting specimens. The shell form records the growth of the animal during life, preserving a direct link to the marine ecosystems of the Jurassic Period.

Upper Jurassic Lower Oxfordian Age

This ammonite dates from the Upper Jurassic Period, specifically the Lower Oxfordian, approximately 163 to 160 million years old. The Oxfordian was an important stage in Jurassic marine history, marked by diverse ammonite faunas across Europe and other ancient sea regions.

During the Lower Oxfordian, much of what is now France was influenced by shallow to moderately deep marine environments. These warm Jurassic seas supported ammonites, belemnites, bivalves, brachiopods, gastropods, crinoids, sponges, corals, fish, and marine reptiles. Ammonites were especially successful during this time, evolving into many forms and becoming useful fossils for identifying and correlating rock layers.

After death, ammonite shells could sink to the sea floor and become covered by fine sediment. Over millions of years, mineralisation, compaction, and geological pressure transformed the shell into a fossil, preserving the form of an animal that once lived in the ancient oceans.

Les Vieux, France Geological Locality

This specimen comes from Les Vieux, France, a locality associated with Jurassic fossil-bearing deposits. French Jurassic ammonites are popular with collectors because they combine classic European locality data, strong geological interest, and natural display appeal. Fossils from France help represent the rich marine life that lived across western Europe during the Late Jurassic.

The locality information adds important collector value. A fossil with species, geological stage, age, and place of origin can be properly labelled, catalogued, and displayed as part of a serious fossil collection. This makes the specimen more informative and desirable than an unlabelled decorative ammonite.

Natural Collector Display Specimen

This Parawedekindia arduennensis ammonite fossil is suitable for fossil collectors, geology students, teachers, natural history enthusiasts, and anyone interested in prehistoric marine life. It would display well in a fossil cabinet, educational teaching set, curiosity cabinet, study collection, or natural history-themed display.

As a genuine natural fossil, the specimen may show normal features such as matrix, mineral staining, surface texture, small cracks, weathering, repaired areas, or variations in preservation. These characteristics are typical of authentic fossils and form part of the specimen’s geological history and natural character.

Certificate of Authenticity Included

This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. This provides reassurance that the fossil supplied is authentic and suitable for collecting, study, gifting, display, resale, or educational use.
