Arieticeras africense Ammonite Fossil France Jurassic with COA

Description

Arieticeras africense Ammonite Fossil

A Genuine Lower Jurassic Fossil from Aveyron

This authentic ammonite fossil is identified as Arieticeras africense and comes from Saint-Paul-des-Fonts in Aveyron, Occitanie, southern France. It dates to the Toarcian stage of the Lower Jurassic, placing it within a marine ecosystem around 180 million years old. The photographs show the exact specimen offered for sale, allowing its natural shell form, ribbing, matrix and individual preservation to be examined before purchase. Full dimensions are shown in the dedicated sizing photograph.

Toarcian Age and Marine Environment

The Toarcian was the final stage of the Early Jurassic, spanning approximately 182.7 to 174.1 million years ago. During this interval, large areas of Europe were covered by warm, relatively shallow seas connected to the Tethys Ocean. Sediment accumulated across continental shelves and deeper basins, preserving the remains of abundant marine organisms. Ammonites were among the most diverse and useful fossils formed in these environments.

The Toarcian is of particular interest to geologists because its rock record captures major environmental changes as well as the evolution and turnover of marine faunas. Fossils with a known regional and stratigraphic provenance help connect individual specimens with this broader history. This Arieticeras africense therefore represents both an attractive natural object and a genuine record of an ancient Jurassic sea.

Saint-Paul-des-Fonts and Aveyron Geology

Saint-Paul-des-Fonts lies in the Aveyron department of Occitanie, a region known for extensive sedimentary rocks and fossiliferous Jurassic exposures. The limestone and marl sequences of southern France have yielded important ammonite assemblages used to study and correlate Early Jurassic strata. Retaining the locality information with the specimen preserves a meaningful part of its scientific context and distinguishes it from an ammonite with no recorded origin.

About Arieticeras africense

Arieticeras is a genus of Early Jurassic ammonites recognised from features of its coiled shell, whorl shape, ornament and suture pattern. Arieticeras africense belongs to the diverse ammonite communities that inhabited Toarcian seas. As the animal grew, it added new shell material at the aperture, increasing the size of the spiral while leaving older chambered portions behind. Visible ribs and other surviving surface details record aspects of that growth.

Ammonites were extinct marine cephalopods related to living squid, cuttlefish and nautiluses. The animal occupied the outer body chamber, while the older shell was divided internally by septa. Those sealed chambers played a role in buoyancy control, helping the ammonite move through the water. The intricate lines formed where septa met the outer shell, called sutures, are important features in ammonite identification and classification.

Because ammonites evolved rapidly and were distributed across broad marine regions, palaeontologists use them to compare and date sedimentary rock units. A named specimen such as this Arieticeras africense has value as evidence of both cephalopod evolution and the geological age of the rocks in which it was preserved.

Natural Preservation

This fossil has undergone burial, mineralisation, compaction, erosion and eventual discovery. Natural matrix, mineral colour, weathering, fine cracks, minor losses or irregular surfaces may be present. These features are part of its geological history and are not modern manufacturing defects. Please inspect every image carefully, as the photographs provide the clearest guide to this individual fossil’s condition. The specimen pictured is the exact ammonite you will receive, and no substitute will be supplied.

Collecting, Study and Display

This French Toarcian ammonite is suitable for a fossil collection, geology cabinet, palaeontology display or educational study set. Its species identification and precise Saint-Paul-des-Fonts provenance make it particularly relevant to collectors interested in European ammonites, Lower Jurassic fossils, French geology or ancient marine cephalopods. It can also make a thoughtful gift for a fossil enthusiast, geology student or natural-history collector.

Certificate and Authenticity

This is a carefully selected genuine fossil specimen. It includes a generic Certificate of Authenticity card carrying a lifetime guarantee of authenticity. Its documented provenance is Toarcian, Lower Jurassic, Saint-Paul-des-Fonts, Aveyron, Occitanie, France. Keeping these details with the fossil will preserve its scientific and historical value. The listing photographs show the actual Arieticeras africense offered here, and the sizing image provides the measurements needed for storage or display planning.
