Maconiceras vigoense Ammonite Fossil from Aveyron, Occitanie, France

This genuine Maconiceras vigoense ammonite fossil comes from Aveyron, Occitanie, France, and dates to the Toarcian Stage of the Lower Jurassic. It is a carefully chosen fossil specimen, supplied with a Certificate of Authenticity lifetime guarantee generic card. Full sizing can be seen in the photo, and the image shows the actual fossil specimen you will receive.

Maconiceras vigoense is a collectable Lower Jurassic ammonite, valued for its scientific interest, named species identification, French locality and classic coiled cephalopod form. Specimens from Aveyron are especially appealing to collectors of European ammonites, French Jurassic fossils, Toarcian marine life, fossil cephalopods and natural history display pieces.

Species and Scientific Interest

Maconiceras vigoense is an extinct ammonite species belonging to the ammonoid cephalopods, a group of marine molluscs related to modern squid, cuttlefish and nautilus. Ammonites lived in ancient seas and produced coiled, chambered shells. The living animal occupied the outer body chamber, while the earlier chambers helped regulate buoyancy as it moved through the water column.

Maconiceras is associated with Lower Jurassic Toarcian ammonite faunas and represents part of the diverse cephalopod life that flourished in European seas during this time. Ammonites are especially important fossils because many groups evolved rapidly and were widely distributed, making them useful for dating and correlating Jurassic rock layers.

The species name vigoense gives this specimen added collecting value, as named ammonites are often preferred by collectors building scientifically labelled fossil displays. A clearly identified Maconiceras vigoense from Aveyron is an excellent example of a Lower Jurassic ammonite with both display appeal and palaeontological interest.

Lower Jurassic Toarcian Geology

This fossil dates to the Toarcian Stage of the Lower Jurassic, approximately 174 to 183 million years old. During the Toarcian, much of western Europe was covered by marine environments ranging from shallow shelf seas to deeper offshore settings. These seas supported a varied ecosystem that included ammonites, belemnites, bivalves, brachiopods, gastropods, fish and marine reptiles.

The Toarcian is an important interval in Jurassic geology, known for widespread marine sedimentation and significant environmental changes. Depending on locality, Toarcian deposits may include marls, limestones, clays and organic-rich shales laid down across ancient sea floors. These sediments preserved the shells of ammonites and other marine organisms, creating fossil-rich strata now studied and collected across Europe.

Ammonites such as Maconiceras vigoense are valuable for biostratigraphy because their shell forms can help identify relative ages within the rock sequence. This gives the fossil scientific and educational value, as well as making it an attractive natural specimen for display.

Locality: Aveyron, Occitanie, France

This specimen comes from Aveyron in the Occitanie region of southern France, an area known for fossil-bearing Jurassic sedimentary rocks. During the Lower Jurassic, this region formed part of a marine setting connected to wider European seas. Sediments deposited in these ancient waters later hardened into fossiliferous strata, preserving evidence of the animals that lived there millions of years ago.

French Jurassic ammonites are highly collectable because of their variety, geological importance and often attractive preservation. A labelled fossil from Aveyron adds valuable locality information to a collection and is ideal for anyone building a display of French fossils, Lower Jurassic ammonites, Toarcian specimens or European natural history material.

Morphology and Display Features

Maconiceras vigoense displays the classic coiled planispiral shell form associated with ammonites. Depending on preservation, the fossil may show visible whorls, ribbing, growth lines, natural shell texture and surface detail. These features formed part of the original shell structure and are important for both identification and visual appeal.

Natural colours may include cream, beige, grey, brown or iron-rich tones, influenced by the sediment and mineral conditions present during fossilisation. Variations in matrix, rib definition, shell detail, surface texture and preservation are part of the fossil’s authentic geological character. As the photo shows the actual fossil you will receive, this is an individual specimen rather than a generic stock example.

Authenticity and Collector Appeal

This Maconiceras vigoense ammonite is a genuine Toarcian Lower Jurassic fossil from Aveyron, Occitanie, France. It includes a Certificate of Authenticity lifetime guarantee generic card, giving confidence to fossil collectors, geology enthusiasts, students and gift buyers.

With its named species, French locality, Lower Jurassic age and classic ammonite form, this fossil would make an excellent addition to a Jurassic fossil collection, European ammonite display, educational geology cabinet, natural history collection or specialist fossil cephalopod suite.
