Description

Choffatia cf. kontkiewiczi Ammonite Fossil from Saint-Léon-sur-Vienne, France

This genuine Choffatia cf. kontkiewiczi ammonite fossil comes from Saint-Léon-sur-Vienne, Vienne, France, and dates to the Middle Callovian Stage of the Middle 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 specimen you will receive.

Choffatia ammonites are collectable Jurassic cephalopod fossils, admired for their attractive ribbed shell form, scientific interest and classic Middle Jurassic age. This specimen is especially suitable for collectors of European ammonites, French Jurassic fossils, Callovian marine life and natural history display pieces.

Species and Scientific Interest

Choffatia cf. kontkiewiczi is an extinct ammonite, part of 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 internal chambers helped regulate buoyancy as it moved through the water column.

The “cf.” in Choffatia cf. kontkiewiczi means the specimen compares closely with Choffatia kontkiewiczi, while allowing for careful scientific caution in the exact species-level identification. This is a standard palaeontological notation used when a fossil shows strong similarity to a named species but is best labelled conservatively.

Choffatia is generally placed within the family Perisphinctidae, a major Jurassic ammonite family known for evolute coiling, visible whorls and well-developed ribbing. Perisphinctid ammonites are highly important in Jurassic palaeontology because their shell features and evolutionary changes help geologists date and correlate sedimentary rock layers.

Middle Callovian Jurassic Geology

This fossil dates to the Middle Callovian, part of the Middle Jurassic, approximately 164 million years old. During this time, much of western Europe was covered by warm, shallow epicontinental seas. These marine environments supported a diverse ecosystem that included ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids and marine reptiles.

Sediments deposited on the sea floor preserved many hard-shelled organisms, creating fossil-rich Jurassic strata. Ammonites such as Choffatia are particularly valuable as guide fossils because their shell shapes and ornamentation changed through time. This makes them useful for understanding the age and sequence of Jurassic deposits, as well as being attractive and highly collectable display fossils.

Locality: Saint-Léon-sur-Vienne, Vienne, France

This specimen comes from Saint-Léon-sur-Vienne in the Vienne department of western France, a region known for fossil-bearing Jurassic sedimentary deposits. During the Middle Jurassic, this area formed part of a shallow marine setting where ammonites and other sea life flourished. Over millions of years, the sediments hardened into rock, preserving the remains of ancient marine organisms.

French Jurassic ammonites are popular with collectors due to their variety, scientific importance and often attractive preservation. A labelled specimen from Saint-Léon-sur-Vienne adds excellent locality detail to a fossil collection and is ideal for anyone building a display of European ammonites, Callovian fossils or Middle Jurassic marine specimens.

Morphology and Display Features

Choffatia ammonites typically show a coiled planispiral shell with open, visible whorls and strong ribbed ornamentation. The ribs formed part of the original shell sculpture and may be straight, curved, branching or slightly irregular depending on the growth stage and preservation. These surface details give the fossil its classic ammonite appearance and make it visually appealing as a natural display piece.

Depending on the individual specimen, natural colours may include cream, beige, grey, brown or iron-rich tones, often with contrast between the fossil and any surrounding matrix. Natural variation in colour, texture, rib definition, surface detail and preservation is part of the fossil’s geological character. As the photo shows the actual specimen you will receive, this is a unique fossil rather than a generic stock example.

Authenticity and Collector Appeal

This Choffatia cf. kontkiewiczi ammonite is a genuine Middle Callovian, Middle Jurassic fossil from Saint-Léon-sur-Vienne, Vienne, France. It includes a Certificate of Authenticity lifetime guarantee generic card, giving confidence to fossil collectors, geology enthusiasts, students and gift buyers.

With its carefully labelled scientific identification, French locality, Middle Jurassic age and attractive ribbed ammonite form, this fossil would make an excellent addition to a Jurassic fossil collection, ammonite display, European fossil suite, educational geology collection or natural history cabinet.
