Fossil Type, Species and Scientific Classification

Taramelliceras pseudoflexuosum is an ammonite, an extinct marine cephalopod belonging to the order Ammonitida. Ammonites were related to modern squid, cuttlefish, octopus, and nautilus, and are among the most recognisable fossils of the Jurassic Period. Their coiled shells, chambered internal structure, varied ornamentation, and rapid evolutionary development make them highly valued by collectors and important in palaeontology.

This specimen belongs to the genus Taramelliceras and the species Taramelliceras pseudoflexuosum. Taramelliceras is commonly associated with the family Oppeliidae, a group of Jurassic ammonites often recognised for compressed, elegant shell forms, refined coiling, and detailed surface ornamentation. Oppeliid ammonites are especially appealing to collectors who appreciate finely formed ammonites with strong scientific context and classic Upper Jurassic provenance.

Geological Age and Kimmeridgian Context

This fossil dates from the Kimmeridgian Stage of the Upper Jurassic, approximately 157 to 152 million years ago. The Kimmeridgian was a time of widespread marine environments across Europe, with ammonites forming an abundant and diverse part of ancient sea life. Because ammonites evolved quickly and were widely distributed, many species are useful for comparing and dating Jurassic sedimentary rocks.

During the Kimmeridgian, ammonites such as Taramelliceras pseudoflexuosum lived as active swimming marine animals. Their chambered shells helped regulate buoyancy in the water column, while the living animal occupied the outer body chamber. After death, the shell could settle onto the sea floor, become buried by sediment, and eventually fossilise through mineralisation, compaction, and natural geological alteration.

Le Bignon, Curcy-sur-Orne, Calvados Locality

This specimen comes from Le Bignon, Curcy-sur-Orne, in Calvados, Normandy, France. Normandy is well known for Jurassic sedimentary rocks and fossil-bearing marine deposits, including ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other marine fossils. Specimens from this region are popular with collectors because they represent classic European Jurassic faunas and well-studied geological settings.

During the Upper Jurassic, the Normandy region formed part of a marine environment connected to wider European seas. Carbonate-rich sediments, marls, limestones, and sea-floor deposits helped create conditions in which ammonite shells could become buried and preserved. Over millions of years, these deposits became fossiliferous rock layers, recording the marine life that once inhabited the area.

Ammonite Morphology and Natural Features

Taramelliceras pseudoflexuosum displays the classic planispiral ammonite shell form, with the shell coiled in a flat spiral. The whorls represent successive growth stages as the ammonite matured. Species of Taramelliceras are often admired for their compressed profile, neat whorl shape, refined ornamentation, and balanced spiral form.

The name pseudoflexuosum suggests comparison with flexuous or gently curving ornamentation, and specimens of this group may show fine ribbing, subtle striations, shell curvature, compressed whorls, or an elegant overall outline depending on preservation. The outer shell shape, whorl proportions, ornament pattern, and umbilical structure are important features used in ammonite comparison and identification.

Natural details such as small fractures, sedimentary contact marks, worn areas, colour variation, mineral staining, matrix attachment, and fossilisation texture are part of the specimen’s geological history. These characteristics give the fossil individuality and help distinguish a genuine natural ammonite from a modern cast or replica.

Collecting, Display and Educational Interest

This Taramelliceras pseudoflexuosum ammonite fossil is well suited for display in a fossil cabinet, study, classroom, office, collection drawer, natural history arrangement, or Upper Jurassic fossil collection. Its named species identification, Kimmeridgian age, Normandy origin, and classic ammonite form give it strong collecting appeal.

It is suitable for collectors interested in French fossils, Jurassic ammonites, extinct cephalopods, marine invertebrates, palaeontology, geology, educational fossil specimens, and natural history display pieces. The natural coiled shell form gives the fossil immediate visual impact, while the species name, geological age, and Le Bignon locality provide valuable scientific context for anyone interested in prehistoric marine environments.
