Fossil Type, Species and Scientific Classification
Taramelliceras rigidum 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 fossil collectors and important in palaeontology.
This specimen belongs to the genus Taramelliceras and the species Taramelliceras rigidum. Taramelliceras is commonly associated with the family Oppeliidae, a Jurassic ammonite group often recognised for compressed shell forms, refined coiling, neat whorl proportions, and detailed surface ornamentation. Oppeliid ammonites are especially appealing to collectors who appreciate finely shaped ammonites with strong scientific context and classic Upper Jurassic provenance.
Geological Age and Lower Kimmeridgian Context
This fossil dates from the Lower Kimmeridgian, the early part of the Kimmeridgian Stage within the Upper Jurassic. The Kimmeridgian occurred approximately 157 to 152 million years ago and was a time of widespread marine environments across Europe. Ammonites were abundant and diverse during this interval, making them valuable fossils for comparing and dating Jurassic sedimentary rocks.
During the Lower Kimmeridgian, ammonites such as Taramelliceras rigidum lived as active swimming marine animals. Their shells were divided into internal chambers, with the living animal occupying the outer body chamber. This chambered shell helped regulate buoyancy in the water column, allowing ammonites to move through Jurassic seas before their shells eventually settled onto the sea floor after death.
Böttingen bei Spaichingen, Baden-Württemberg Locality
This specimen comes from Böttingen bei Spaichingen in Baden-Württemberg, Germany, a region known for important Jurassic sedimentary rocks and fossil-bearing marine deposits. German Jurassic ammonites are highly collectable because they often come from classic European geological settings with strong scientific context, attractive preservation, and precise locality information.
During the Upper Jurassic, parts of what is now southern Germany were covered by marine environments connected to broader European seas. Carbonate-rich sediments, limestones, marls, and sea-floor deposits helped preserve the remains of ancient marine organisms. These environments supported ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other marine invertebrates. Over millions of years, mineralisation, compaction, and natural geological alteration preserved some shells as fossils within the sedimentary rock record.
Ammonite Morphology and Natural Features
Taramelliceras rigidum 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, balanced spiral outline, narrow to moderate umbilicus, and refined surface features.
The species name rigidum suggests a firm or strongly defined shell character, and specimens of this type may show a neat whorl outline, controlled coiling, fine ribbing or striation, shell curvature, natural mineral staining, matrix attachment, surface wear, or fossilisation texture. 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 deposits, and matrix are part of the fossil’s geological history. These characteristics add individuality to the specimen and help distinguish a genuine natural fossil from a modern cast or replica.
Collecting, Display and Educational Interest
This Taramelliceras rigidum 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, Lower Kimmeridgian age, German origin, and classic ammonite form give it strong collecting appeal.
It is suitable for collectors interested in German 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 Baden-Württemberg locality provide valuable scientific context for anyone interested in prehistoric marine environments.
