Description
Genuine Taramelliceras externnodosum Ammonite Fossil
This listing is for a genuine Taramelliceras externnodosum ammonite fossil from the Malm, Upper Jurassic, Lower Kimmeridgian Stage, collected from Gößweinstein, Bavaria, Germany. This carefully chosen fossil is a desirable Jurassic marine specimen, ideal for collectors of ammonites, German fossils, fossil cephalopods, natural history pieces, educational geology specimens, and prehistoric marine life displays.
The photograph shows the actual fossil specimen you will receive, so the shape, preservation, colour, surface detail, and natural character shown in the image belong to this exact piece. For full sizing and scale, please see the photo.
Fossil Type and Species Information
This fossil is an ammonite, an extinct marine cephalopod related to modern squid, cuttlefish, octopus, and nautilus. Ammonites lived in ancient seas and are among the most collectable fossils from the Jurassic Period due to their coiled shells, varied ornamentation, scientific importance, and strong visual appeal.
The species is Taramelliceras externnodosum, an Upper Jurassic ammonite associated with European marine deposits. The genus Taramelliceras is generally known for ornate ammonites with compressed, planispiral shells and decorative surface features. The species name externnodosum suggests the presence of external nodes or raised ornamentation along part of the shell, a feature that can make specimens especially attractive to collectors. Depending on preservation, examples may show whorl shape, ribbing, nodose ornament, shell relief, and natural mineralised texture.
Ammonites had chambered shells divided internally into compartments. The living animal occupied the outer body chamber, while the inner chambers helped with buoyancy control. These animals were successful marine predators or active swimmers in Jurassic seas, and their fossilised shells remain one of the best-known links to prehistoric ocean life.
Upper Jurassic Lower Kimmeridgian Age
This specimen dates from the Upper Jurassic Period, specifically the Lower Kimmeridgian, making it approximately 157 to 155 million years old. The Kimmeridgian was an important interval in Late Jurassic marine history, when ammonites were widespread and highly diverse across the warm epicontinental seas that covered much of Europe.
During this time, the region now known as Bavaria lay within a marine environment where carbonate-rich sediments, muds, and limestones accumulated over time. These seas supported ammonites, belemnites, bivalves, brachiopods, crinoids, sponges, corals, fish, and marine reptiles. After death, ammonite shells could settle on the sea floor, become buried by sediment, and gradually fossilise through mineral replacement and compaction over millions of years.
Malm Geology of Bavaria
This fossil comes from the Malm, the traditional German term for Upper Jurassic rock sequences. The Malm deposits of southern Germany are famous for their marine limestones and fossil-bearing strata, especially ammonites and other sea life from the Late Jurassic. These rocks preserve evidence of ancient warm seas that once covered large parts of central Europe.
Bavarian Jurassic fossils are especially popular with collectors because of their classic European locality data, attractive preservation, and long history of palaeontological study. The combination of species identification, geological age, and locality makes this fossil a strong display and reference specimen.
Gößweinstein, Bavaria, Germany Locality
This Taramelliceras externnodosum ammonite was collected from Gößweinstein, Bavaria, Germany, a region associated with Jurassic limestone landscapes and fossiliferous marine deposits. Fossils from this area help represent the rich ammonite faunas that lived in the Late Jurassic seas of southern Germany.
A fossil with clear locality information is more desirable than an unlabelled decorative ammonite, as it can be properly catalogued, displayed, and appreciated within a scientific or collector context. This makes the specimen suitable for both experienced collectors and those building a labelled natural history collection.
Natural Collector Display Specimen
This genuine ammonite fossil would display well in a fossil cabinet, geology collection, educational set, curiosity cabinet, or prehistoric marine life display. It is suitable for collectors of Jurassic fossils, Lower Kimmeridgian fossils, German ammonites, fossil cephalopods, Malm fossils, and scientifically labelled display specimens.
As with all genuine fossils, the piece may show natural characteristics such as matrix, mineral staining, surface texture, small cracks, weathering, repaired areas, or variations in preservation. These features are part of the fossil’s geological history and help demonstrate its authenticity as a real prehistoric specimen.
Certificate of Authenticity Included
This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. This provides reassurance that the fossil supplied is authentic and suitable for collecting, study, gifting, display, resale, or educational use.
