Eoderoceras Ammonite Fossil Jurassic France Genuine COA Card Collector Specimen - Bajocian Marine Cephalopod Natural History Display
£ 10.20
Eoderoceras sp. Ammonite Fossil from FranceThis is a genuine Eoderoceras sp. ammonite fossil from the Jurassic of France,
listed as Bajocian in age. This carefully chosen fossil is a desirable marine cephalopod specimen, selected for its natural character, scientific interest, and display appeal. It is supplied with a Certificate of Authenticity lifetime guarantee generic card, making it a trusted addition to a fossil collection, natural history cabinet, geology display, educational collection, or prehistoric gift selection.The photograph shows the actual fossil specimen you will receive. Full sizing and scale can be seen in the photo.Geological Age and LocationThis ammonite comes from the Jurassic Period, a major interval of the Mesozoic Era when ammonites flourished in seas across Europe and the wider world. The specimen is recorded as Bajocian, a stage of the Jurassic associated with highly diverse ammonite faunas and rich marine sedimentary deposits. The Bajocian seas supported a wide range of shelled and soft-bodied marine life, including ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, fish, and marine reptiles.France is particularly important for Jurassic fossils, with many classic fossil-bearing regions preserving marine sediments from ancient European seas. During the Jurassic, large parts of what is now France were covered by warm shallow to moderately deep marine environments connected to the ancient Tethys Ocean and neighbouring seaways. These conditions allowed ammonites to thrive and later become preserved in limestone, marl, clay, and other sedimentary rocks.Fossil Type and IdentificationThis fossil is identified as Eoderoceras sp., an extinct ammonite. The “sp.” designation means the specimen has been identified to genus level, while the exact species is left open. This is a common and scientifically appropriate way to describe fossil ammonites when preservation, natural wear, or visible diagnostic features do not allow a confident species-level assignment.Ammonites were extinct marine molluscs related to modern squid, cuttlefish, octopus, and nautilus. They had coiled, chambered shells, with the living animal occupying the outer body chamber. The internal chambers helped regulate buoyancy, allowing the ammonite to move through the water column. Their shells were divided by internal walls called septa, and the junctions between these septa and the outer shell formed suture patterns that are often important in ammonite classification.Morphology and Notable FeaturesEoderoceras ammonites are valued by collectors for their classic coiled form and strong Jurassic character. Typical features associated with the genus include a planispiral shell, visible whorls, and ornamentation that can include ribbing and raised features depending on preservation and growth stage. Many related ammonites show an evolute shell form, meaning the earlier whorls remain visible around the centre, creating the attractive open spiral appearance collectors often look for in ammonite fossils.The natural shell shape records the growth of the animal over time, with each whorl representing a later stage in its development. Surface texture, ribbing, matrix, mineral tones, and any natural wear all add to the individuality of the specimen. As with all genuine fossils, small chips, cracks, areas of loss, mineral staining, or weathered surfaces may be present as part of the fossil’s geological history. These natural features are part of the authenticity and character of a real prehistoric specimen.Jurassic Marine EnvironmentThis Eoderoceras ammonite lived in an ancient Jurassic sea, long before the modern landscape of France existed. These marine environments were home to a rich ecosystem of cephalopods, shellfish, fish, and other marine organisms. Ammonites were active swimming or drifting animals and are generally thought to have fed on small prey in the water column using tentacles.After death, the ammonite shell settled onto the sea floor, where it could become buried in sediment. Over millions of years, mineralisation and compaction transformed the shell and surrounding sediment into fossil-bearing rock. Fossils like this provide a direct connection to the marine world of the Jurassic, a time when dinosaurs lived on land while ammonites were among the most successful animals in the seas.Authenticity and CollectabilityThis Eoderoceras sp. ammonite fossil is a genuine specimen from France and includes a Certificate of Authenticity lifetime guarantee generic card. It is suitable for collectors of ammonites, Jurassic fossils, French fossils, marine cephalopods, natural history specimens, educational geology pieces, and display fossils.The fossil shown in the photo is the actual specimen you will receive.
