This listing features a RARE and striking 8-inch Fossil Ammonite – Morrisiceras
sphaera, a beautifully preserved example from the Middle Bathonian Stage of the Jurassic Period, collected from Davage, France. This large and robust ammonite is a prized addition for collectors of Jurassic marine life.As with all our items, this is a 100% genuine fossil, carefully selected and professionally curated. It comes with a Certificate of Authenticity. The specimen shown in the photos is the exact item you will receive. Please refer to the scale cube photo (1cm squares) for full sizing.FOSSIL OVERVIEW:
• Species: Morrisiceras sphaera (d’Orbigny, 1845)
• Type: Fossil Ammonite
• Geological Period: Jurassic
• Stage: Middle Bathonian (~168–166 million years ago)
• Biozone (likely): Morrisiceras Zone (within the Zigzag or Retrocostatum Subzones)
• Location: Davage, France
• Specimen Size: Approx. 8 inches (20 cm)
• Preservation: Natural fossil in matrix (likely limestone or marl)GEOLOGICAL & DEPOSITIONAL CONTEXT:The Middle Bathonian of France is well known for its richly fossiliferous marine strata, deposited in a shallow epicontinental sea during a warm interval of the Jurassic. These sediments consist mostly of calcareous mudstones and limestones, ideal for preserving hard-shelled marine organisms such as ammonites, brachiopods, bivalves, and belemnites.The ammonite Morrisiceras sphaera is a biostratigraphically significant species, often used to define subzones within the Bathonian Stage. The Davage locality is especially noted for its well-preserved and often large ammonite fossils.TAXONOMY & CLASSIFICATION:
• Phylum: Mollusca
• Class: Cephalopoda
• Order: Ammonitida
• Superfamily: Stephanoceratoidea
• Family: Morphoceratidae
• Genus: Morrisiceras
• Species: M. sphaera (formally described by Alcide d’Orbigny, 1845)MORPHOLOGICAL FEATURES:Morrisiceras sphaera is characterised by:
• A large, globular (sphaerical) coiled shell
• Strong, rounded ribbing that may bifurcate along the flanks
• Deep umbilicus and pronounced ventral keel in some specimens
• Thick shell wall and solid internal preservationThese robust ammonites were nektonic, fast-moving swimmers inhabiting open marine environments, preying on smaller invertebrates.NOTABLE ASPECTS:
• Rare large specimen measuring 8 inches across
• Excellent preservation from a well-known French Bathonian site
• Species named and described by A. d’Orbigny, one of the founding figures of palaeontology
• Important biostratigraphic index fossil for Jurassic correlation across Europe
