RARE: Kamerunoceras turoniense Fossil Ammonite – Turonian, Cretaceous – Bourges, France | Authentic Ammonite Fossil | COA Included
£ 18.00
This listing features a RARE fossil ammonite specimen of Kamerunoceras
turoniense, beautifully preserved and discovered in Bourges, France, from the Turonian stage of the Late Cretaceous. This genus is a key representative of mid-Cretaceous ammonite faunas and holds high value for collectors and palaeontologists alike.As always, this is a 100% genuine fossil, and the exact specimen shown in the photographs is the one you will receive. The fossil is carefully selected for quality and is accompanied by a Certificate of Authenticity. For full sizing, please refer to the photo with the 1cm scale cube. FOSSIL OVERVIEW:
• Species: Kamerunoceras turoniense
• Common Name: Fossil Ammonite
• Geological Period: Cretaceous
• Stage: Turonian (~93.9 to 89.8 million years ago)
• Locality: Bourges, Centre-Val de Loire, France
• Preservation: External mould with some shell detail in natural matrix GEOLOGICAL CONTEXT & DEPOSITIONAL ENVIRONMENT:This fossil originates from marine sediments laid down during the Turonian, a time when Europe was submerged beneath a warm, shallow inland sea. The area around Bourges represents part of a carbonate platform that preserved a diverse array of marine organisms.The depositional environment was likely a low-energy offshore shelf, rich in plankton and other marine life that supported nektonic ammonites such as Kamerunoceras. These open-marine sediments, typically chalky or marly limestones, provided ideal conditions for fossilisation. BIOZONE SIGNIFICANCE:Kamerunoceras turoniense is indicative of the Upper Turonian ammonite zones, potentially within the Collignoniceras woollgari or Subprionocyclus neptuni zones, depending on locality. These biozones are used for high-resolution correlation of Turonian strata across Western Europe and North Africa. TAXONOMY & CLASSIFICATION:
• Phylum: Mollusca
• Class: Cephalopoda
• Subclass: Ammonoidea
• Order: Ammonitida
• Superfamily: Acanthoceratoidea
• Family: Acanthoceratidae
• Genus: Kamerunoceras
• Species: turoniense MORPHOLOGICAL FEATURES:Kamerunoceras is characterised by:
• Strong ribbing across the whorls
• Presence of prominent tubercles or nodes along the ventrolateral margins
• Moderately evolute coiling with exposed inner whorls
• A compressed, somewhat involute shell profile
• A wide ventral area that may show weak keel developmentThese features reflect a nektonic (actively swimming) lifestyle, typical of mid-Cretaceous ammonites. NOTABLE INFORMATION:
• Kamerunoceras is an important Turonian index fossil
• Shows global distribution from Europe to Africa and parts of the Americas
• Fossils of this genus are relatively scarce in the commercial market
• Ideal for collectors seeking rare ammonites from the mid-Cretaceous
• Scientifically valuable for correlation and palaeobiogeographyWhy Buy From Us?
