Mesogaudryceras leptonema Fossil Ammonite | Rare Lower Cenomanian Cretaceous | Italy | Genuine Certified Specimen
£ 60.00
A rare and scientifically valuable specimen of Mesogaudryceras leptonema, an
extinct genus of ammonite from the Lower Cenomanian Stage of the Cretaceous Period, discovered in fossil-rich deposits of Italy.Mesogaudryceras leptonema is known for its finely ribbed, evolute shell and detailed suture lines. This genus represents a transitional form between early and more derived ammonite forms of the mid-Cretaceous, making it an important species for biostratigraphic and evolutionary studies.All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.The photo shows the actual specimen you will receive, alongside a 1cm scale cube for precise sizing. Please refer to the image for full measurement details. Geological and Taxonomic Information:
• Species: Mesogaudryceras leptonema
• Fossil Type: Ammonite (extinct marine cephalopod)
• Age: Early Late Cretaceous, Lower Cenomanian (~100.5 to 98 million years ago)
• Location: Italy
• Formation: Marine limestone and marl of the Cenomanian deposits
• Depositional Environment: Open marine shelf with calcareous sedimentation
• Geological Stage: Lower Cenomanian Taxonomic Classification:
• Order: Ammonitida
• Superfamily: Acanthoceratoidea
• Family: Gaudryceratidae
• Genus: Mesogaudryceras Morphology & Notable Features:
• Evolute shell with visible whorls and fine, dense ribbing
• Deeply incised suture lines
• Sub-rounded cross-section with minimal keel
• Excellent preservation and fossil surface detail Scientific & Collector Significance:Mesogaudryceras species are vital for understanding ammonite evolution in the early Late Cretaceous and act as markers in global stratigraphy. This specimen offers a glimpse into marine life during a major greenhouse phase in Earth's history. Specimen Details:
• Approximate Size: Refer to image with 1cm scale cube
• Condition: Expertly cleaned and preserved
• Origin: Italy
• Includes: Certificate of Authenticity Ideal For:
• Collectors of rare European ammonites
• Academic and educational display
• Fossil enthusiasts and palaeontology researchers
• Natural history exhibits and décor
