Calycoceras naviculare Fossil Chalk Ammonite, Cenomanian, Cretaceous: South West France – 100% Genuine with Certificate of Authenticity
£ 36.00
This Calycoceras naviculare fossil ammonite is a superb specimen from the
Cenomanian Stage of the Cretaceous Period, discovered in South West France. Calycoceras naviculare is an ammonite species known for its distinctive, ribbed shell and prominent suture lines, providing valuable insights into marine life during the Cretaceous. The fossil is beautifully preserved in chalk, which is a well-known medium for preserving marine life from this time period. The specimen is a fine example of an ancient ammonite that once thrived in the shallow seas of the Cretaceous period. GEOLOGICAL INFORMATION:
• Geological Stage: Cenomanian, Cretaceous (Approximately 100.5 to 93.9 million years ago)
• Depositional Environment: During the Cenomanian, shallow marine seas covered much of what is now South West France, providing an ideal environment for ammonites like Calycoceras naviculare to thrive. The chalk deposits in the region were formed from the accumulation of marine life and their remains, which have since been preserved as fossils. The Cenomanian period was marked by the flourishing of marine life, and the Calycoceras naviculare is a classic example of Cretaceous ammonites that lived in these waters.
• Biozone: This fossil comes from the Cenomanian biozone, a period characterized by an abundant diversity of marine organisms including ammonites, bivalves, and other invertebrates that inhabited the warm, shallow seas. The Cenomanian biozone is known for its marine life, which included the early forms of the ammonite family. FOSSIL FEATURES:
• Family: Ammonitidae
• Super Family: Ammonoidea
• Order: Ammonitida
• Morphology: The Calycoceras naviculare ammonite features a distinctively ribbed, coiled shell with prominent ribs that run along the whorls. The shell has a smooth and rounded outer surface with clearly visible suture lines, making it an excellent representation of the Cretaceous ammonite species. The ammonite's whorls are closely coiled, with the shell expanding outward as it grows, creating a visually striking spiraled pattern. The ribbing gives the fossil a textured appearance, enhancing its fossilized beauty. NOTABLE DETAILS:
• This fossil is 100% GENUINE and comes with a Certificate of Authenticity, ensuring its authenticity and historical value.
• The specimen has been carefully selected for its high-quality preservation. The photograph provided shows the actual specimen you will receive, ensuring full transparency in your purchase.
• Scale Rule: The scale rule squares/cube shown in the photo represents 1cm, allowing you to accurately gauge the size of the fossil. Full sizing details are available in the photograph.Condition:This Calycoceras naviculare Fossil Ammonite is in excellent condition, showcasing its distinctive ribbing, well-preserved suture lines, and spiraled shell. The fossil has been cleaned and treated for display, making it an ideal addition to any Cretaceous ammonite collection or for those interested in the marine life of the Cenomanian period.
