This Calycoceras (Newboldiceras) tunetanum chalk ammonite fossil from Glynde, United Kingdom, is a beautiful and rare example of Cretaceous marine life. Dating back to the Cenomanian of the Cretaceous period, it hails from an era when much of the planet was covered in shallow seas. The Calycoceras genus is part of the larger Newboldiceras family and is known for its distinct, tightly coiled shells and exquisite preservation.

Species and Morphology Information:

• Species: Calycoceras (Newboldiceras) tunetanum
• Geological Age: Cenomanian, Cretaceous period (~100 to 94 million years ago)
• Depositional Environment: The Chalk Formation at Glynde was formed in shallow seas that covered much of the Earth during the Cretaceous period. The fine-calcium carbonate deposits formed over millions of years, providing an ideal environment for the fossilization of ammonites like Calycoceras.
• Morphology Features: The ammonite shell of Calycoceras is tightly coiled and smooth with well-defined sutures. This particular specimen showcases the distinctive spiral structure and chambered interior typical of this genus.
• Notable Features: This ammonite fossil displays exceptional preservation, with clear, detailed features including the whorls, sutural patterns, and the chambered structure of the ammonite. The specimen’s complete shell adds significant value for collectors and paleontologists alike.
• Family: Newboldiceras
• Superfamily: Ammonoidea
• Order: Ammonitida
• Biozone: The Cenomanian biozone is characterized by a rich variety of ammonoid species like Calycoceras, which thrived in the warm shallow seas of the Cretaceous period.
• Depositional Environment: The fossil was preserved in the Cretaceous shallow marine environment of Glynde, which offered ideal conditions for fossilization, especially for ammonoids.
