Calycoceras is a genus of extinct ammonoid cephalopods, marine mollusks that thrived in the warm, shallow seas of the Late Cretaceous. Belonging to the subclass Ammonoidea, these organisms are known for their coiled, chambered shells and intricate suture patterns. Calycoceras species are especially notable for their ribbed and sometimes tuberculate shell ornamentation, making them striking specimens for both scientific study and display.
The Cenomanian stage (approximately 100.5 to 93.9 million years ago) marks the beginning of the Late Cretaceous, a time of high sea levels and flourishing marine biodiversity. The chalk deposits of Shapwick Grange represent sediment accumulation in a warm epicontinental sea, providing ideal conditions for fossil preservation.
