RARE: Cenoceras radiatus Fossil Nautilus – Lower Cenomanian, Cretaceous – France – COA

Description

This is a rare and well-preserved Cenoceras radiatus fossil nautilus from the Lower Cenomanian Stage of the Cretaceous (~100 million years ago). It was discovered in France, a region known for its exceptional fossil deposits from the Late Mesozoic era.

Cenoceras radiatus is an extinct species of nautiloid cephalopod, characterized by its distinctive coiled shell and radiating growth lines. Unlike ammonites, which have intricate suture patterns, nautiloids like Cenoceras have simpler internal chamber structures, making them an important evolutionary link between ancient and modern cephalopods.
