Nautiloid Cimomia pernambucensis

As an abundant animal in the fossil record, this group is present in narratives from different cultures around the world. In addition, the shape of their shells made many believe that these molluscs were petrified snakes. However, the fossiliferous record indicates that the ammonites were molluscs that became extinct along with the dinosaurs, at the end of the Cretaceous, 66 million years ago.
