The Cenomanian rocks of Bohemia have yielded remains of a sub-tropical flora which has been compared with that existing at present in Australia.
In the province of Sergipe, on the east coast, the beds are approximately on the horizon of the Cenomanian; in the valley of the Amazon they belong to the highest parts of the Cretaceous system, and the fauna shows Tertiary affinities.
The Cretaceous beds have not yet been separated from the overlying Eocene, and the identification of the system rests on the discovery of a single Cenomanian ammonite.
Limestones and marls represent the stages Cenomanian to Upper Senonian.
The fossils of the Cenomanian have affinities with those in the Cenomanian of Spain, Egypt, Madagascar, Mozambique and India.
