The Cenozoic era comprises two divisions,-theTERTIARY period and the QUATERNARY period.

These two ages are called the Mesozoic or Secondary, and the Cenozoic or Tertiary.

Representatives of the foraminifer Nummulites are important in Earth history for timing Cenozoic shallow-water carbonates.
4
The Cenozoic era had volcanic activity and geological unrest.

In geologic time, the beds are a part of the Oligocene epoch of the Cenozoicera.

The Mesozoic era has three periods, the Triassic, Jurassic and Cretaceous, while the Cenozoicera names five periods,-theEocene, Oligocene, Miocene, Pliocene and Pleistocene.
