    During the Cenozoic, mammals proliferated from a few small, simple, generalised forms into a diverse collection of terrestrial, marine, and flying animals, giving this period its other name, the Age of Mammals. The Cenozoic is just as much the age of savannas, the age of co-dependent flowering plants and insects, and the age of birds. [39]
