And so the Cenozoic era continues. It is the era we live in, though we could hardly say this is the era of humans. We have been present as a species only about 1.5 million years of the 65 million of the current era. That represents about 7 seconds on the clock of eras!

The period between the extinction of the dinosaurs and the present day is called the Age of Mammals or Cenozoic. Mammals appeared on the earth long before the extinction of the dinosaurs; in fact, dinosaurs and mammals originated within 10 million years of each other, in the late Triassic about 200 million years ago.

During the Cenozoic era (the last 66 million years), there was a gradual lowering of temperatures as well as the gradual establishment of different climatic zones of the earth -the tropics, the temperate zones and the cool climates of the higher latitudes.

Neogene Period, Cenozoic Era, Phanerozoic Eon [23 Myr - 1.8 Myr ] In the time scale of Lutgens & Tarbuck, the Neogene Period and the Paleogene Period below are combined and called the Tertiary Period. Calling this span from roughly 66 Myr to 1.8 Myr the Tertiary Period is fairly common in geologic literature. It is sometimes referred to as the age of mammals.

The further subdivision of the eras into 12 periods is based on identifiable but less profound changes in life-forms. In the most recent era, the Cenozoic, there is a further subdivision of time into epochs.

The Cenozoic Era. The Cenozoic era, meaning new life is also known as the Age of Mammals, just as the Mesozoic era was the Age of Reptiles. The Cenozoic spans the time period covered from the final extinction at the end of the Cretaceous, approximately 65 million years ago, to the present. Paleogene (65-23 Ma)

While none of the mammals ever reached the size of the dinosaurs, there were some species that dwarfed their modern-day relatives. Everyone knows about mammoths, but during the Cenozoic Era some birds stood 7-feet tall. There were beavers 7 feet long! These creatures were typical of the growth achieved by the “new life” in the early Cenozoic. Flowering Plants. Flowering plants or angiosperms were widespread in the Cenozoic Era.
