With large dinosaurs now extinct, smaller mammals that had survived were able to grow and become dominant. The climate changed drastically over a relatively short period of time, becoming much cooler and drier than during the Mesozoic Era. 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.
