The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present. The Cenozoic is sometimes called the Age of Mammals, because the largest land animals have been mammals during that time. The tertiary geological period began with the death of non-avian dinosaurs (any dinosaurs that are not birds) in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to Quaternary glaciation at the end of the Pliocene Epoch. The dates have been further adjusted as Science advances when new evidence is found.

The Cenozoic Era—encompassing the past 66 million years, the time that has elapsed since the mass extinction event marking the end of the Cretaceous Period—has a broad range of climatic variation characterized by alternating intervals of global warming and cooling.
