The Age of Mammals
The Cenozoic Era, which began 66 million years ago and continues to the present, is widely known as the "Age of Mammals". This is because, following the extinction of the non-avian dinosaurs, mammals diversified and became the dominant land animals. The era is divided into three periods: the Paleogene, Neogene, and Quaternary.
The Cenozoic Era began after the Cretaceous-Paleogene extinction event 66mya, which wiped out the non-avian dinosaurs, creating ecological niches that mammals were able to fill.
