The Cenozoic Era, spanning from about 66 million years ago to the present, is known as the "Age of Mammals" due to the rise and diversification of mammals following the extinction of dinosaurs. This era also saw significant developments in plant life, particularly the spread of flowering plants, and the evolution of birds and insects. Major geological and climatic changes occurred, including the formation of mountain ranges and the establishment of modern ecosystems. Overall, the Cenozoic marked a period of significant biological and environmental transformation.
