The Cenozoic Era: Dawn of Mammals and Modern Landscapes

The Cenozoic Era, starting 65 million years ago, is known as the age of mammals. It is divided into the Paleogene, Neogene, and Quaternary periods. During the Paleogene, the climate was tropical, and mammals diversified. The Neogene saw the emergence of early humans and other primates. The Quaternary was marked by glaciations and the rise of modern species. The era significantly influenced plant and animal evolution, shaping today's biodiversity. Geological changes included the formation of major mountain ranges and the Great Lakes. Fossils provide insights into this era, though they leave some questions unanswered.
