Eocene epoch

The Eocene epoch, lasting from about 56 to 34 million years ago, was a period of significant global warming and ecological change. During this time, Earth's climate was generally warm and humid, supporting lush forests and diverse animal life, including early primates. Many modern plant and animal groups first appeared in the Eocene. The epoch saw the development of large forested areas in polar regions and the evolution of important mammals after the extinction of the dinosaurs. Overall, the Eocene was a formative time in shaping modern ecosystems and climate patterns.
