Definition
The Geological History of the Cenozoic refers to the period spanning from approximately 66 million years ago to the present, characterized by significant geological, climatic, and biological changes, including the diversification of mammals and birds following the extinction of the dinosaurs. This era is divided into three epochs: the Paleogene, Neogene, and Quaternary, each marked by distinct evolutionary developments and environmental shifts.
Summary
The Cenozoic Era, beginning 66 million years ago, is marked by the rise of mammals and significant climatic changes. It is divided into three main periods: the Paleogene, Neogene, and Quaternary, each characterized by unique evolutionary developments and environmental shifts. The era has seen the emergence of diverse ecosystems and the impact of climate change on biodiversity. Understanding the Cenozoic is crucial for grasping the evolution of life on Earth, particularly the adaptations of mammals and the influence of plate tectonics. This era provides insights into how past climate changes can inform current and future ecological challenges, making it a vital area of study in geology and environmental science.
