- 1. The Tertiary Period, also known as the Cenozoic Era's first phase, spans from approximately 66 million years ago to about 2.6 million years ago, encompassing an incredible chapter in Earth's geological history characterized by significant evolutionary developments and climatic changes. This period is divided into the Paleogene and Neogene, each consisting of several epochs, during which the planet saw the rise of mammals as the dominant terrestrial vertebrates following the mass extinction that wiped out the dinosaurs. Throughout the Tertiary Period, the climate fluctuated from warm and humid conditions, conducive to the flourishing of lush forests and rich biodiversity, to cooler and drier phases that led to the formation of grasslands and savannas. This era also witnessed the emergence of key modern mammal groups, including primates, cetaceans, and many large herbivores and carnivores, as well as the development of flowering plants, which transformed the landscapes across continents. The tectonic activities of this time, including the uplift of mountain ranges such as the Himalayas and the Rockies, played a crucial role in shaping habitats and influencing patterns of evolution. The Tertiary Period set the stage for the Pleistocene Epoch and the Ice Ages that followed, marking profound changes in ecosystems and paving the way for the continued evolution of species, including the ancestors of humans.
