Neogene Period

The Neogene Period, spanning about 23 to 2.6 million years ago, is a division of Earth's geological timescale characterized by significant evolutionary and climatic changes. During this time, mammals and birds continued to diversify and modernize, while grasslands expanded, shaping ecosystems. The period saw the formation of important mountain ranges, like the Himalayas, and the cooling of Earth's climate, leading toward the ice ages. It laid the groundwork for the modern world’s flora, fauna, and climates, marking a crucial era in Earth's natural history.
