Neogene Period
23-2.6 million years ago
About this Period
Modern mammals and grasslands emerge
Detailed Overview
The Neogene period was characterized by major geological and climatic changes that shaped the modern world. Global cooling led to the expansion of grasslands and savannas, which prompted significant evolution in grazing mammals. This period saw the development of many modern mammals, including horses, elephants, and great apes. The cooling trend also led to the formation of ice caps at the poles and the emergence of seasonal climates similar to those we experience today.
