  • A. Pliocene epoch
    The Pliocene epoch was a geological time period roughly 5.3 to 2.6 million years ago marked by cooler global climates, the expansion of grasslands, and significant evolutionary developments among mammals and early hominins.
  • B. Paleogene
    The Paleogene is a geologic period that marks the beginning of the Cenozoic Era, characterized by the diversification of mammals and birds following the mass extinction that ended the age of dinosaurs.
  • C. Neogene
    The Neogene is a geologic period of the Cenozoic Era characterized by significant climatic cooling, the diversification of mammals and birds, and the emergence and evolution of early hominins.
  • D. Cenozoic
    The Cenozoic is the current geological era, beginning about 66 million years ago, characterized by the rise and diversification of mammals and birds and the formation of many modern mountain ranges and continents.
  • E. Pleistocene epoch
