What are the 6 consecutive ages of the Cenozoic?
Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene,
What arose during the Paleocene?
fish populations, sophisticated reptiles, first modern plants
Eocene
During this epoch the first primates that resemble living species evolved. By the end of this epoch most of the modern orders of mammals had evolved. Anthropoids diversified greatly.
Oligocene
Global cooling marked the start of the Oligocene, an environmental shift that led to changes in the flora and fauna. During this epoch archaic species of the early Cenozoic were replaced by modern herbivores, such as horses, camels and deer, and carnivores such as cats and dogs.
Miocene
first true apes and Old World monkeys. The Miocene was a time of great mammalian diversity, and many species originated and became extinct in response to environmental change.
Pliocene
first bipedal ancestors of humans are known to have evolved. Dramatic cooling and a drop in sea level impacted both marine and terrestrial life at the start of the epoch.
Pleistocene
Ice Age. Modern humans evolved and spread throughout the world during the Pleistocene.
