Then Cenozoic Era is sometimes called the Age of Mammals, because the largest land animals have been mammals at this time.
Several of the world’s foremost mountain ranges, including the Alps, Himalayas and the Rocky Mountains, were formed during the Cenozoic Era.
Among the common plant life were pines, mosses, oaks and grasses.
Each period of the Cenozoic Era experienced a different climate.
The Paleogene Period marks the beginning of the Cenozoic Era. It began 65 million years ago and lasted more than 40 million years.
Paleogene Period (Climate and Geography)
In the beginning of the Paleogene Period the climate was very warm and moist compared to today's climate. Much of Earth was tropical at this time.
As for the changing landscape, the continents drifted apart during the Paleogene Period, creating vast stretches of oceans. This had a significant impact on the climate and marine life surrounding each continent.

- Dogs, Cats, pigs, toothed whales.
- Bats, Elephants, whales, Eohippus - The first horse.
- Condylarths - Ancestors of modern hoofed herbivores.
Due to the widening of the oceans,sharks, whales and other marine life proliferated. The Great Lakes that formed in the western United States during the Paleogene Period were the perfect home for bass, trout and other fresh-water species.
