Why is the Cenozoic era is called the age of mammals?
The Cenozoic Era (65 million years ago to now) is known as the age of the mammals because this is the period where mammals came to dominate most environments on Earth. Although true mammals evolved in the late Triassic Period about 200 million years ago but where generally thought to be small and most certainly overshadowed by Reptiles such as Dinosaurs. When the Dinosaurs and most other large reptiles died out 65 million years ago, mammals started to become more dominant filling the ecological niches that where filled by large reptiles. Likewise Angiosperms (flowering plants) also shared similar fortunes. Many environments. There was a marked shift from Gymnosperms such as ferns and cycads to flowering plants.
