Cenozoic
Mammals became the dominant group of land animals soon after the start of the Paleocene Period, 64 million years ago.
Because it was during the Cenozoic (the current era of life) that mammals became the dominant group of large higher animals on the planet. The extinction of the dinosaurs made it possible for mammals to diversify and occupy many ecological niches.
The Tertiary period happened after the extinction that took place during the Cretaceous period, so mammals saw a great diversification, the most notable of which was the movement from eating from trees to eating grass. Along with these mammals, birds also became the dominant animals in land ecosystems.
The dinosaurs were the dominant land animals during the Jurassic and Cretaceous periods, rising to dominance during the late Triassic.

Fish and molluscs were the dominant creatures during the Devonian.
The Eocene Epoch was the second epoch of the Tertiary Period. During this time, mammals were the dominant form of animal life.
The Cenozoic era is known as the Age of Mammals because mammals became the dominant lifeform. This era is the one we live in today. Many things occurred during the era, including the formation of the Himalayas and the Pleistocene Ice Age that followed the overall cooling trend on the planet.
