Adaptation and evolution, along with the extinction of the dominant land animals of the late Mesozoic.
The Age of Mammals is the other name for the Cenozoic Era. The Cenozoic Era lasted for 65 million years.
The Cenozoic Era. This began 65.5 million years ago.
During the Cenozoic era, mammals flourished, with the emergence of many modern groups such as primates, rodents, and hoofed mammals. Birds also diversified, along with flowering plants and insects. Additionally, marine life saw the rise of modern fish and marine mammals like whales and dolphins.
The three eras of geologic time are the Paleozoic, Mesozoic, and Cenozoic eras. The Paleozoic era is known for the development of marine life, the Mesozoic era is often referred to as the "Age of Dinosaurs," and the Cenozoic era is characterized by the diversification of mammals and the rise of humans.
There was no one dominant species throughout the Cenozoic, as it was a period of time that stretched from the extinction of the dinosaurs 65 million years ago to the present day, with many changes in climate that would hinder the ability of any one species to be dominant. However, it is perfectly sensible to say that mammals were dominant since the start of the Cenozoic. Mammals at the time of the dinosaurs (the Jurassic and Cretaceous, mostly) were mostly very small scavengers and herbivores. The extraterrestrial impact and flood basalt outpourings that killed the dinosaurs and many other species left mostly animals under 10kg in weight - chief among them the mammals. With no larger predators to kill them, the mammals took the evolutionary opportunity and flourished, leading us to become the dominant species we are today.

The Cenozoic is known as the Age of Mammals.
Mammals first evolved during the Mesozoic, the age of dinosaurs. After the dinosaurs died out, the Cenozoic began and mammals diversified until they dominated the land. Currently, we still live in the Cenozoic, so, technically, the Cenozoic could be called "the age of mammals."
"The Age of Mammals" is the nickname for the Cenozoic Era, which was formerly known as the Tertiary Period. It is characterized by the dominance and diversification of mammals on Earth.

An event that happened would be the ending of the Ice age and the beginning of mammals and plants, or even the formations of the major landforms we have today. Such as the beginning of the Alps, or the Himalayas. The pollen and fruit count even increased through the Cenozoic Era.

Mammals .
the extinction of dinosaurs created an opportunity for mammals. Another thing that created an opportunity for mammals in the Cenozoic Era was the fact that they evolved so quickly because they had no limiting factors.
Mammals became the dominant land animals in the early Paleocene period of the Cenozoic era, after the extinction of the non-avian dinosaurs at the end of the Cretaceous period of the Mesozoic era.
