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.
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.

Cenozoic era
Yes and, as we are still in the Cenozoic Era, it continues to this day.
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.
