The major animal group that replaced dinosaurs and reptiles in the Cenozoic era were mammals. The mammals that replaced them consist of bats, whales, all hoofed animals like horses and elk, rodents carnivores and finally primates. This age became known as the age of the mammals due to all of the new evolution taking place. (Source)
