Orogenic activity for the duration of the Cenozoic was
concentrated in the Alpine-Himalayan orogenic belt and the Circum-Pacific
orogenic belt. The Cenozoic Era is the current era animal history, which spans the
time period from 66 million years ago to the present day.
The order from the longest to the largest will be; Eon, Era, Period, Epoch.
Eon is the longest division of geologic time. Epoch is the shortest division of geologic time, only present in Cenozoic Era. Era is the second longest division of time, marked by sweeping changes in the fossil record. Period is the time division which is longer than an epoch but shorter than an Era.
