The 3 eras of geologic time is Palezozoic era, Mesozoic era, and Cecozoic era
The Phanerozoic era.
After an era, the next smallest division of time would be an epoch. An epoch is equal to around 10,000,000 years, where as an era is 100,000,000 years.
An era is a period of geologic time which varies in length but is many millions of years. For instance, the current era of geologic time, the Cenozoic, has lasted for over 65 million years to date.
The order of the geologic time intervals is Eon, Era, Period, Epoch.

Era
The current geological era is the Cenozoic Era (65.5ma to now).
On the geologic time scale, an era is longer than a period. There are 12 geologic eras in total and they are composed of geologic periods. For instance, the Mesozoic era is composed of the Triassic, Jurassic and Cretaceous periods.
The order of the geologic time intervals is Eon, Era, Period, Epoch.
