No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
An aquifuge is a geologic formation that does not transmit water, meaning it acts as a barrier to the flow of groundwater. Aquifuges are typically composed of impermeable materials such as clay or unfractured rock. They prevent the movement of water between aquifers, confining groundwater within certain boundaries.
Eon.
The smallest unit of time on the geologic time scale is an epoch, which typically lasts millions of years. It is used to divide periods into smaller segments based on significant changes in Earth's history.

Geologists measure geologic time in years.
The smallest unit of geologic time is an age, followed by epoch, period, era, eon, and super eon.
The name phot was coined in 1921 by Andre Blondel. The term is a metric that is used to measure illuminance. The unit is not always used and is still relatively new.
The smallest unit of geologic time is a "stage," which is typically defined by specific rock layers or fossils that mark distinct intervals of time within a geological period. Stages are further divided into ages, which correspond to even smaller intervals of time.
