Eras are divided into periods.
A long span of geologic time is called an era. This is a major division of geologic time that is further subdivided into periods. Examples of eras include the Paleozoic, Mesozoic, and Cenozoic.
The Geologic Time Scale is divided up by four major intervals. In order from Largest to smallest: Eons are the largest time frame covering hundreds of millions of years. Eons are divided into smaller time intervals known as Eras. Eras are subdivided into Periods. Periods are broken into finer subdivisions known as Epochs.
Cenozoic Era
The geologic time scale is divided into four eras: the Precambrian, Paleozoic, Mesozoic, and Cenozoic eras. Each era represents a distinct span of time in Earth's history with characteristic geological and biological features.

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.
The span of geologic time subdivided into periods is called an era. Eras are further subdivided into periods to help scientists classify and study the Earth's history in a systematic way. Each period represents a distinct interval of time with its own set of characteristic geological and biological events.
Eras are subdivisions of larger units of geologic time called eons.
The largest division of time on the geologic time scale is an eon. Eons are subdivided into eras, which are further divided into periods, epochs, and ages. The current eon, the Phanerozoic, began around 541 million years ago and is divided into the Paleozoic, Mesozoic, and Cenozoic eras.
Eon is the broadest division on the geologic time scale, representing the longest time span. Eons are further divided into eras, which are then subdivided into periods, epochs, and ages.
The Geologic Time Scale is divided up by four major intervals. In order from Largest to smallest: Eons are the largest time frame covering hundreds of millions of years. Eons are divided into smaller time intervals known as Eras. Eras are subdivided into Periods. Periods are broken into finer subdivisions known as Epochs.
An eon is the longest geologic time period, typically lasting billions of years. It is subdivided into eras, which are further divided into periods, epochs, and ages.
The order of geologic time from smallest to largest is Phanerozoic, Proterozoic, Archean and Hadean (Deep Time). These four periods are called Eons which can be further subdivided into Eras, Periods and Epochs. Most people are more familiar with the periods such as Cambrian, Permian, Triassic, Jurassic and. Cretaceous and many more to numerous to mention. To learn more, Google geologic time scale.
