In geological time the Eon is larger than the Period. The Eon is the largest division of geological time recognised by the International Commission of Stratigraphic.
The ICS have divided the time as such from largest to smallest.
- Super-Eon - (SuperEonothem) (Not recognised by the ICS but unofficially recognised e.g. Precambrian time)
- Eon - (Eonothem)
- Era - (Erathem)
- Period - (System)
- Subperiod - (SubSystem)
- Epoch - (Series)
- Age - (Stage)
- Chron - (Chronozone) (Not recognised by the ICS but is unofficially recognised usually based on reversal of earths magnetic field)
An era is longer than a period. An era covers a longer span of time and may encompass multiple periods within it. Periods are shorter divisions of time, often within an era.

The Cretaceous period was a part of what era?
The Cretaceous period was part of the Mesozoic era.
The end of the Permian period was also the end of what Era?
The end of the Permian period marked the end of the Paleozoic Era and the beginning of the Mesozoic Era.
What geological era are we currently in?
We are currently in the Quaternary Period of the Cenozoic Era.
What geological era do we live in?
We live in the Quaternary period, which is part of the Cenozoic era.
Was era or period longer?
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.
Jurassic is the period of what era?
It really wasn't an era. An Era was a much longer period of time. It was called the "Jurassic Period".
Is A geologic era is a shorter unit of time than a geologic period?
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.

Is an era longer than a period?
Usually, an era refers to a specific time period, normally associated with the dates of an important event, while a period is often used to refer to events that share a characteristic, but do not have exact dates. The words are sometimes used interchangeably, and it isn't necessarily wrong to do so, since the usage is varied, but traditionally a period has been shorter than an era.
What is an era or period?
They are divisions of geologic time, based largely on the fossil record of organisms. Eras are longer subdivisions of time which are further subdivided into periods and epochs. For instance, we are currently in the Holocene epoch of the Quaternary Period, and the larger Cenozoic Era.
What is the name of the subdivisions of a qeologic period?
Eon --> Era --> sub-Era --> Period We are currently in: * Phanerozoic Eon * Cenozoic Era * Tertiary sub-Era * Quaternary Period
What era did the mesoproterozoic period begin?
the mesoproterozoic was an era itself not a period.
The Cretaceous period was a part of what era?
The Cretaceous period was part of the Mesozoic era.
In what geologic era is the Cretaceous Period found?
It is the final period of the Mesozoic era.
What is the 1st period in the Paleozoic Era?
The first period in the Paleozoic Era was the Cambrian.
The end of the Permian period was also the end of what Era?
The end of the Permian period marked the end of the Paleozoic Era and the beginning of the Mesozoic Era.
