== In geology and Paleontology, an eon is the largest division of time. Eons are then divided into eras, and eras are divided into periods. So yes, an era is shorter than an eon. More And then periods are divided into series or epochs

Eon, Era, Period, Epoch (from largest to smallest)
The Archean Eon, which is part of the Precambrian period along with the Proterozoic Eon.
Eon --> Era --> sub-Era --> Period We are currently in: * Phanerozoic Eon * Cenozoic Era * Tertiary sub-Era * Quaternary Period
eon is the period now .

A Period
Eon, era, period. Our Earth Science teacher told us to remember it as MEEP: majors eon era period. MEEP.
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)
We currently live in the Holocene Epoch of the Quaternary Period of the Cenozoic Era of the Phanerozoic Eon.
I don't know the plural of eon but the answer is more than 1 eon
How long is an epoch? Longer than an era but shorter than an age of course!
Earth is currently in the Cenozoic Era of the Phanerozoic Eon.

The Longest Era of Earths History is Paleoproterozoic Eralasting 900 million years.The largest unit of time in relation to Earth's history is the super-eon. Super-eons are divided into eons. Eons in turn are divided into eras, eras are divided into periods, periods into Epochs and Epochs in Ages.Precambrian Super-Eon (4,600 - 542 Ma)Hadean Eon (4,600 - 3,800 Ma)Archean Eon (3,800 - 2,500 Ma)Eoarchean Era (3,800 - 3,600 Ma)Paleoarchean Era (3,600 - 3,200 Ma)Mesoarchean Era (3,200 - 2,800 Ma)Neoarchean Era (2,800 - 2,500 Ma)Proterozoic Eon (2,500 - 542 Ma)Paleoproterozoic Era (2,500 - 1,600 Ma)Mesoproterozoic Era (1,600 - 1,000 Ma)Neoproterozoic Era (1,000 - 542 Ma)Modern Super-Eon (542 Ma - Now)Phanerozoic Eon (542 Ma - now)Paleozoic Era (542 -251 Ma)Mezozoic Era (251 - 65 Ma)Cenozoic Era (65 Ma - Now)
