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)
