Classification[]

  • Prenephelean Eon (44.5-4.68 BYA) - A proposed Eon representing the time before Earth formed. Starts with the Big Bang and ends with the formation of the Solar System. A proposal in 2012 suggested moving the time spanned by the Neochaotian Era to the Hadean and redubbed the Chaotian Era, which would leave the Eochaotian Era as part of the preceeding Eon, which could be dubbed the "Prechaotian".
    • Neoprenephelean Era (13.6-4.68 BYA) - Time after the first structures were formed until the Solar Nebula collapsed.
    • Eoprenephelean Era (13.750-13.600 BYA) - The first period of the Universe after the Big Bang (sometimes even periods before this is included). The time before the first structures.
