Eochaotian Era Web PagesEdit
- Chaotian Eon (4.68-4.5 BYA) - A proposed Eon marking the beginnings of Earth as a planet up until the collision that formed the Moon. A later 2012 proposal divided this Eon between the Hadean and Prechaotian Eons.
- Neochaotian Era (4.567-4.500 BYA) - Later part of the proposed Chaotian. Begins when the Sun first emitted light and ends when Theia collided with Tellus, forming the Earth and Moon. Later proposed to be moved to the Hadean Eon as the Chaotian Era.
- Eochaotian Era (4.680-4.567 BYA) - Early part of the proposed Chaotian Eon. Later proposed to be moved to the first Eon, which was renamed the Prechaotian, and redubbed the Neoprechaotian.
