The great ice ages and atmospheric changes of the Precambrian, including the Huronian, Sturtian and Marinoan glaciations and the Great Oxidation Event that raised oxygen in the air. An event belongs here when its cited article describes a Precambrian glaciation or the rise of oxygen. It excludes later ice ages. Some of these glaciations may have covered the planet in ice, and they are dated from rock layers rather than from historical records.
