ClassificationEdit

  • Paleoproterozoic Era - Era that saw the Great Oxygenation Event, followed by the first Snowball Earth period.
    • Statherian Period (1.8-1.6 BYA) - Period that marked the beginning of the "Boring Billion" years, where oxygen levels dropped and evolution stagnated.
      • Event: Boring Billion (1.8-0.75 BYA) - Period where oxygen levels dropped and continued to decline and evolution stagnated. During this time, the Earth remained warm with no glaciations, despite supercontinent formation and breakup. The period shows unprecedented and unrepeated stability. Starts with development of Eukaryotes and ends with their diversification. Plate tectonics were stable during this time (little destruction of crust) and restarted at the end.
    • Orosirian Period
    • Rhyacian Period
    • Siderian Period (2.5-2.3 BYA) - First period of the Proterozoic Eon. The Great Oxygenation Event and beginning of the Huronian Ice Age occurred at this time.
