Statherian
Template:Short description Template:Infobox geologic timespan The Statherian Period (Template:IPAc-en; Template:Langx, meaning "stable, firm") is the final geologic period in the Paleoproterozoic Era and lasted from Expression error: Unexpected round operator. Mya to Expression error: Unexpected round operator. Mya (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically.[1][2]
The period was characterized on most continents by either new platforms or final cratonization of fold belts. Oxygen levels were 10% to 20% of current values.[3]
Rafatazmia, controversially[4] claimed to be present in Statherian beds in India, may be the oldest known confirmably eukaryotic fossil organism.[5]
By the beginning of the Statherian, the supercontinent Columbia had assembled.[6]
Approximately 1.7 billion years ago, natural nuclear fission reactors were generating power in what is now Oklo, Gabon.[7]
