Statherian

Also known as Statherian Period, Statherian System

The Statherian (; , meaning "stable, firm") is the fourth and final geologic period in the Paleoproterozoic Era, lasting from to million years ago (Ma) and spanning 200 million years. It follows the Orosirian Period and precedes the Calymmian Period, with the latter belonging to the Mesoproterozoic Era. Instead of being based on stratigraphy, these dates are defined chronometrically.

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.
