Today I learned there may have been macroscopic organisms 2.1 billion years ago, the Francevillian biota. Might have thrived during the great oxygenation event and then died out during the Lomagundi event, looong before the Ediacaran biota 600 Mya. https://t.co/qi107DkwXs

Abstract in brief
- The Paleoproterozoic Era saw significant changes in Earth's surface environments, notably with the increase in atmospheric oxygen around 2.3 billion years ago, which led to oxygenated shallow oceans and the emergence of early complex life.
- The Francevillian B Formation in Gabon contains well-preserved black shales from about 2.1 billion years ago that have not been heavily altered by heat or pressure, revealing centimeter-sized structures believed to be organized colonies of early marine organisms.
- Combining various analytical methods, researchers found diverse macrofossils and organic remains suggesting these organisms fossilized during early diagenesis, supporting the idea that rising oxygen levels fostered the development and diversity of complex life forms at that time.]
