Oxygenation, life, and the planetary system during Earth's middle history: An overview
The long history of life on Earth has unfolded as a cause-and-effect relationship with the
evolving amount of oxygen (O2) in the oceans and atmosphere. Oxygen deficiency …

Oceanic oxygenation events in the anoxic Ediacaran ocean
The ocean‐atmosphere system is typically envisioned to have gone through a unidirectional
oxygenation with significant oxygen increases in the earliest (ca. 635 Ma), middle (ca. 580 …

Extensive marine anoxia during the terminal Ediacaran Period
The terminal Ediacaran Period witnessed the decline of the Ediacara biota (which may have
included many stem-group animals). To test whether oceanic anoxia might have played a …

A highly redox-heterogeneous ocean in South China during the early Cambrian (∼ 529–514 Ma): Implications for biota-environment co-evolution
Abstract The “Cambrian Explosion” is known for rapid increases in the morphological
disparity and taxonomic diversity of metazoans. It has been widely proposed that this …
