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 …

Integrated records of environmental change and evolution challenge the Cambrian Explosion
Abstract The 'Cambrian Explosion'describes the rapid increase in animal diversity and
abundance, as manifest in the fossil record, between~ 540 and 520 million years ago (Ma) …

Uncovering the Ediacaran phosphorus cycle
Phosphorus is a limiting nutrient that is thought to control oceanic oxygen levels to a large
extent,–. A possible increase in marine phosphorus concentrations during the Ediacaran …

The evolution of Earth's biogeochemical nitrogen cycle
Nitrogen is an essential nutrient for all life on Earth and it acts as a major control on
biological productivity in the modern ocean. Accurate reconstructions of the evolution of life …

Continental configuration controls ocean oxygenation during the Phanerozoic
The early evolutionary and much of the extinction history of marine animals is thought to be
driven by changes in dissolved oxygen concentrations ([O2]) in the ocean,–. In turn,[O2] is …

Calibrating the coevolution of Ediacaran life and environment
The rise of animals occurred during an interval of Earth history that witnessed dynamic
marine redox conditions, potentially rapid plate motions, and uniquely large perturbations to …

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 …
