Petrographic carbon in ancient sediments constrains Proterozoic Era atmospheric oxygen levels
Oxygen concentration defines the chemical structure of Earth's ecosystems while it also fuels the metabolism of aerobic organisms. As different aerobes have different oxygen requirements, the evolution of oxygen levels through time has likely impacted both environmental chemistry and the histor...
