The approximately 2,220–2,060 million years old Lomagundi–Jatuli Event was the longest positive carbon isotope excursion in Earth history and is traditionally interpreted to reflect an increased organic carbon burial and a transient rise in atmospheric O 2 . However, it is widely held that O 2 levels collapsed for more than a billion years after this. Here we show that black shales postdating the Lomagundi–Jatuli Event from the approximately 2,000 million years old Zaonega Formation contain the… Expand

Oxygenation, Life, and the Planetary System during Earth's Middle History: An Overview
TLDR
The geochemical records of Earth's middle history is focused on, as a backdrop for exploring possible cause-and-effect relationships with biological evolution and the primary controls that may have set its pace, including solid Earth/tectonic processes, nutrient limitation, and their possible linkages.

Using modern low-oxygen marine ecosystems to understand the nitrogen cycle of the Paleo- and Mesoproterozoic oceans.
TLDR
Geologic information about the Proterozoic ocean to microbial processes in modern low oxygen systems is linked, finding high iron concentrations and rates of Fe cycling in the Proteozoic are the largest differences from modern oxygen deficient zones. Expand

Ocean oxygenation in the wake of the Marinoan glaciation
TLDR
The data provide evidence for an early Ediacaran oxygenation event, which pre-dates the previous estimates for post-Marinoan oxygenation by more than 50 million years, and seem to support a link between the most severe glaciations in Earth’s history, the oxygenation of the Earth's surface environments, and the earliest diversification of animals.
