The ocean enabled the diversification of life on Earth by adding O2 to the atmosphere, yet
marine species remain most subject to O2 limitation. Human industrialization is intensifying …

Understanding causal relationships between evolution and ocean oxygenation hinges on
reliable reconstructions of marine oxygen levels, typically from redox-sensitive geochemical …

Two records of Earth history capture the evolution of life and its co-evolving ecosystems with
interpretable fidelity: the geobiological and geochemical traces preserved in rocks and the …

Anthropogenic climate change is increasing rapidly and already impacting biodiversity.
Despite its importance in future projections, understanding of the underlying mechanisms by …

Oxygen bioavailability is declining in aquatic systems worldwide as a result of climate
change and other anthropogenic stressors. For aquatic organisms, the consequences are …

Using Gondwana as an example, we show how the geological record can be interrogated to
detect significant changes in mantle convection patterns at critical junctures in Earth's …

The advent of bioturbation in the early Paleozoic and the subsequent intensification of
sediment mixing by benthic animals dramatically altered marine ecosystems and …

Abstract The Upper Ordovician (Katian) Neda Formation, a phosphatic ironstone, records a
widespread but short‐lived shift to ferruginous waters across a vast epicontinental area …

Current research indicates that (sub) surface ocean worlds essentially devoid of subaerial
landmasses (eg, continents) are common in the Milky Way and that these worlds could host …

ABSTRACT The lower Nama Group in southern Namibia contains trace fossils and soft‐
bodied and biomineralized macro‐organisms from the terminal Ediacaran Period (ca 550 to …
