Global marine redox evolution from the late Neoproterozoic to the early Paleozoic constrained by the integration of Mo and U isotope records
The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …

Decoupled oxygenation of the Ediacaran ocean and atmosphere during the rise of early animals
Abstract The Ediacaran Period (∼ 635 to 541 Ma) witnessed the early diversification and
radiation of metazoans, in the form of the Ediacaran Biota. This biological revolution …
