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) …

Rise to modern levels of ocean oxygenation coincided with the Cambrian radiation of animals
The early diversification of animals (∼ 630 Ma), and their development into both motile and
macroscopic forms (∼ 575–565 Ma), has been linked to stepwise increases in the …

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 …

Uranium and molybdenum isotope evidence for an episode of widespread ocean oxygenation during the late Ediacaran Period
To improve estimates of the extent of ocean oxygenation during the late Ediacaran Period,
we measured the U and Mo isotope compositions of euxinic (anoxic and sulfidic) organic …

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 …

Molybdenum isotope-based redox deviation driven by continental margin euxinia during the early Cambrian
Oceanic redox changes may be a key environmental trigger for the “Cambrian explosion”.
However, a hypothesized predominantly oxygenated early Cambrian ocean, inferred from …

Coupled molybdenum, iron and uranium stable isotopes as oceanic paleoredox proxies during the Paleoproterozoic Shunga Event
Abstract The Paleoproterozoic Era was a time of remarkable importance in the redox
evolution of Earth's atmosphere and oceans. Here, we present a multi-proxy study of Mo, U …
