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) …

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 …

Possible links between extreme oxygen perturbations and the Cambrian radiation of animals
The role of oxygen as a driver for early animal evolution is widely debated. During the
Cambrian explosion, episodic radiations of major animal phyla occurred coincident with …

Uranium isotope evidence for an expansion of anoxia in terminal Ediacaran oceans
Anoxic and iron-rich oceanic conditions prevailed throughout most of the Archean and

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 …
