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) …

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 …

Recurrent photic zone euxinia limited ocean oxygenation and animal evolution during the Ediacaran
Abstract The Ediacaran Period (~ 635–539 Ma) is marked by the emergence and
diversification of complex metazoans linked to ocean redox changes, but the processes and …

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 …

Proterozoic seawater sulfate scarcity and the evolution of ocean–atmosphere chemistry
Oceanic sulfate concentrations are widely thought to have reached millimolar levels during
