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 …

The Ediacaran Period (635 to 542 million years ago) was a time of fundamental
environmental and evolutionary change, culminating in the first appearance of macroscopic …

The ocean‐atmosphere system is typically envisioned to have gone through a unidirectional
oxygenation with significant oxygen increases in the earliest (ca. 635 Ma), middle (ca. 580 …

The late Ediacaran to early Cambrian interval witnessed extraordinary radiations of
metazoan life. The role of the physical environment in this biological revolution, such as …

The rapid diversification of early animals during the Ediacaran (635–541 Ma) and early
Cambrian (ca. 541–509 Ma) has frequently been attributed to increasing oceanic …

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 …

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 …

Recent studies have enhanced our understanding of the linkage of oxygenation and
metazoan evolution in Early Cambrian time. However, little of this work has addressed the …

A growing number of detailed geochemical studies of Ediacaran (635–541 Ma) marine
successions have provided snapshots into the redox environments that played host to the …

Recent geochemical data from Oman, Newfoundland, and the western United States
suggest that long-term oxidation of Ediacaran oceans resulted in progressive depletion of a …
