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) …

The Ediacaran–Cambrian (E–C) transition marks the most important geobiological
revolution of the past billion years, including the Earth's first crisis of macroscopic eukaryotic …

The rise of complex macroscopic life occurred during the Ediacaran Period, an interval that
witnessed large-scale disturbances to biogeochemical systems. The current Ediacaran …

The rise of animals occurred during an interval of Earth history that witnessed dynamic
marine redox conditions, potentially rapid plate motions, and uniquely large perturbations to …

The secular trend of seawater strontium isotope ratio (87 Sr/86 Sr) reflects changes in the
relative contributions of continental versus mantle reservoirs to ocean composition, and …

Abstract The Ediacaran-Cambrian transition, which incorporates the radiation of animals,
lacks a robust global temporal and spatial framework, resulting in major uncertainty in the …

Abstract The Ediacaran Shuram carbon isotope excursion (CIE) follows the regional
Gaskiers glaciation and occurs before the appearance of macroscopic animal fossils …

Abstract The Ediacaran Period follows the Cryogenian Period in the wake of a snowball
Earth glaciation and precedes the Cambrian Period with its rising tide of animal radiation. It …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

The role of O2 in the evolution of early animals, as represented by some members of the
Ediacara biota, has been heavily debated because current geochemical evidence paints a …
