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 …

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 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 emergence of the Ediacara biota soon after the Gaskiers glaciation ca. 580 million years
ago (Ma) implies a possible glacial fuse for the evolution of animals. However, the timing of …

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

The morphologically differentiated benthic macrofossils of algae and putative animal
affinities of the Lantian biota in China represents the oldest known Ediacaran macroscopic …

The popularity of relaxed clock Bayesian inference of clade origin timings has generated
several recent publications with focal results considerably older than the fossils of the clades …

Molecular timescales estimate that early animal lineages diverged tens of millions of years
before their earliest unequivocal fossil evidence. The Ediacaran macrobiota (~ 574 to 538 …

The driving forces behind the evolution of early metazoans are not well understood, but key
insights into their ecology and evolution can be gained through ecological analyses of the in …
