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 drivers of Ediacaran-Cambrian metazoan radiations remain unclear, as does the fidelity
of the record. We use a global age framework [580–510 million years (Ma) ago] to estimate …

Abstract The Ediacaran–Cambrian transition marks one of the most important geobiological
revolutions in Earth History, including multiple waves of evolutionary radiation and …

Euarthropoda is one of the best-preserved fossil animal groups and has been the most
diverse animal phylum for over 500 million years. Fossil Konservat-Lagerstätten, such as …

Animals originated and evolved during a unique time in Earth history—the Neoproterozoic
Era. This paper aims to discuss (1) when landmark events in early animal evolution …

Analysis of modern animals and Ediacaran trace fossils predicts that the oldest bilaterians
were simple and small. Such organisms would be difficult to recognize in the fossil record …

The advent of animal (metazoan) biomineralization marks a fundamental transition in Earth's
history, facilitating the diversification of novel body plans as well as the biological control of …

The transition from the terminal Ediacaran to early Cambrian (ca. 550–530 Ma) witnessed
both the decline of Ediacaran-type soft-bodied and skeletal biota and the rapid …
