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 geologically rapid appearance of fossils of modern animal phyla within Cambrian strata
is a defining characteristic of the history of life on Earth. However, temporal calibration of the …

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 Distinctive uppermost Ediacaran–Ordovician rocks (Avalonian overstep sequence)
were key in definition of Avalonia, which comprises large areas of the NE Appalachians and …

Milankovitch cycles are quasi-periodic fluctuations in insolation forced by the variation in
Earth's astronomical parameters. The astronomically induced climate change affected the …

The correlation between Neoproterozoic tectonics, paleoenvironment and early life are
crucial for understanding the evolution of the Earth's habitability. The Yangtze Block …

The diversification of animals during the Cambrian Period is one of the most significant
evolutionary events in Earth's history. However, the sequence of events leading to the origin …

Age determination of minerals using the U–Pb technique is widely used to quantify time in
Earth's history. A number of geochronology laboratories produce the highest precision U–Pb …
