Abstract The Ediacaran–Cambrian transition witnessed some of the most important
biological, tectonic, climatic and geochemical changes in Earth's history. Of utmost …

Stable isotope ratios combined with elemental compositions and molecular biomass data
provide a powerful tool in Neoproterozoic palaeoenvironmental interpretations. Here, we …

Ocean and atmosphere oxidation in the Ediacaran Period paved the way for the dawn of
animals. In an attempt to better document the record of seawater redox state at the onset of …

The sedimentary evolution of the Bambuí foreland basin system in the interior of West
Gondwana is marked by periods of connection and isolation from the global ocean during …

Abstract The Tamengo Formation (Corumbá Group, midwest Brazil) is a carbonate-
dominated succession of major importance to unravel the environmental and biological …

The appearance of the early biomineralized skeletons during the latest Ediacaran was one
of the most important evolutionary gains for the ancient animals' lineage. This evolutionary …

Biological innovations associated with geochemical disturbances characterize the
Ediacaran geological record, at the end of Neoproterozoic Era, which are attributed to the …

The Ediacaran is a period characterized by the diversification of early animals and extensive
neritic carbonate deposits. These deposits are still not well understood in terms of facies and …

Rare earth elements plus yttrium (REY) mass fractions of ancient carbonate rocks are used
to track changes in chemistry of past seawater. Here we investigate REY patterns in two …

Abstract The Bambui Group is a ca. 2,000 m-thick mixed biochemical-siliciclastic
sedimentary succession that accumulated in the Sao Francisco Basin, central Brazil. Its age …
