Oxygen dynamics in the aftermath of the Great Oxidation of Earth’s atmosphere
Significance The Great Oxidation of Earth’s atmosphere about 2.3 billion years ago began a series of geochemical events leading to elevated oxygen levels for the next 200 million years, with aExpand

The 2.1 Ga Old Francevillian Biota: Biogenicity, Taphonomy and Biodiversity
The Paleoproterozoic Era witnessed crucial steps in the evolution of Earth's surface environments following the first appreciable rise of free atmospheric oxygen concentrations ∼2.3 to 2.1 Ga ago,Expand

Origin of red beds in the Paleoproterozoic Franceville Basin, Gabon, and implications for sandstone-hosted uranium mineralization
Red beds are extensively used as evidence for an oxygenated atmosphere in the Paleoproterozoic. Red beds in the unmetamorphosed, ca. 2.15 Ga FA Formation of the Franceville Basin, Gabon wereExpand

Collective behaviour in 480-million-year-old trilobite arthropods from Morocco
Interactions and coordination between conspecific individuals have produced a remarkable variety of collective behaviours. This co-operation occurs in vertebrate and invertebrate animals and is wellExpand

Precise U-Pb age constrains on the Ediacaran biota in Podolia, East European Platform, Ukraine
The Neoproterozoic Era was characterized by rapidly changing paleogeography, global climate changes and especially by the rise and fall of the Ediacaran macro-biota. The correlation between disparateExpand
