Integrated records of environmental change and evolution challenge the Cambrian Explosion
Abstract The 'Cambrian Explosion'describes the rapid increase in animal diversity and
abundance, as manifest in the fossil record, between~ 540 and 520 million years ago (Ma) …

On the co‐evolution of surface oxygen levels and animals
Few topics in geobiology have been as extensively debated as the role of Earth's
oxygenation in controlling when and why animals emerged and diversified. All currently …

Uncovering the Ediacaran phosphorus cycle
Phosphorus is a limiting nutrient that is thought to control oceanic oxygen levels to a large
extent,–. A possible increase in marine phosphorus concentrations during the Ediacaran …

Extreme variability in atmospheric oxygen levels in the late Precambrian
Mapping the history of atmospheric O2 during the late Precambrian is vital for evaluating
potential links to animal evolution. Ancient O2 levels are often inferred from geochemical …

Sea level controls on Ediacaran-Cambrian animal radiations
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 …

Global marine redox evolution from the late Neoproterozoic to the early Paleozoic constrained by the integration of Mo and U isotope records
The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …

Global marine redox changes drove the rise and fall of the Ediacara biota
The role of O2 in the evolution of early animals, as represented by some members of the
Ediacara biota, has been heavily debated because current geochemical evidence paints a …

Uranium isotopes in marine carbonates as a global ocean paleoredox proxy: a critical review
The protracted oxygenation of the ocean-atmosphere system is one of the most fundamental
changes to the Earth system through its history. The uranium isotopic composition (238 …
