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) …

Oceanic oxygenation events in the anoxic Ediacaran ocean
The ocean‐atmosphere system is typically envisioned to have gone through a unidirectional
oxygenation with significant oxygen increases in the earliest (ca. 635 Ma), middle (ca. 580 …

Ocean oxygenation in the wake of the Marinoan glaciation
Metazoans are likely to have their roots in the Cryogenian period,,, but there is a marked
increase in the appearance of novel animal and algae fossils shortly after the termination of …

Calibrating the temporal and spatial dynamics of the Ediacaran-Cambrian radiation of animals
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 …

Uranium and molybdenum isotope evidence for an episode of widespread ocean oxygenation during the late Ediacaran Period
To improve estimates of the extent of ocean oxygenation during the late Ediacaran Period,
we measured the U and Mo isotope compositions of euxinic (anoxic and sulfidic) organic …
