- The case for a Neoproterozoic Oxygenation Event: Geochemical evidence and biological consequences (2011, background): “…reduced atmospheric oxygen levels between 2.45 and 1.9 Ga. BIFs deposited during the late Neoproterozoic between ca. 750 Ma and the Precambrian-Cambrian boundary record strongly positive δ53Cr values ranging from 0.9‰ to 4.9‰, which may provide further evidence for the NOE (from Frei et al., 2009).”
- The Ecological Physiology of Earth's Second Oxygen Revolution (2015, background): “Persistent oxygenation of the atmosphere and surface ocean began ∼2,400 Mya, perhaps increasing transiently to relatively high levels (Lyons et al. 2014).”
