Iron isotopes and the redox evolution of Ediacaran sediments

The Ediacaran age (ca. 570 Ma) Shuram excursion, a ca. $12‰$ depletion in $\delta ^{13}\mathrm{C}_{\mathrm{carb}}$, may record a dramatic oxidation of marine sediments associated with a reorganization of Earth’s carbon cycle closely preceding the rise of large metazoans.
