Abstract: Phanerozoic extinctions may have been influenced by oceanic redox oscillations, as indicated by mixing‐induced negative pyrite Δ33S (Δ33Spy). However, the frequencies, intensities, and timescales of these oscillations remain elusive. Here, we measured stratigraphic Δ33Spy from… read more here.
