Abstract: Abstract The emergence and proliferation of metazoan lineage in the Ediacaran Period is commonly hypothesized to reflect an increase in the oxygen content of marine environments. However, recent studies suggest that the Ediacaran oceanic redox… read more here.

DOI: 10.1029/2025gl116574
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.
