Global marine redox evolution from the late Neoproterozoic to the early Paleozoic constrained by the integration of Mo and U isotope records
The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …

Redox changes in the outer Yangtze Sea (South China) through the Hirnantian Glaciation and their implications for the end-Ordovician biocrisis
Two pulses of faunal mortality occurred during the Late Ordovician mass extinction (ca. 445
Ma). This biocrisis is recorded in Hirnantian strata of South China as a stepwise extinction of …

Recurrent photic zone euxinia limited ocean oxygenation and animal evolution during the Ediacaran
Abstract The Ediacaran Period (~ 635–539 Ma) is marked by the emergence and
diversification of complex metazoans linked to ocean redox changes, but the processes and …

Spatial pattern of marine oxygenation set by tectonic and ecological drivers over the Phanerozoic
Marine redox conditions (that is, oxygen levels) impact a wide array of biogeochemical
cycles, but the main controls of marine redox since the start of the Phanerozoic about 538 …

Decoupled oxygenation of the Ediacaran ocean and atmosphere during the rise of early animals
Abstract The Ediacaran Period (∼ 635 to 541 Ma) witnessed the early diversification and
radiation of metazoans, in the form of the Ediacaran Biota. This biological revolution …

Occurrence and maturation transformation of organic and inorganic nitrogen in the Lower Cambrian shelf–slope facies shale: Implications for overmature N2-rich …
Thermogenic molecular nitrogen (N 2) is one of the primary sources of high N 2 content in
overmature shale gas reservoirs. However, it remains uncertain whether N 2 is released …

Upwelling-driven high organic production in the late Ediacaran
Abstract The Ediacaran ocean (635-541 million years ago) is typically viewed as a stagnant,
redox-stratified ocean with low phosphorus availability. However, this contradicts the high …
