Total organic carbon, organic phosphorus, and biogenic barium fluxes as proxies for paleomarine productivity
Although marine productivity is a key parameter in the global carbon cycle, reliable
estimation of productivity in ancient marine systems has proven difficult. In this study, we …

Marine productivity changes during the end-Permian crisis and Early Triassic recovery
J Shen, SD Schoepfer, Q Feng, L Zhou, J Yu… - Earth-Science …, 2015 - Elsevier
The latest Permian mass extinction (LPME) coincided with major changes in the composition
of marine plankton communities, yet little is known about concurrent changes in primary …

Marine anoxia and delayed Earth system recovery after the end-Permian extinction
Delayed Earth system recovery following the end-Permian mass extinction is often attributed
to severe ocean anoxia. However, the extent and duration of Early Triassic anoxia remains …

Ocean acidification and the Permo-Triassic mass extinction
Ocean acidification triggered by Siberian Trap volcanism was a possible kill mechanism for
the Permo-Triassic Boundary mass extinction, but direct evidence for an acidification event …

Reconstruction of secular variation in seawater sulfate concentrations
Long-term secular variation in seawater sulfate concentrations ([SO 4 2−] SW) is of interest
owing to its relationship to the oxygenation history of Earth's surface environment. In this …

Multiple episodes of extensive marine anoxia linked to global warming and continental weathering following the latest Permian mass extinction
Explaining the~ 5-million-year delay in marine biotic recovery following the latest Permian
mass extinction, the largest biotic crisis of the Phanerozoic, is a fundamental challenge for …

Anoxia/high temperature double whammy during the Permian-Triassic marine crisis and its aftermath
Abstract The Permian-Triassic mass extinction was the most severe biotic crisis in the past
500 million years. Many hypotheses have been proposed to explain the crisis, but few …

Resilience of infaunal ecosystems during the Early Triassic greenhouse Earth
The Permian-Triassic mass extinction severely depleted biodiversity, primarily observed in
the body fossil of well-skeletonized animals. Understanding how whole ecosystems were …

Biosedimentological features of major microbe-metazoan transitions (MMTs) from Precambrian to Cenozoic
Biotic activities are involved in almost all sedimentation processes throughout the
evolutionary history of life on our planet. However, deep-time organism-induced …
