The repeated association during the late Neoproterozoic Era of large carbon-isotopic excursions, continental glaciation, and stratigraphically anomalous carbonate precipitation provides a framework for interpreting the reprise of these conditions on the Late Permian Earth. A paleoceanographic model that was developed to explain these stratigraphically linked phenomena suggests that the overturn of anoxic deep oceans during the Late Permian introduced high concentrations of carbon dioxide into… 
Large Perturbations of the Carbon Cycle During Recovery from the End-Permian Extinction
High-resolution carbon isotope measurements of multiple stratigraphic sections in south China demonstrate that the pronounced carbon isotopic excursion at the Permian-Triassic boundary was not an
Isotopes, ice ages, and terminal Proterozoic earth history.
Detailed correlations of ancient glacial deposits, based on temporal records of carbon and strontium isotopes in seawater, indicate four (and perhaps five) discrete ice ages in the terminal
Abrupt and Gradual Extinction Among Late Permian Land Vertebrates in the Karoo Basin, South Africa
TLDR
The vertebrate fossil data show a gradual extinction in the Upper Permian punctuated by an enhanced extinction pulse at the Permians-Triassic boundary interval, particularly among the dicynodont therapsids, coinciding with negative carbon-isotope anomalies.
Carbon isotope anomaly and other geochemical changes at the Triassic-Jurassic boundary from a marine section in Hungary
Most mass extinctions are linked with carbon isotope excursions, implying that biotic crises are coupled with changes in the global carbon cycle. The isotopic evolution during the end-Triassic
The Source and Fate of Massive Carbon Input During the Latest Paleocene Thermal Maximum.
TLDR
The deposition of a mud clast interval and seismic evidence for slope disturbance provide evidence to confirm the gas hydrate dissociation hypothesis and identify the Blake Nose as a site of methane release.
A neoproterozoic snowball earth
Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial deposits in Namibia, combined with estimates of thermal subsidence history, suggest that biological productivity
Multiple Permian-Triassic life crises on land and at sea
Abstract The largest mass extinction in the history of life was during the Late Permian, ca 252 Ma. New evidence from stable isotopic composition and Bk metrics of paleosols from the Late Permian to
Paleoceanographic and paleoclimatic context of Early Triassic time
Abstract The Early Triassic interval is dominated by unusual oceanic and climatic conditions that are perhaps unique to the Phanerozoic. Early Triassic oceans were likely anoxic and possibly alkaline
Phosphorus, nitrogen, and the redox evolution of the Paleozoic oceans
A new high-resolution Paleozoic d 13 Ccarb curve from the Great Basin shows an amount of variation that appears transitional between the highly unsettled Neoproterozoic and the increasingly stable
End-Permian Mass Extinction in the Oceans: An Ancient Analog for the Twenty-First Century?
The greatest loss of biodiversity in the history of animal life occurred at the end of the Permian Period (∼252 million years ago). This biotic catastrophe coincided with an interval of widespread
