DOI: 10.1016/j.epsl.2019.04.036
Abstract: Abstract The aftermath of end-Permian mass extinction was marked by a ∼5 million year interval of poorly-understood, extreme environments that likely hindered biotic recovery. Contemporary nitrogen isotope variations are considered, using a new conceptual model,… read more here.

DOI: 10.1016/j.palaeo.2017.08.038
Abstract: Abstract Extinction and delayed recovery during the end-Permian extinction and Early Triassic has been linked to environmental instability brought on by volcanic outgassing and greenhouse conditions, but the relative importance of the myriad of environmental… read more here.

DOI: 10.1016/j.palaeo.2018.11.030
Abstract: Abstract In this study, we reconstruct water-column oxygen availability during the deposition of Late Permian shales (Wuchiapingian to approximately early Changhsingian) using the geochemistry and morphology of sedimentary pyrite (FeS2). Deposition of the shales occurred… read more here.

DOI: 10.1038/s41467-017-00083-9
Abstract: Mass extinction events are short-lived and characterized by catastrophic biosphere collapse and subsequent reorganization. Their abrupt nature necessitates a similarly short-lived trigger, and large igneous province magmatism is often implicated. However, large igneous provinces are… read more here.

DOI: 10.1038/s41598-022-04991-9
Abstract: The role of ocean acidification in the end-Permian mass extinction is highly controversial with conflicting hypotheses relating to its timing and extent. Observations and experiments on living molluscs demonstrate that those inhabiting acidic settings exhibit… read more here.

DOI: 10.1126/sciadv.abq4082
Abstract: Massive carbon dioxide (CO2) emissions are widely assumed to be the driver of the end-Permian mass extinction (EPME). However, the rate of and total CO2 released, and whether the source changes with time, remain poorly… read more here.
