2014) indicate stable temperatures in the pre-extinction phase of the late Permian (Fig. 3D). A gradual pre-extinction warming, as indicated by the ostracod-based data, was also suggested from brachiopod data in South China (Wang et al. 2020), but this observation is based on a very limited number of specimens in this key time interval.

It has been widely accepted that there was a negative carbon isotope excursion (CIE) in the global ocean–atmosphere system, as recorded in both marine carbonate/organic matter and terrestrial organic material. The end-Permian extinction is the most severe biotic crisis in the fossil record. Its occurrence has been attributed to increased CO 2 levels deriving from massive Siberian volcanism.
