Abstract. The end-Permian mass extinction horizon is marked by an abrupt shift in style of carbonate sedimentation and a negative excursion in the carbon isotope ( δ13 C) composition of carbonate minerals. Several extinction scenarios consistent with these observations have been put forward. Secular variation in the calcium isotope ( δ44/40 ...Sep 6, 2022 · 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.
