Permian-Triassic paleoceanography

摘要

This theme issue of Global and Planetary Change is devoted to studies of "Permian-Triassic paleoceanography." It consists of 14 papers that advance our understanding of marine environmental conditions during the Permian-Triassic boundary (PTB) crisis and its aftermath (Table 1). The end-Permian mass extinction (EPME) at 252.28 Ma (Shen et al., 2011) was the largest biotic catastrophe of the Phanerozoic, resulting in the disappearance of～90% of skeletonized marine species (Erwin, 1994; Bambach et al., 2004; Alroy et al., 2008; Clapham et al., 2009) and a transition from the 'Paleozoic Fauna' to the 'Modern Fauna' (Sepkoski, 1982,2002).
