摘　　要：According to the recent global mean surface temperature curve[1],the temperature continued to rise over a period of 45 million years at the end of the Paleozoic.The global mean temperature increased from 11.7°C at 295 Ma at the beginning of the Permian to 32.7°C at 250 Ma at the beginning of the Triassic,a warming of21°C,one of the most dramatic warmings in the Phanerozoic(Fig.1a),which is referred to in this paper as the end-Paleozoic great warming(EPGW).Another significant warming event occurred in the mid-Cretaceous,when the global average temperature rose by 8.8 C in 8 million years,reaching 28.2°C.
