The Early Oligocene was characterized by rapid global cooling and had profound impacts on global biosphere.Plant fossils from the Early Oligocene sediments can be used to explore the contemporary climatical features.By applying the coexistence approach to macrofossil and palynological data from the Shinao Formation in Panzhou district,Guizhou,this paper reconstructs quantitatively the Early Oligocene climate. Plant macrofossils indicate a warm and humid subtropical climate with MAT(mean annual temperature) of 15.7-21.9℃,CMMT (coldest month mean temperature)of 2.5-16.7℃,WMMT(warmest month mean temperature)of 21.6-28.1℃,MAP(mean annual precipitation)of 828.0-1 900.0mm, MPwet(mean precipitation of the wettest month)of 160.0-343.0mm,MPdry(mean precipitation of the driest month)of 7.0-54.0mm,MPwarm(mean precipitation of the warmest month)of 105.0-180.0 mm.Palynological fossils also suggest a warm and humid subtropical climate with MAT of 11.5-23.9℃, CMMT of-1.0-16.7℃,WMMT of 23.0-27.9℃,MAP of 803.0-1 613.0mm,MPwet of 116.0- 293.0mm,MPdry of 17.0-55.0mm,MPwarm of 94.0-180.0mm.The results suggest that the Early Oligocene climate of Panzhou district was a warm and humid subtropical,showing an evident seasonality indicated by hot and humid summers,which is similar to that of the present-day regions in southeastern China.The Early Oligocene floras from China indicate that the latitudinal gradients of climate showed a low meridional difference and were more equable in distribution than those of today.
