Abstract：An extreme greenhouse interval existed in the Norian of Late Triassic,lasted from the Middle Norian to the early Late Norian.The maximum sea surface temperature in low latitudes can reach 35 ℃ during the extremely high temperature interval occurred in the lower part of the conodont Mockina bidentata Zone.The extreme greenhouse interval of the Norian was accompanied by important biological evolution events in the ocean and land.The changes of dry and wet climate were not completely consistent in different regions.Many events occurred in this interval,such as global plate movement,igneous province activity,bolide and significant changes of geochemical indexes.The global significance of these events,their potential causality,and the response in the East Tethys need to be further studied.China has a good Norian stratigraphic sequence,which is an ideal area to study the climate change and biological evolution of this extreme greenhouse interval in the East Tethys region.
