Abstract  14 ichnogenera are reported in the Daye Formation of Early Triassic from Huaxi of Guiyang, Guizhou Province of South China. They include Beaconichnus、Cosmorhaphe、Dendrorhaphe、Gyrochorte、Gordia、Micatuba、Mammillichnis、Megagrapton、Planolites、Palaeophycus、Phycodes、Phycosiphon、Rhizocorallium and Undichna, and are characterized by the fodinichnia-dominant trace fossil assemblage、distribution of paralleling bed surface、shallow tireing and minimized Planolites. The features indicate that the shallow marine environment of South China in the Early Triassic was still stressful and anoxic. Such conditions didn’t change until the Late Early Triassic. The presence of trace fossils from the Member 1 to Member 3 in the Daye Formatin embodies the ecological succession of marine ecosystem. Trace makers develop their diversity from previously single polychaeta in the Member 1 to diversified polychaeta until the appearance of crustacean represented by Rhizocorallium-maker on top of the Member 3 of the Daye Formation. The developing model of soft-bodied organisms herein during the recovery interval after the end-Permian mass extinction is similar to that represented by the trace fossils during the recovery interval after the Devonian Frasnian-Famennian extinction in Dushan of Guizhou. A comparison of the appearance probability of complex trace fossils such as Rhizocorallium and Thalassinoides before and after the end Permian mass extinction globally reveals the soft-bodied organisms experienced a longer protracted biotic recovery in lower latitude regions than that in higher ones.
