In particular, the Qingyan fauna in Middle Triassic shows biota radiation. The stratigraphical sequence has been studied extensively for a better understanding of the course and pattern of the biotic recovery and radiation following the End-Permian mass extinction. Five conodont zones, including Neospathodus dieneri zone, Neospathodus waageni zone, Neospathodus pingdingshanensis zone, Neospathodus homeri zone, and Chiosella timorensis zone, 2 foraminifer assemblages and 6 bivalve assemblages are recognized.
