Samples collected from the Wayao Formation, which yields the Guanling Fauna, and the underling formation, the Zhuganpo Formation, were treated for conodont analysis. The study result shows that two conodont zones, Paragondolella polygnathiformis-P.tadpole Assemblage Zone and the P. polygnathiformis Zone can be recognized. Comparing with the international and domestic related information, a conclusion can be drawn that their epoch should belong to the Middle or Late Carnian of the Late Triassic. So the final result indicates that the age of the Guanling Fauna belong to the middle Carnian of the Late Triassic, maybe the late Carnian, not to the Ladinian of the Middle Triassic.
