It is proposed that oscillating temperature conditions in the late Wuchiapingian and early Changhsingian (Late Permian) followed in the Boreal Superrealm to less variable climatic conditions in the late Changhsingian and early Induan (the time of trap formation of the Siberian Platform), with stable trend of increasing temperature in the Early Triassic. The Problem of the absence of signs of mass extinction of marine organisms at the Permian-Triassic boundary in the Boreal Superrealm is discussed.
