In the Late Permian and Early Triassic a well-pronounced climatic zonation took place that had an effect on the palaeozoogeographical division of sea basins into districts. Tethys and many seas of the Pacific ocean (Southern Primorye region, Little Khingan, Southern China, and Western USA region) were situated within tropical and subtropical zones (Tethyan Palaeozoogeographical Belt). In the Early Triassic Verkhoyanye region, Kolyma, Arctic Siberia, Spitsbergen, Arctic Canada and a part of Greenland and British Columbia were undoubtedly placed within the limits of the outtropical region of the northern hemisphere (Boreal Belt). Information about the location of the southern hemisphere outtropical region in the Permian and Triassic is very limited and needs more precise definition.
