Triassic paleogeography — Triassic Period Distribution of landmasses, mountainous regions, shallow seas, and deep ocean basins during the early Triassic Period. Included in the paleogeographic reconstruction are the locations of the interval's subduction zones.

During the Late Triassic, evidence of humid climates is primarily indicated by the presence of coal deposits, which signify high rainfall and the formation of large swamps. These humid conditions were prevalent in high latitudes, as evidenced by coal occurrences in Triassic formations across the following regions:

Canada
Russia
Ukraine
China
Japan
South America
South Africa
Australia
Antarctica

Additionally, the transition to a more moist, monsoonal climate in the Late Triassic is supported by the presence of water-loving plants—such as ferns, horsetails, and lycopods—which extended as far north as 60° N latitude.12
