The continents of the end-Permian and early Triassic were more clustered in the tropics than they are now, and large tropical rivers would have dumped sediment into smaller, partially enclosed ocean basins at low latitudes.
Os continentes do final do Permiano e Triásico temperán estaban máis agrupados nos trópicos do que están agora, e grandes ríos tropicais terían vertido sedimentos en cuncas oceánicas pequenas parcialmente pechadas en latitudes baixas.
