The Triassic began in the wake of Permian-Triassic extinction event, which left the Earth’s biosphere impoverished. Life did not recover until the middle of this period.
The supercontinent of Pangea, mostly assembled by the Triassic, allowed land animals to migrate from the South Pole to the North Pole, and warm-water faunas spread across the Tethys Sea.
