Triassic period

Intro The Triassic period, spanning from 252 to 201 million years ago, marks the beginning of the Mesozoic Era and is characterized by the emergence of the first dinosaurs, while also being bookended by major extinction events, most notably the Permian-Triassic extinction which preceded it, leaving a largely depleted Earth's biosphere that slowly recovered throughout the Triassic period; during this time, the supercontinent Pangaea existed, leading to a mostly hot and dry climate with diverse reptile populations, including mammal-like reptiles that gradually gave way to the dominance of archosaurs, which included the early dinosaurs that first appeared in the late Triassic.
