The Triassic is a geologic period of the Mesozoic Era spanning approximately 252 to 201 million years ago, immediately following the Permian–Triassic mass extinction and preceding the Jurassic. It is subdivided into Early, Middle, and Late Triassic epochs, characterized by the breakup initiation of the supercontinent Pangea, widespread arid continental climates, and the recovery and diversification of life. The Triassic marks the early radiation of dinosaurs, pterosaurs, and marine reptiles, as well as the emergence of modern-style coral reefs and key evolutionary lineages among ammonoids and early mammals, setting the biotic framework for subsequent Mesozoic ecosystems.
Mass extinctions are extremely catastrophic events on Earth. Throughout Earth's evolutionary history, numerous mass extinctions have occurred, with five major mass extinctions being particularly representative. These extinctions ...
