The Permian (along with the Paleozoic) ended with the Permian–Triassic extinction event (colloquially known as the Great Dying), the largest mass extinction in Earth's history (which is the last of the three or four crises that occurred in the Permian), in which nearly 81% of marine species and 70% of terrestrial species died out, associated ...
Permian–Triassic boundary at Frazer Beach in New South Wales, with the End Permian extinction event located just above the coal layer [2]. Approximately 251.9 million years ago, the Permian–Triassic (P–T, P–Tr) extinction event (PTME; also known as the Late Permian extinction event, [3] the Latest Permian extinction event, [4] the End-Permian extinction event, [5] [6] and colloquially ...

Permian: Permian–Triassic extinction event: 252 Ma Large igneous province (LIP) eruptions [23] from the Siberian Traps, [24] an impact event (the Wilkes Land Crater), [25] an Anoxic event, [26] an Ice age, [27] or other possible causes End-Capitanian extinction event: 260 Ma: Volcanism from the Emeishan Traps, [28] resulting in global cooling ...
The evolutionary precursors to mammals dominated the country until a mass extinction event ended their reign. The Triassic, the first period of the Mesozoic Era, followed. Dinosaurs evolved and began their rise to dominance, quickly spreading into the United States. Soon, Pangaea began to split up and North America began drifting north and ...
The era began in the wake of the Permian–Triassic extinction event, the largest mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, pterosaurs, mosasaurs, and plesiosaurs. The Mesozoic was a time of significant tectonic ...
The Permian ended about 252 million years ago with Earth's worst mass extinction. The first dinosaurs appeared roughly 230 million years ago during the Triassic Period.
