The Triassic period was significantly shaped by the events of the Permian period, particularly the Permian-Triassic extinction event, which occurred around 252 million years ago. This catastrophic event led to the loss of approximately 90-96% of marine species and around 70% of terrestrial vertebrates, drastically altering ecosystems. The aftermath of this mass extinction created ecological opportunities for the rise of new groups of organisms, including early dinosaurs and mammals, during the Triassic. Additionally, the climate and geological changes initiated in the Permian continued to influence conditions in the Triassic, fostering a period of recovery and diversification.

The Permian Period was ended by the Permian/Triassic Extinction Event, which wiped out 90% of the species on Earth at that time.
The Dimetrodon first appeared in the Paleozoic era, which held the Permian period.
The worst known mass extinction in Earth's history was the Permian-Triassic Extinction Event at the end of the Permian period. The Permian period was the last period of the Paleozoic Era.
The Triassic was from about 225 million to 190 million years ago. It is the first period of the Mesozoic ("middle life") Era.The Triassic Period is most commonly believed to have begun 251 million years ago and lasted until 199.6 million years ago.
The Triassic period lasted for approximately 51 million years, beginning around 252 million years ago and ending about 201 million years ago. It is the first period of the Mesozoic Era, following the Permian period and preceding the Jurassic period. The Triassic is characterized by the emergence of dinosaurs and the diversification of various life forms after the Permian-Triassic extinction event.
The period of Earth's history that lasted 245 to 208 million years ago is the Triassic period. This period followed the Permian period and preceded the Jurassic period. It was a time of recovery and diversification of life after the mass extinction at the end of the Permian period.
The Permian was the last period of the Paleozoic Era, spanning 299-351 million years ago. It was a time during which reptiles diversified. It ended with the Permian-Triassic extinction event, the largest mass extinction in Earth's history.
The correct order from oldest to most recent is Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, and Cretaceous. The Cambrian period marks the beginning of the Paleozoic Era, while the Cretaceous period is the last of the Mesozoic Era. The Permian and Triassic periods follow the Paleozoic and precede the Mesozoic, with the Jurassic and Cretaceous periods occurring afterward.
The Permian- Triassic extinction event was the greatest extinction on Earth. 95% of all organisms died during this time period, signaling the beginning of the Triassic.
