permian period
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 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 period was a geologic period that occurred from about 299 to 251 million years ago. It is known for its diverse flora and fauna, including the dominant reptiles that laid the foundation for modern ecosystems. The end of the Permian period marked the largest mass extinction event in Earth's history, known as the Permian-Triassic extinction.
The Triassic Period is a geological time period that occurred from about 251 to 201 million years ago. It followed the Permian Period and preceded the Jurassic Period in the Mesozoic Era. The Triassic Period saw the diversification of early reptiles and the rise of dinosaurs.
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.
