The Permian.
The Dimetrodon first appeared in the Paleozoic era, which held the 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.
No, as there was no Cretaceous-Permian extinction. There was the Permian-Triassic extinction, which ocurred before the dinosaurs appeared. Non-avian dinosaurs were wiped out in the Cretaceous-Paleogene extinction.
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 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 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 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 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.
The largest extinction event known is the Permian-Triassic Extinction Event, 250 million years ago. It is nicknamed "The Great Dying" in reference to how 96% of all known marine animals and 70% of all known terrestrial vertebrates at the time went extinct due to climatic changes because of volcanic eruptions and the formation of Pangaea.
