In fact, dinosaurs did not appear in the Permian period. Dinosaurs began to appear in the early Triassic period, about 230 million years ago. The Permian period was the heyday of the ancestors of dinosaurs, the archosaurs.

Some giant synapsid reptiles, such as the ancient creatures Sosaurus and Carthaginus, may be misunderstood as dinosaurs. But in fact, they do not belong to the classification level of dinosaurs, but are more closely related to mammals and reptiles.
