What dinosaurs were there in the Permian period?

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.

In the Permian period, animals on land included the ancestors of mammals, lizards, and reptiles. 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.
