(Early Permian, around 295–272 mya)
Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it went extinct around 40 million years before the appearance of the first dinosaur in the Triassic period. Generally reptile-like in appearance and physiology, Dimetrodon is nevertheless more closely related to mammals than it is to any living reptilian group, though it is not a direct ancestor of any mammals.
Dimetrodon belongs to a group traditionally called "mammal-like reptiles", more recently termed "stem-mammals" or "non-mammalian synapsids" because many vertebrate paleontologists today group Dimetrodon together with mammals in an evolutionary group or clade called Synapsida, while dinosaurs go together with living reptiles and birds in a separate group, Sauropsida.
