It's in every dinosaur toy set, but it's NOT a dinosaur. Meet Dimetrodon, the apex predator that lived 40 million years before the first dinosaurs. That iconic sail? Likely a solar panel & status symbol for regulating body temperature and showing off. It's actually a "stem-mammal," a distant but important relative on our own evolutionary family tree. 🦴⚡ Retweet to confuse a friend: "Your favorite dinosaur is a proto-mammal." | Peter Dinolandia

Poor Dimetrodon. Commonly misidentified as a “dinosaur”. Did you know that Dimetrodon is more closely related to you (humans) than it is to dinosaurs? Dimetrodon is like the ultimate dino imposter, being the non-dinosaur ‘dinosaur’ posterchild of palaeontology. Dimetrodon is not even a reptile! It’s actually a protomammal that is more closely related to mammals than reptiles. A distant relative, as it were. Let that sink in. | Dr Dean Lomax - Palaeontologist

Field Museum on Instagram: "Not actually a dinosaur. 🦕❌ Despite what the silver screen and the toy aisle tell you, Dimetrodon was NOT a dinosaur. In fact, it’s more closely related to YOU than SUE the T.rex. 🦖 Dimetrodon is a non-mammalian synapsid that lived 280 to 265 million years ago, about 25 million years before dinosaurs appeared. 🕰️ While Dimetrodon *does* share a common relative with dinosaurs, it’s a distant one that lived 315 - 330 million years ago. 🗓️"
