It's hard to get any respect when you're a Permian synapsid. People tend to think of dinosaurs as the worlds most terrifying prehistoric beasts, but Anteosaurus was the real deal. The largest predator the Earth had ever seen to that point. Head to body size ration was crazy off kilter. Anteosaurus spent their days looking for snacks and tearing up the flood plains of what is now South Africa (Southern Pangaea). It took another 50 million years before anyone else came around that came close to this guys swagger.
