Gorgonopsid: 265 - 252 mya. These were saber-toothed carnivores that existed about 7 million years after Dimetrodon, and were some of the largest predators to dominate the Late Permian. They also had saber teeth before Smilodon made them fashionable - preceding those cool cats by a smooth 250 million years. (at The Field Museum)
