(I'm not kidding)
The dicynodont was another Triassic animal, also known in other geologic eras.
(it goes PERMAIN -> MESOZOIC (Parts 123: Triassic -> Jurassic -> Cretaceous) -> CENOZOIC)

These are hardy fellows, having as a group survived the Permian-Triassic Extinction event, the Jurassic Ecologic Chaos, and the competition with the well-adapted dinosaurs. Their heyday was apparently in the early and middle Triassic, however, when they were as numerous as perhaps 95% of all land animals.

Among other things, the dicynodonts are amazing as a survivor from the early Triassic to the early Cretaceous. They were once though to have all died out in the Triassic for various reasons.
