These extinct mammals with spectacular horns were herbivores that lived in areas of tropical rainforests and mangrove swamps of northern Africa during the late Eocene and the early Oligocene from 36 to 30 million years ago. The Permian–Triassic extinction event, which was a prolonged event due to the accumulation of several extinction pulses, ended the dominance of carnivorous therapsids. [26] In the early Triassic, most medium to large land carnivore niches were taken over by archosaurs [27] which, over an extended period of time (35 million years), came to include the crocodylomorphs, [28] the pterosaurs and the dinosaurs; [29] however, large cynodonts like Trucidocynodon and traversodontids still occupied large sized carnivorous and herbivorous niches respectively.
