Aulacephalodon

Dicynodon bainii

Aulacephalodon bainii roamed the floodplains of southern Pangaea as a barrel-chested, tusked herbivore well before the rise of dinosaurs. Heavy nasal bosses and deep skull arches supported a powerful keratinous beak capable of slicing tough, fibrous vegetation. Striking cranial differences in fossil skulls suggest pronounced sexual dimorphism, with mature individuals likely displaying enlarged facial bosses during territorial or courtship displays.
