This diet represents the culmination of a series of adaptations within Silesauridae, starting with carnivory in "Lewisuchus" (evidenced by recurved and finely serrated teeth), leading to omnivory and/or insectivory in "Asilisaurus" and "Silesaurus" (conical teeth with few serrations), and eventually the evolution of a specialized herbivorous diet in advanced sulcimentisaurians.
