haramiyidans are a long lived lineage of mammaliaform cynodonts or mammals. their teeth, which are by far the most common remains, resemble those of the multituberculates. however, based on "haramiyavia", the jaw is less derived; and at the level of evolution of earlier basal mammals like "morganucodon" and "kuehneotherium", with a groove for ear ossicles on the dentary. if they are early multituberculates, they would be the longest lived mammalian clade of all time. however, a more recent study, in november 2015, may dispute this and suggested the haramiyida were not crown mammals, but were part of an earlier offshoot of mammaliaformes instead.
