The analysis found eutriconodonts to be more closely related to therian mammals than monotremes were, but more distantly than (paraphyletic) amphitheriids, dryolestids, spalacotheriid "symmetrodonts" and multituberculates were.
Kuehneotherium praecursoris, classed as the most primitive therian mammal known, by contrast, could only manage 'soft' insects such as moths.
