"(2017), however this resulted in similarly unclear results, and only showed weak affinities to the basal pseudosuchian Ornithosuchidae in the former and surprisingly to the non-archosaur archosauromorph Proterochampsia in the latter.Indeed, even after the trees were modified by removing unstable taxa, "Aenigmaspina" remained paired with the proterochampsian "Rhadinosuchus" despite being removed from all other proterochampsians and allied with Ornithosuchidae (shown in the cladogram below).
