Relation to other taxa
Currently, Quercygale is either assigned to no family (i. e. it is just classified as one of the basal genera of Carnivoraformes) or it is assigned to the paraphyletic family Miacidae.[9] Phylogenetic analysis of the basicranial morphology of carnivoramorphans suggests that Quercygale is the most advanced member of the clade Carnivoraformes as a sister taxon to crown-clade Carnivora, predating the split between Feliformia and Caniformia.[10][11][12] Another recent study, however, has proposed that the genus Quercygale should be placed as a stem group within Feliformia.[13]
In the past (till about 2010), Quercygale was assigned either to the family Miacidae (which was considered monophyletic in the past), or to the family Viverravidae. Only one author (Kretzoi 1945) classified it as the only genus of its own family Quercygalidae (Quercygalidae, however, was considered another name for the family Miacidae by another author). Alternatively, individual authors considered Quercygale to be a basal genus of Caniformia or a synonym of the genus Tapocyon.[10][14][15]
