Hahnodontidae is a family of extinct mammals from Early Cretaceous deposits in Morocco and the Western US. Although originally considered to belong to the extinct clade Multituberculata, recent work indicates that hahnodontids belong to the more primitive clade Haramiyida.
Temporal range: 145–120 Ma
Sigogneau-Russell (1991) and Hahn & Hahn (2003) classified hahnodontids as multituberculates, but the cladistic analysis of Cifelliodon recovered them outside Multituberculata as phylogenetically intermediate between Docodonta and crown Mammalia. The gondwanathere Vintana was also recovered as sister to members of Hahnodontidae.
