Hahnodon ("Hahn's tooth") is an extinct genus of mammaliaforms from the Early Cretaceous Ksar Metlili Formation in Morocco. Although originally considered to be a relatively early member of the extinct clade Multituberculata, recent studies indicate that it instead is a haramiyid.

Fossils and distribution

Hahnodon taqueti is based on a single lower molar found in Lower Cretaceous strata in Morocco.


Denise Sigogneau-Russell (1991) classified Hahnodon as a member of Multituberculata, but others later considered it to be related to members of Haramiyida. The description of Cifelliodon from North America confirmed that Hahnodon — and by extension, Hahnodontidae — belong to Haramiyida.
