Hahnodon

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.^[1]

Classification

Denise Sigogneau-Russell (1991) classified Hahnodon as a member of Multituberculata, but others later considered it to be related to members of Haramiyida.^[2][3] The description of Cifelliodon from North America confirmed that Hahnodon — and by extension, Hahnodontidae — belong to Haramiyida.^[4]
