'''''Hahnodon''''' ("Hahn's tooth") is an [[extinct]] [[genus]] of [[mammaliaform]]s 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 [[Haramiyida|haramiyid]].<ref>{{Cite web|url=https://www.natureasia.com/en/research/highlight/12522/|title=Fossils: Youngest known haramiyid fossil found in North America &#124; Nature &#124; Nature Portfolio|access-date=2018-05-26|archive-date=2022-05-17|archive-url=https://web.archive.org/web/20220517105652/http://www.natureasia.com/en/research/highlight/12522|url-status=dead}}</ref><br />

==Fossils and distribution==<br />
''Hahnodon taqueti'' is based on a single lower molar found in Lower Cretaceous [[stratum|strata]] in [[Morocco]].<br />
<br />
==Classification==<br />
[[Denise Sigogneau-Russell]] (1991) classified ''Hahnodon'' as a member of Multituberculata, but others later considered it to be related to members of Haramiyida.<ref>Butler, P. M., & Hooker, J. J.
