Genus Hahnotherium nov.

Type species: Hahnotherium antiquum sp. nov.

Derivation of name: Named in honour of Professor Gerhard Hahn, whose work laid the foundation for our knowledge of early multituberculates. Also from θεριον (Greek), wild beast. Neuter.

Diagnosis.—With the characters of the family, by monotypy.

Comment.—This genus is proposed for the two most multituberculate−like molars described by Kermack et al. (1998). They identified M46797 as a left lower molar (group ζ); it is interpreted here as a left second upper molar, and made the holotype of a new genus and species. The second specimen, M46763, also previously regarded as a left lower molar (group Υ), is interpreted here as a right second lower molar, and tentatively referred to the same species. M46183, also included in group Υ, has been interpreted in this paper as a posterior lower molar of Millsodon superstes .
