Genus Denisodon gen. nov.

Derivation of name: After Dr. Denise Sigogneau−Russell, Paris, in honour of her contributions to our knowledge of Mesozoic mammals.

Type species (monotypy): Denisodon moroccensis sp. nov.

Distribution.—Early Cretaceous (?Berriasian) of Morocco.

Diagnosis.—A genus of the Hahnodontidae with the following characteristics: Posterolingual cusp (l3) of m2small.

Posterobuccal cusps (b?2, b?3) rudimentary. Lingual wall of crown only slightly indented.

Discussion.— Denisodon differs from Hahnodon by its more reduced posterolingual cusp, but better preserved posterobuccal cusps. Moreover the indentation of the lingual wall of the crown is missing. With that, Denisodon looks somewhat more primitive than Hahnodon . In comparison with the Paulchoffatiidae , Denisodon is similar to Plesiochoffatia (see Hahn and Hahn 1998: fig. 39e), where the posterolingual cusp is completely reduced.
