D. Sigogneau-Russell 1983Dents trapues, tubercules b et c presque symétriques, l'un et l'autre bien sèparés de a; pas de "talon"; bourrelet lingual limité au bord postérieur; kühneocône très développé; surface d'usure de type Eozostrodon (? Morganucodon) engrènement des dents adjacents très lâche.
G. Hahn et al. 1991A genus of the Morganucodontidae, known only by isolated teeth, with the following characteristics of the lower molars: cusps band c are nearly of equal size and distinctly separated from the main cusp a. Internal cingulum consisting of isolated cusps, with well developed cusp g (kuehneocone) and cusp e. Talonid very short, with 3 cusps (d, bt 1, bt 2); cusp e not protruding anteriorly, hence week indentation between cusps e and b: the interlocking of adjacent teeth was loose. Enamel of the cusps more or less wrinkled. Occlusion of Morganucodon type, but different masticatory process.
