D. Sigogneau-Russell 1995Last molar with high and narrow crown, with cusps a, c, d, decreasing regularly in height posteriorly; differs from all Triconodonta except Morganucodontidae by cusp b displaced lingually and included in the cingulum; differs from all Triconodonta by anterior notch displaced labially with presence of a cuspule f, a cuspule not present in any other Triconodonta.
G. V. R. Prasad and B. K. Manhas 2002Lower molars with high and narrow crown and a cusp formula of a > c > d > b; cusps a, c, d decreasing regularly in height posteriorly; the posterior crests of a and c are slightly longer than the anterior ones; cusps a and c with swollen labial bases; b as a small cusp; differs from all known triconodonts in the cusp formula; differs from all triconodonts except Gobiconodon Trofimov, 1978 and Dinnetherium Jenkins, Crompton & Downs, 1983 in the presence of anterior notch between e and f; differs from all triconodonts with the exception of Morganucodon Kühne, 1949 in having a very small cusp b.
