Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. de Bruijn et al. 1987 | rather large muroids. Endolophs of upper molars and ectolophids of lower molars almost entirely formed by the posterior arm of the protocone (id) and the anterior arm of the hypocone (id). The transverse ridges fot he oriinal cricetid dental pattern are suppressed and tend to be incorporated in, or replaced by, the ectolophs in the upper cheeck teeth and by the endolophids in the lower cheeck teeth. Wear facets, particularly in the M1 are developed on the steep faces of the cusps and in the valleys. The direction of the power stroke of the chewing movement makes an angle of about sixty degrees with the longitudinal axis of the teeth. | |
| H. de Bruijn and G. Saraç 1992 | Rather large muroids. The anterior outline of the anterocone of the M1 rounded. Anterior slope of the anterocone of unworn M1 with a norrow valley that reaches neither the tip nor the base of the anterocone. M1 wider over the protocone/paracone than over the hypocone/metacone. Protolophule of the M1 and M2 and hypolophid of the m1 and m2 constricted but usually complete in earlier species, strongly surpressed in the later ones. |
