Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. Martin et al. 2010 | Differs from all other docodontans by a large pseudotalonid basin bordered by crests a–b, a–g, and b–g, crenulations on the distal side of the lower molar crowns, and an additional groove above the Meckelian groove separated from the more posterior trough for the postdentary bones (see description for details). Differs from Simpsonodon Kermack et al., 1987 by the structure of the mesial cingulid on the lower molars: in Dsungarodon it consists of two parts, a robust labial rim pointing mesiolingually and a weaker lingual rim extending to the base of cusp g; the two rims meet mesially at an acute angle. In Simpsonodon there is a continuous mesial cingulid wrapping around the mesial end of the crown between cusps b and g, with a rounded mesial end. Additionally, Dsungarodon has a somewhat more developed cusp dd compared to Simpsonodon. |
