Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| K. Matsui and T. Tsuihiji 2019 | The clade consisting of Paleoparadoxiinae + Desmostylidae was supported by the absence of the p3 paraconid (c. 12(1)), fused double roots of p3 and p4 (c. 14(2)), swollen and appressed molar cusps (c. 17(1)), enlarged P4-M3 hypoconulid and entoconid (c. 18(1)) and having osteosclerosis bones of vertebrae (centrum) (c. 75(1)). |
