Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. W. Krause and J. F. Bonaparte 1993 | Differs from Ferugliotheriidae in being much larger and in possessing large, hypsodont molars, each supported by a massive root covered with cement. Coronal pattern of ridges and furrows on molars is generally more complex than in Ferugliotheriidae. |
