Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. J. Goin et al. 2012 | Gondwanatheria differ from the Ferugliotheriidae in its much larger size, protohypsodont molariforms that have its transverse lobes better defined by deep, narrow grooves, and by its wear pattern, which is quite marked at the central portion of the molariforms all along its lengths. Gondwanatheria differs from all known Sudamericidae in having a much thinner enamel layer in its molariforms. It differs from South American Sudamericidae in its larger size and specifically from S. ameghinoi in the marked asymmetry of its upper molariform grooves (exclusively lingual in Greniodon, both labial and lingual in Sudamerica). Moreover, it differs from Madagascar and Indian Sudamericidae in its much larger size, thinner enamel layer, more complex occlusal design of its molariforms, absence of perikymata, and much deeper lingual grooves that divide the crown into several distinct lobes. |
