The genus includes some of the largest and smallest known astrapotherian, but at present no generally recognized description can adequately characterize it.[1] DescriptionThe genus was first described by {{Harvnb|Ameghino|1895}}. He distinguished it from the Santacrucian (late Early Miocene) Astrapotherium ({{Harvnb|Burmeister|1879}}) based on the greater number of upper and lower molars. Although later researchers disagreed and concluded that Ameghino based his conclusion on very fragmentary materials, they mostly agreed to distinguish the genus from other groups of astrapotherians.[1] {{clearleft}}SpeciesThe following species have been recognised:[3]
