• However, this species was later reclassified in their own genus, " Pseudoprepotherium ", as a basal member of another family of ground sloths, the Mylodontidae.
• ""'Scelidotherium " "'is an extinct genus of ground sloth of the family Mylodontidae, endemic to South America during the middle Pleistocene epoch.
• This species of ground sloth, once assigned to the family Scelidotheriidae, is now assigned to subfamily Scelidotheriinae within Mylodontidae . " C . ferelloii " first appeared in the Oligocene and died out during the Middle Miocene.
• Together with the rest of Mylodontidae and the engimatic " Pseudoprepotherium ", the scelidotheriines form the superfamily Mylodontoidea . " Chubutherium " is an ancestral and very plesiomorphic member of this subfamily and does not belong to the main group of closely related genera.
