  • C. ferelloii

Chubutherium ferelloii is an extinct species of ground sloth (Cattoi, 1962).

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. It is related to the Pleistocene genus, Scelidotherium. It possessed but a few molars, like many other sloths. Only a few specimens have been found in Patagonia.
