  • C. ferelloii

Chubutherium is an extinct genus of ground sloth described by Cattoi in 1962. The type species is C. ferelloii.


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.[citation needed] 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. Little material is found of the genus and the taxonomic position is still debated.[1]
