Description

This species of ground sloth was assigned to the family Scelidotheriidae, which was subsequently demoted to subfamily Scelidotheriinae within Mylodontidae, then elevated back to full family status.[1] 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. Little material is found of the genus and the taxonomic position is still debated.[2]
