Genera

This family is related to the other families of extinct ground sloths, Megatheriidae, Mylodontidae, Nothrotheriidae, and Scelidotheriidae. The only extant families of the suborder Folivora are Bradypodidae and Megalonychidae.

Taxonomy

The orophodontids constitute a rather small but quite distinct group. They are classified as a distinct mylodontan superfamily Orophodontoidea, the sister taxon to the Mylodontoidea. They were sloth-like but with bony armor.
