Mylodontidae

Mylodontidae is a family of extinct mammals within the order of Pilosa and suborder Folivora living from approximately 23 mya—11,000 years ago, existing for approximately 22.89 million years. This family of ground sloths is related to the other families of extinct ground sloths, Megatheriidae and Nothrotheriidae. The only extant families of the suborder Folivora are Bradypodidae and Megalonychidae (the latter has extinct terrestrial species as well as extant arboreal species). Phylogenetic analyses using homologous sequences from all extant edentate groups indicates that Mylodontidae was more closely related to Megalonychidae than to Bradypodidae.
