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, being the Megatheriidae, the Nothrotheriidae, the Orophodontidae and the Scelidotheriidae. The only extant families of the suborder Folivora are the Bradypodidae and the Megalonychidae. Phylogenetic analyses using homologous sequences from all extant edentate groups indicates that the Mylodontidae were closer related to Megalonychidae than to Bradypodidae.
