MINO-BOILINI, Ángel R.  y  QUINONES, Sofía I.. The sloths Scelidotheriinae (Xenarthra, Folivora): taxonomy, biocronology, and biogeog raphy. Rev. Mus. Argent. Cienc. Nat. [online]. 2020, vol.22, n.2, pp.201-218. ISSN 1853-0400.  http://dx.doi.org/10.22179/revmacn.22.681.

The sloths Scelidotheriinae (Mammalia, Xenarthra, Mylodontidae) represents a South American clade which did not participate in the Great American Biotic Interchange (GABI); however, they reached in this sub continent a wide geographic distribution. The objective of this contribution is to make taxonomical, chorologi cal, stratigraphic, and biogeographical considerations of the sloths Scelidotheriinae from the late Cenozoic with emphasis on the Argentinean records. The subfamily Scelidotheriinae is recorded during the middle Miocene to early Holocene in South America, more precisely in Argentina, Bolivia, Brazil, Colombia, Chile, Peru, Ecuador, Uruguay, and Paraguay.
