The ground sloth family [[Scelidotheriidae]] was demoted in 1995 to the subfamily Scelidotheriinae within Mylodontidae.<ref>{{cite web |url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=83047 |website=PaleoBiology Database |title=Scelidotheriinae, basic info}}</ref><ref name="Gaudin_1995">{{cite journal |last=Gaudin |first=T.J. |date=1995-09-14 |title=The Ear Region of Edentates and the Phylogeny of the Tardigrada (Mammalia, Xenarthra) |journal=Journal of Vertebrate Paleontology |volume=15 |issue=3 |pages=672–705 |doi=10.1080/02724634.1995.10011255 |jstor=4523658|bibcode=1995JVPal..15..672G }}<!--| access-date = 2013-06-19 --></ref> Based on collagen sequence data showing that its members are more distant from other mylodontids than [[Choloepodidae]], it was elevated back to full family status in 2019.<ref name="Presslee2019" /> Together with Mylodontidae, the enigmatic ''[[Pseudoprepotherium]]'' and [[two-toed sloth]]s, the scelidotheriids form the superfamily Mylodontoidea. ''[[Chubutherium]]'' is an ancestral and very plesiomorphic member of this subfamily and does not belong to the main group of closely related genera, which include ''[[Scelidotherium]]'' and ''[[Catonyx]]''.
