Oreomylodon

Oreomylodon is an extinct genus of ground sloth in the family Mylodontidae, endemic to Ecuador during the Pleistocene. The only species, "O. wegneri", was long considered to be either a species or subgenus of "Glossotherium" (as "G. wegneri") or a junior synonym of "Glossotherium robustum", but studies of its cranial anatomy published in 2019 have supported "Oreomylodon" as a valid genus, and suggested it is more closely related to "Paramylodon". However, a subsequent analysis published in 2020 again sunk "Oreomylodon wegneri" into "Glossotherium," as a distinct species. It shows adaptations to living in a high-altitude habitat, and its fossils have frequently been unearthed in the Interandean Valles of Ecuador, at elevations of between 2,450 and 3,100 meters.
