Analcitherium was first named by
Florentino Ameghino in 1891 based on fossils found in Argentina, dating to the Early Miocene. Originally thought to belong to a juvenile
Nematherium. It is now usually considered to be a distinct genus.
Analcitherium is a member of the Scelidotheriidae, a group of terrestrial sloths known from the Oligocene and Pleistocene that a characterized by an elongated snout. Although scelidotheriids are usually placed as a subfamily of the
Mylodontidae, they are sometimes considered to be a separate family,
Scelidotheriidae. Below is a phylogenetic tree of the Mylodontidae, based on the work of Varela
et al. 2018. == References ==
