Analcitherium is an extinct genus of scelidotheriid sloth that lived during the Early Miocene in what is now Argentina. Fossils have been found in the Santa Cruz Formation of Argentina.[1]

Taxonomy

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,[2] 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.[3]

Below is a phylogenetic tree of the Mylodontidae, based on the work of Varela et al. 2018.[4]
