Mylodonopsis

Mylodonopsis is an extinct genus of ground sloth, containing a single species, Mylodonopsis ibseni from the Late Pleistocene of Brazil. It is a member of the family Mylodontidae. Although only known from fragmentary fossil remains, it has been proposed to be closely related to Mylodon.

Palaeobiology
It is suggested to have been a mixed feeder, being capable of both browsing and grazing. Two M. ibseni haemal arches and a caudal vertebra recovered from Gruta dos Brejões show evidence of palaeopathologies in the form of eroded articular surfaces.
