 Details of "Glossotherium"’s diet are unclear since no dung deposits are available for analysis.However, based on dental evidence, "Glossotherium" was likely more suited to grazing, though it was also probably less efficient at ingesting grasses since its dental apparatus was more suited to shearing, which would have been too ineffective at processing plant materials down to an ingestible size to obtain adequate nutritive value.More recent tree sloths have a very slow rate of passage of food through the gut and it is likely that "Glossotherium" did as well.
