Nothrotherium is an extinct genus of medium-sized ground sloth from South America (Bolivia, Brazil and the Ware Formation, La Guajira, Colombia).[1] It differs from Nothrotheriops in smaller size and differences in skull and hind leg bones, but both genera can be traced back to Hapalops, the genus which both evolved from in different ecological conditions.[2] This genus formerly included the species Nothrotheriops shastensis, which was later moved to Nothrotheriops. These browsing ground sloths consumed roots, stems, seeds, and leaves of various desert plants, such as the yucca and agave.[3]

The species N. maquinense is named after the Maquiné Grotto in Brazil, where it was found.

Synonyms such as Coelodon occasionally cause confusion where they occur in early texts such as that of Alfred Russel Wallace's major work, "The Geographical Distribution of Animals".[4]
