Nothrotherium

Nothrotherium is an extinct genus of medium-sized ground sloth from South America (Bolivia, Brazil and the Ware Formation, La Guajira, Colombia). It differs from Nothrotheriops in smaller size and differences in skull and hind leg bones.

==Taxonomy== Nothrotherium is derived from the Greek nothros [νωθρός], meaning "lazy" or "slothful," and therion [θηρίον], "beast", and the type 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 (1876). This genus formerly included the species Nothrotheriops shastensis, which was later moved to Nothrotheriops.
