A relatively small ground sloth when compared to others such as Megatherium, Eremotherium and Glossotherium, Nothrotheriops seems to have had a similar lifestyle and dietary preference of browsing upon vegetation. One specimen of Nothrotheriops from Aden Crater in New Mexico was found in a lava tube and still had the remnants of hair and even a tendon still preserved. The best known species of Nothrotheriops is N. shastensis which is also known as the ‘Shasta ground sloth’ (after Shasta County, California).
