Etymology
editThe genus is named Riostegotherium after Rio, of Rio de Janeiro, in reference to the state where the specimens were found; stego (Latin), meaning "covering"; therium (a Latinized Greek word), meaning "beast", a commonly-used suffix for mammalian genera.[2]
Description
editIt is known from fossil of armoured ossicles which are similar to the ossicles of the armour of modern armadillos that is obvious that in South American as far back as the late Paleocene armoured armadillos existed. Leg bones found in the area of probably came from Riostegotherium as well.[citation needed]
