Xenarthran is a sort of amardillo
An armadillo isn't a reptile, even though it has a shell. The scientific name, however, is Dasypodidan. The word Xenarthran reffers to armadillos, anteaters, sloths, and pangolins.Cingulata
Like all other xenarthran lineages, armadillos originated in South America. Due to the continent's former isolation, they were confined there for most of the Cenozoic.
Armadillos are native to the Americas, particularly Central and South America. They are concentrated most heavily around Paraguay. there are around twenty species of armadillo, and different species range as far north as the southern US (where they are also beginning to populate further north).
