The greater fairy armadillo (Calyptophractus retusus), also known as Burmeister's armadillo or the Chacoan fairy armadillo, is a species of armadillo in the family Chlamyphoridae. It is found in Argentina, Bolivia, and Paraguay. Its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland. It is threatened by habitat loss. It is the only species in the genus Calyptophractus.
The greater fairy armadillo is a small species, growing to a length of from 140 to 175 millimetres (5.5 to 6.9 in) with a tail about 35 millimetres (1.4 in) long and weighing up to a kilogram (2.2 lb). Like other armadillos it has bands of armour on its dorsal (upper) surface but, in common with the pink fairy armadillo Chlamyphorus truncatus but unlike most other armadillos, these bands are fused to its pelvis and spine. They are soft in texture and are linked together with skin which gives flexibility to the body. They come to an abrupt end at the rear of the body. The ventral surface is clad in dense, woolly hair and there are some sparse hairs on the dorsal surface as well. The forefeet are scoop-shaped and have curved claws, and the hind feet have sharp claws for burrowing.
The greater fairy armadillo is native to the Gran Chaco region of northern Argentina, central and south-eastern Bolivia and western Paraguay. It inhabits dry grassy areas and is found only in places with light sandy soils in which it can burrow.
The behaviour of the greater fairy armadillo has been little studied. It is an expert tunneller and spends most of its time in the shallow burrows that it excavates and is seldom seen above ground during the day. If disturbed, it can bury itself rapidly, and may block the entrance to its burrow with its hindermost plates. It has an omnivorous diet and feeds on worms, insect larvae, insects, snails, roots and seeds.
