Xenarthra
Xenarthra (; from Ancient Greek ξένος, xénos, "foreign, alien" + ἄρθρον, árthron, "joint") is a major clade of placental mammals native to the Americas. There are 31 living species: the anteaters, tree sloths, and armadillos. Extinct xenarthrans include the glyptodonts, pampatheres and ground sloths. Xenarthrans originated in South America during the late Paleocene about 60 million years ago. They evolved and diversified extensively in South America during the continent's long period of isolation in the early to mid Cenozoic Era. They spread to the Antilles by the early Miocene and, starting about 3 Mya, spread to Central and North America as part of the Great American Interchange. Nearly all of the formerly abundant megafaunal xenarthrans became extinct at the end of the Pleistocene.

xenarthra
Xenarthra is a superorder of placental mammals found in the Americas that includes armadillos, anteaters, and sloths. The name Xenarthra means "strange joints", referring to the unique joints in their vertebral columns. They are characterized by several unique features including the reduction or loss of teeth, and the development of a special articulation between the lumbar vertebrae and the sacrum.

Xenarthra
The superorder Xenarthra is a group of placental mammals, extant today only in the Americas and represented by anteaters, tree sloths, and armadillos. The origins of the order can be traced as far back as the Paleogene in South America. Xenarthrans developed and diversified extensively in South America during its long period of isolation. They invaded the Antilles by the early Miocene and, starting about nine million years ago, they spread to Central and North America as part of the Great American Interchange. Nearly all of the formerly abundant megafaunal xenarthrans, such as ground sloths, glyptodonts and pampatheres, went extinct at the end of the Pleistocene. Xenarthrans share several characteristics that are not present in other placental mammals. The name Xenarthra, which means "strange joints", was chosen because their vertebral joints have extra articulations and are unlike those of any other mammals — a character referred to as "xenarthry" — and ischiosacral fusion. The males have internal testicles, which are located between the bladder and the rectum. Also, xenarthrans have the lowest metabolic rates among the therians.

Xenarthra
An order of New World mammals characterized by the absence of incisors and canines from among their teeth, and comprising the ARMADILLOS, the SLOTHS, and the anteaters. The order is distinguished from all others by what are known as xenarthrous vertebrae (xenos, strange; arthron, joint): there are secondary, and sometimes even more, articulations between the vertebrae of the lumbar series. The order was formerly called Edentata. (From Random House Unabridged Dictionary, 2d ed; Walker's Mammals of the World, 5th ed, vol. I, p515)
