The origins of the order can be traced back as far as the early Tertiary (about 60 million years ago, shortly after the Mesozoic era ). The presence of these animals in North America is explained by the Great American Interchange It includes the anteaters sloths , and armadillos . In the past, these families were classified together with the pangolins and Aardvark as the order Edentata (meaning toothless, because the members do not have front incisor teeth or molars, or have poorly-developed molars). It was subsequently realized that Edentata was

   Extractions: THE ORDER XENARTHRA: Southern North America and South America is their distribution, and the Xenarthrans consist of 29 species in four distinct families: anteaters, sloths (two families - two and three-toed), and armadillos. Anteaters are toothless, sloths and armadillos lack incisors and canines but do have simple cheek teeth that lack enamel and grow continuously from the roots as the tops wear down. Armadillos have up to 100 such teeth. Their skulls are elongated and the brain small and narrow. But other similarities seem difficult to come by. How could three such different-looking types of animals be related? It is in the vertebrae of the lumbar region where they have an extra articulation. It is a skeletal feature peculiar to this order, and "Xenarthra" means "strange joints." Their specially strengthened backbone may have evolved from the defense posture that anteaters assume. If threatened, the animal stands erect on its hind legs and braces itself with its strong, heavy tail, forming a tripod. It then proceeds to lash out with its powerful arms, slashing with its formidable claws.

   Extractions: Anteaters, armadillos, and sloths are a group of eutherian mammals known as the Xenarthra. They were once placed in the order Edentata and are still often referred to as edentates , a word that means "toothless." Although xenarthrans such as anteaters are indeed toothless, the giant armadillo has as many as 100 teeth, more than almost any other mammal. Members of the mammalian group Edentata not only include the 31 living species of armadillos, true anteaters, and tree sloths, but also contain eight families of extinct ground sloths and armadillo-like animals. Together, the living families and extinct families constitute the Xenarthra. Xenarthrans are a small group of insectivores and herbivores of small to medium body size (up to around 60 kg). In the past however, xenarthrans were much more diverse and numerous. They radiated into about a dozen families in South America, including not only the groups known today but also animals such as the extinct giant ground sloths and giant armored gylptodonts. Several groups of xenarthrans, mainly the ground sloths and armadillos, successfully crossed the Central American land bridge to North America when it formed during the Pliocene . Today, only one of these species, an armadillo (

Its members are bizarre creatures and highly specialized in structure and habits. The toothless anteaters are provided with heavy claws to tear apart termite nests and a long, slender, protrusile, sticky tongue to capture the insects. The slow-moving, plant-eating sloths are tree dwellers, with a rudimentary tail and only two or three toes on each foot. In the large group of armadillos, the presence of a bony carapace is unique among mammals. The Order is divided into three families, all of which are restricted to Central and South America with the exception of one species, the nine-banded armadillo, which ranges north to the United States.

Sign Up Now! Description: Armadillos, sloths, and anteaters belong to the Order Xenarthra. Members of this group of mammals share the following characteristics: Xenarthrans comprise an ancient group of placental mammals that once roamed across Gondwanaland before the continents of the Southern Hemisphere separated into their present day configuration. Evolution: When Gondwanaland divided, it formed South America, Africa, India, Arabia, New Zealand, and Australia. At that time, xenarthrans were isolated on the continent of South America. Since then, they have been gradually spreading and now can be found in areas of Central America and southern parts of North America. Though xenarthran populations were absent from Africa, Asia, and Australia, these regions contain unrelated species that evolved to resemble xenarthrans. Similar environmental conditions in these distant parts of the world resulted in species that, although unrelated, adapted in a similar manner and as a result resemble each other in some ways. This evolutionary dynamic is known as convergent evolution.

    Extractions: This order of placental mammals contains approximately 30 species of anteaters, sloths and armadillos. They range from the Pink Fairy Armadillo that weighs 3 ounces to the 132 pound Giant Armadillo. Although the this order's previous Latin name, Edentadia signifies toothlessness, only the anteater actually lacks teeth. In fact the Giant Armadillo, with a total of 80 to 100 teeth, has more teeth then almost any other mammal. Armadillos lack incisors and canines.

    Extractions: Xenarthra Xenarthrans probably evolved in SouthAmerica, and this continent has been their traditional home, although some have migrated into North America. Although these creatures did not radiate into arboreal insectivore niches as in RL (these niches already having been taken by the didelphids), they became quite succsessful as insectivorous ground-dwellers and burrowers. INSECTIPHAGIDAE (Pangodilloes) Spec's 'ant-eaters' are the dominant small insectivores of South America, and are clearly xenarthrans, possessing the clade's slow-growing, enamel-less teeth and xenarthrual articulation between their vertebrae (although insectiphags' backs are more flexible than other xenarthrans. However, these hedge-hog like creatures are not true myrmecophagids (the famliar ant-eaters of our home timeline), but a more generalized family that often mimics the pholidotes (pangolins) of RL. The first mammalogists to explore Spec's Panamanian Isthmus were startled to discover the pangodillo ( Echinomanis echinis ) a creature that at first glance appeared to be a pangolin - a scaled anteater. Not only did the creature possess razor-sharp blade-like 'spikes' instead of the flat but very tough scales of the homeworld pangolins, its mere existence in the New World, and simply

    Extractions: Giant anteater Order Xenarthra: sloths, armadillos, and anteaters The old name for this order, Edentata (="toothless") has been replaced by the more appropriate term Xenarthra. Among living species, only the anteaters (superfamily Myrmecophagoidea) are toothless. All living species are New World mammals, the largest being the giant anteater Myrmecophaga tridactyla (shown at left), which reaches a length of 120 cm/3' 7" and a weight up to 40 kg/83 pounds. Xenarthra share the following characters: Females have a common urogenital duct; toes all strongly clawed; testes interior, between bladder and rectum; double posterior vena cava. Giant anteaters use a long, sticky tongue to capture the huge quantities of ants and termites. The huge front claws easily open concrete-hard termite mounds, and serve as effective weapons o self-defense.

13. ORDER XENARTHRA
    Armadillos are in the same order with anteaters and tree sloths (Edentata, or xenarthra). These three all came north over the Panama isthmus 3 million years  
    http://www.bobpickett.org/armadilloart.htm
    
    Extractions: ORDER XENARTHRA Family Dasypodidae - Armadillos Dasypus novemcinctus - Nine-banded Armadillo NATIONAL WILDLIFE (?) - Of 20 species of armadillos, only one (the nine-banded) is found in the US. Unlike any other mammal, it produces four genetically identical offspring at almost every birth. Additionally, it can delay implantation until suitable conditions exist. Armadillos are in the same order with anteaters and tree sloths ( Edentata , or Xenarthra ). These three all came north over the Panama isthmus 3 million years ago, with the latter two disappearing about the time Man made his impact in North America, or about 10,000 years ago. The armadillo was only known to exist in Central America until a colony made it as far north as Texas in 1850. Then, in the swiftest migration known in mammalian history, the nine-banded armadillo raced through the Gulf States toward the Atlantic, reaching Florida in the late 1970's. Now, 30 million live in the southern US. Crossing small rivers, the armadillo has the ability to either swim across, or actually walk across the bottom of the river, emerging up to five minutes later on the other side. Armadillos dig dens in the ground and surface in late afternoons to feed. They have keen smell, but poor eyesight. Only the nine-banded and a few South American species have the trait of quadruple identical pups from the same fertilized egg. This increases the rate of pop success, since only one ovum per year occur. Delayed implantation can be as long as two years (the fertilized egg develops into a multiple-celled blastocyst and floats free in the uterus until favorable conditions exist. Numerous animals, like bear and many members of the weasel family can delay implantation for several months, but nothing like this.)

The order takes its name from xenarthrous processes—extra pairs of joints in certain vertebrae, or spinal bones, found only in members of this order. This unique adaptation helps support the back during digging. Mammals in the Xenarthra order first appeared in South America during the Paleocene Epoch, about 65 million years ago. When a land bridge formed between North and South America in the Pliocene Epoch, roughly 5 million years ago, members of this order crossed to North America. Today these mammals can be found in Central and South America and the southern central and southeastern areas of North America. Apart from xenarthrous processes, armadillos, anteaters, and sloths have few similarities. All three have a good sense of smell, but anteaters have poor eyesight, whereas sloths and armadillos have relatively good vision. Armadillos also have a keen sense of hearing, while anteaters and sloths have poor hearing. Anteaters are known for their tubular snout and long tongue, which they use to eat ants and termites; armadillos eat insects, small vertebrates, and plants; and sloths eat only plants. Armadillos are ground dwellers and are active during the day or night. Most anteaters and all sloths live in trees and are active primarily at night.

    Extractions: Including anteaters, armadillos and sloths. They were formerly classified as the order Edentata (meaning toothless) and put in the same order as the aardvark and pangolin s, until they discovered that the order was polyphyletic , meaning that unrelated species were seen as a group and was invalid. Now, anteaters, armadillos and sloths are in the order called Xenarthra which means "strange joints". It was named this way because they all have unique vertebral joint structure unlike any other mammal. The smallest member of the Xenarthra is the Silky anteater , the largest is the Giant anteater Image: photographer Malene Thyssen , Licensed under Attribution ShareAlike 2.5
