University of Florida researcher. Determining whether the first arrival of humans or the warm-up of the American continent at the end of the last Ice Age was responsible for the demise of prehistoric sloths has puzzled scientists because both events occurred at the same time, about 11,000 years ago. But by using radiocarbon to date fossils from Cuba and Hispaniola, where humans appeared later than on the North American continent, long after the last Ice Age occurred, UF ornithologist David Steadman was able to separate the two events. He and his colleagues found the last record of West Indian ground sloths coincided with the arrival of humans 4,400 years ago. The results are published in a

For other uses, see Sloth (disambiguation) Sloths Brown-throated Three-toed Sloth Bradypus variegatus Lake Gatun Republic of Panama Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Subclass: Theria Infraclass: Eutheria Superorder: Xenarthra Order: Pilosa Suborder: Folivora Delsuc, Catzeflis, Stanhope, and Douzery, 2001 Families Bradypodidae Megalonychidae and see text The living sloths comprise 6 species of medium-sized mammals that live in Central and South America belonging to the families Megalonychidae and Bradypodidae , part of the order Pilosa . Most scientists call the sloth suborder Folivora , while some call it Phyllophaga . Both names mean "leaf-eaters"; the first is derived from Latin , the second from ancient Greek This article mainly deals with the living tree-dwelling sloths. Until geologically recent times, large ground sloths such as Megatherium lived in South America and parts of North America , but along with many other animals they disappeared immediately after the arrival of humans on the continent. Much evidence suggests that human hunting contributed to the extinction of the American megafauna , like that of far northern Asia Australia New Zealand , and Madagascar . Simultaneous climate change that came with the end of the last Ice Age may have also played a role in some cases. However, the fact that

San Francisco State University Department of Geography Geography 316: Biogeography The Biogeography of the Brown-throated Three-toed sloth (Bradypus variegatus) By: Christine Chan, student in Geography 316, Fall 1999 Kingdom: Animalia Phylum: Chordata Class: Mammalia Order : Endentata = Xenarthra or Suborder: Xenarthra Family: Bradypodidae Genus: Bradypus Species: Bradypus variegatus Description of Species The brown-throated three-toed sloth (Bradypus variegatus) can be identified and distinguished from other members of its genus by the brown color of its fur on the sides of its face and throat, prominent dark brown forehead, suborbital stripe outlining the ocular area of the face and shorter mandibular spout (Wetzel and Koch 1973; Wetzel and Avila-Pires 1980). Listed below is the average size and weight of an adult Bradypus variegatus (the geographic range of animals studied is from Nicaragua to Brazil), (Wetzel and Koch 1973; Wetzel and Avila-Pires 1980): Habitat Bradypus variegatus prefers trees with large crowns and selects them based on the amount of time the crowns are exposed to sun (Montgomery and Sunquist 1978). This behavior is related to its variable body temperature in which the genus Bradypus thermoregulates its body by moving into the trees when its hot and increasing its exposure to the sun when its cold (Montgomery and Sunquist 1978). It favors lower elevation humid forest conditions and is strictly arboreal. On occasion, Bradypus variegatus does leave the trees and crawls along the forest floor or swims in the flooded forest to find other trees for food. It has difficulty crawling but swims well ( Rodrigues; Britton 1941; Worman 1946; Tirler 1966), although it has never been known to dive into the water. Little change in climatic conditions and high light intensity are both factors that restrict Bradypus variegatus to this particular habitat.

A three-toed sloth Photograph by Joel Sartore Three-Toed Sloth Profile Sloths are identified by the number of long, prominent claws that they have on each front foot. There are both two-toed and three-toed sloths. All sloths are built for life in the treetops. They spend nearly all of their time aloft, hanging from branches with a powerful grip aided by their long claws. (Dead sloths have been known to retain their grip and remain suspended from a branch.) Sloths even sleep in trees, and they sleep a lot—some 15 to 20 hours every day. Even when awake they often remain motionless. At night they eat leaves, shoots, and fruit from the trees and get almost all of their water from juicy plants. Sloths mate and give birth while hanging in the trees. Three-toed sloth babies are often seen clinging to their mothers—they travel by hanging on to them for the first nine months of their lives. The three-toed sloth emits a long, high-pitched call that echoes through the forests as "ahh-eeee." Because of this cry these sloths are sometimes called

67. Sloth Introduces four species believed to have inhabited the United States at the end of the last Ice Age. http://www.museum.state.il.us/exhibits/larson/sloth.html

Ground Sloths Four species of ground sloths inhabited the United States at the end of the last Ice Age. These were Jefferson's ground sloth ( Megalonyx jeffersonii ), Laurillard's ground sloth ( Eremotherium laurillardi ), the Shasta ground sloth ( Nothrotheriops shastensis ), and Harlan's ground sloth ( Glossotherium harlani ). Of these four only two, Jefferson's and Harlan's ground sloths, are found in the midwestern U.S. Ground sloths were large relatives of the modern two-toed sloths ( Choloepus spp.) and three-toed sloths ( Bradypus spp.). Unlike modern sloths, which spend most of their time in trees, the ground sloths spent all of their time on the ground. This is fortunate because Jefferson's and Harlan's ground sloth were each about the size of an oxen. All four species of ground sloth had very large claws. However, all were herbivores. They had relatively small, blunt teeth, which they probably used for browsing on trees and shrubs. The shape of their hip bones indicates that they could stand up on their hind legs. This would allow them to reach high up into trees for the best leaves and twigs. The picture above shows a reconstruction of Jefferson's ground sloth from the University of Iowa Museum of Natural History Reconstruction of Harlan's Ground Sloth Harlan's ground sloth is reconstructed as looking quite similar to Jefferson's, but was a grazing form. This reconstruction of a Harlan's ground sloth is in the museum at Mastodon State Historic Site near Kimmswick, Missouri. The Historic Site is located at the Kimmswick Site. This archaeological site is one of the most intriguing sites known dating from the time of the Clovis people.

Giant Sloth The giant ground sloth was one of the enormous creatures that thrived during the ice ages. Looking a little bit like an oversized hamster it probably fed on leaves found on the lower branches of trees or bushes. The largest of these ground sloths was Megatherium which grew to the size of a modern elephant with a weight over five tons. Giant Sloths had very large, dangerous-looking claws. Despite their size they were probably only used to strip leaves or bark from plants. Their teeth were small and blunt in keeping with their herbivore diet. Examinations of their hip bones suggests that they could stand on their hind legs to extend their grazing as high as twenty feet. Were Some Giant Sloths Really Carnivorous?

It takes a month for a sloth to move 1 kilometer! Sloths are arboreal animals, which means that they spend most of their lives hanging upside-down from tree branches. They eat, sleep, mate, and give birth upside-down in the trees. They hold onto tree branches with strong, curved claws that are on each of their four feet Sloths are herbivores. They eat leaves, tender young trees, and fruit. But it's hard to find time to eat during the sloth's busy schedule that includes sleeping about 15-18 hours each day. The main difference between the two-toed and three-toed sloths (besides the number of toes) is that the three-toed sloth is diurnal and the two-toed sloth is nocturnal. Both of the animals are about 1.5 - 2 feet in length. Both species have a stumpy tail.

Jefferson's Ground Sloth This ground sloth ( Megalonyx jeffersonii ) is one of the most unusual of North American Ice Age mammals. Its bones are so peculiar that whenever I encounter an "unrecognizable" large mammal bone in the Old Crow Basin of the northern Yukon, Megalonyx is the first animal I consider. This long-haired, ox-sized mammal was one of several, including the American mastodon ( Mammut americanum ), the giant short-faced bear ( Arctodus simus ) and flat-headed peccary ( Platygonus compressus ), to enter the Yukon and Alaska from southern North America. The main mammalian invasion of Canada came from Eurasia via the "Bering Isthmus". This species is of historical as well as paleontological significance, for Thomas Jefferson's lecture on Megalonyx ("great claw") to the American Philosophical Society in 1797 marked the beginning of vertebrate paleontology in North America. Appropriately, Megalonyx jeffersonii was named for the third president of the United States. Jefferson's ground sloth, the largest known species of

It was about the size of a cow and had shaggy reddish brown fur. It had a long neck and relatively small head. A very large stout tail and powerful hind legs enabled it to rear up and reach leaves on shrubs and trees. Its legs were built in such a way that it would have walked with a waddling motion using the outer sides of its hind feet and the knuckles on its front feet. Distribution Southern parts of North America, especially in the canyons of the southwest.

All five living species are limited to the lowland tropical forests of South and Central America, where they can be found high in the forest canopy sunning, resting, or feeding on leaves. Although two-toed sloths (family Megalonychidae) are capable of climbing and positioning themselves vertically, they spend almost all of their time hanging horizontally, using their large hooklike extremities to move along branches and vines. Three-toed sloths (family Bradypodidae) move in the same way but often sit in the forks of trees rather than hanging from branches.

It is about 50 cm (20") long and weighs up to 4.5 kg (10 lb). Algae, mites, ticks, beetles, and even moths live in the coarse outer coat, which is long, dark, and manelike around its head, neck, and shoulders. Its underfur is fine, dense, and pale. The maned three-toed sloth is restricted to the Atlantic coastal forests of eastern Brazil . It is found in tropical coastal forest, most typically in areas with an annual precipitation of at least 1,200 mm (47"). The maned three-toed sloth can be found in secondary forest habitats. The maned three-toed sloth is found at altitudes from sea level to around 1,000 m (3300'). The maned three-toed sloth eats the leaves, buds, and soft twigs of a few forest trees, especially those of the Cecropia. It comes to the ground only to defecate, or to move to another tree if it cannot travel through the branches. It rarely descends to the ground because, when it is on a level surface, it is unable to stand and walk. On the ground the sloth can only drag itself along by its longer, stronger front legs and claws. Its main defense is to stay still and unnoticed or to lash out with its formidable claws. On the other hand, it can swim well. The maned three-toed sloth is a solitary animal.

All three Sloth species are believed to be descendents of true "Tree-Dwelling" Sloths and considered more common than their arboreal relatives, the Two-Toed Sloth CLICK HERE TO SEE ANIMAL WEBCAMS Sloths are found in the same biological family as Armadillos and Anteaters in a group of animals known as edentates (toothless mammals). Sloths do have cheek teeth but are lacking incisors and canines and they also make use of their very hard lips to help tear up foraged food. Like the Two-Toed Sloth they are medium sized animals typically achieving weights of between 9-20 lbs. with body length anywhere from 21-29 inches. Another anatomical differences between the two Sloth species is Three-Toed Sloths have short stubby tails and nine vertebrae. We have had the privilege to work with Sloths first-hand.

document.write(TODAY); Animal Links Educational Links Link To Us About Us ... Animal Conservation Rainforest Sloth Sloths are medium-sized mammals that live in the Central and South American rainforests. They belong to the families 'Megalonychidae' and 'Bradypodidae', part of the order 'Pilosa'. Most scientists call these two families the 'Folivora' suborder, while some call it 'Phyllophaga'. The sloth got its name from its slow movement, it is not lazy, just slow-moving. The sloth is the slowest mammal on Earth. In total, there are six species of sloth. Family Bradypodidae Genus (Three-toed sloths) Pygmy Three-toed Sloth (Bradypus pygmaeus) Maned Three-toed Sloth (Bradypus torquatus) Pale-throated Three-toed Sloth (Bradypus tridactylus) Brown-throated Three-toed Sloth (Bradypus variegatus) Family Megalonychidae Genus (Two-toed sloths) Linnaeus's Two-toed Sloth (Choloepus didactylus) Hoffmann's Two-toed Sloth (Choloepus hoffmanni) Sloth Characteristics Sloths have a thick brown and slightly-greenish fur coat and are about the size of a cat around 2 feet (61 cm long). Sloths have a short, flat head, big eyes, a short snout, a short or non-existent tail, long legs, tiny ears and sturdy, curved claws are on each foot. They use these claws to hang from trees. Sloths' claws serve as their only natural defence. A cornered sloth may swipe at its attackers in an effort to scare them away or wound them. Despite sloths' apparent defencelessness, predators do not pose special problems. In the trees sloths have good camouflage and moving only slowly, do not attract attention. Only during their infrequent visits to ground level do they become vulnerable.
