University of Florida News - UF Researchers Find Oldest Bones Of New Giant Ground Sloth Species Eremotherium eomigrans, as named in a recent academic journal article, was the earliest of the giant sloths known as megatheres to have migrated from South America north across the Panamanian Land Bridge, Webb said.

Ground sloth - Wikipedia, the free encyclopedia Ground sloths are extinct edentate (Order Xenarthra) mammals that are believed to be relatives of tree sloths and three-toed sloths. Concerning ground sloths' skeletal structure it may be concluded that ground sloths were very massive animals, plus, very thick bones that end in even thicker joints (especially those on hind legs) would give his appendages tremendous power, their size and fearsome claws, combined with this power, provided a formidable good defence against any predator. Two ground sloths are among the animals that were trapped in the La Brea Tar Pits. en.wikipedia.org /wiki/Ground_sloth   (1050 words)

Sloth - Crystalinks Even so, leaves provide little energy, and sloths deal with this by a range of economy measures: they have very low metabolic rates (less than half of that expected for a creature of their size), and maintain low body temperatures when active (30 to 34 degrees Celsius), and still lower temperatures when resting. Eremotherium eomigrans, as named in a recent academic journal article, was the earliest of the giant sloths known as megatheres to have migrated from South America north across the Panamanian Land Bridge, Webb said.

Brown Throated three-toed sloth The two-toed sloth, a close relative of the three-toed sloth is identified as part of the family Megalonychidae, which recognizes two species Cholepus hoffmanni (Peters 1859), and Choloepus didactylus (Linne 1758). Three ancestral ground sloth families are said to have once existed; Megatheriidae the South American giant ground sloth whose ancestors were arboreal, and the Megalonychidae and Mylondontidae which were always terrestrial ground sloths. According to Webb (1985), one perspective indicates that the giant ground sloth of the late Cenozoic era were highly specialized end members of the phyllophagous xenarthrans while recent tree sloth’s are believed to be more representative of Miocene stages of sloth evolution. bss.sfsu.edu /geog/bholzman/courses/fall99projects/sloth.htm   (3017 words)

BBC - Science & Nature - Wildfacts - Giant ground sloth Giant ground sloths were some of the strangest mammals ever to have lived and resembled no other animal.

Whitley Strieber's Unknown Country Paul Martin, professor of Geosciences at the University of Arizona, is the leading expert on the theory that humans were responsible for the extinction of such animals as the giant ground sloth, and he is skeptical of Oren’s theory. Oren argues that a kind of giant ground sloth could still be alive in the Amazon because the forests offer huge, remote areas providing the isolation necessary for them to survive. Scientists say giant ground sloths were once abundant in the Americas, as evidenced by fossil finds of the creatures in places as far apart as Patagonia in the south to the northwest United States. www.unknowncountry.com /news/?id=1137   (935 words)
