See also:MYLODON (Gr. for " See also: Ossicles somewhat resembling large See also:coffee-berries had been previously found in association with the bones of Mylodon, and in Glossotherium nearly similar ossicles occur embedded on the inner See also:side of the thick hide . The coarse and shaggy hair is somewhat like that of the sloths . The remains, which include not only the skeleton and skin, but likewise the droppings, were found buried in grass which appears to have been chopped up by See also:man, and it thus seems not only evident that these ground-sloths dwelt in the See also:cave, but that there is a considerable See also:probability of their having been kept there in a semi-domesticated See also:state by the See also:early human inhabitants of Patagonia . The extremely fresh See also:condition of the remains has given rise to the See also:idea that Glossotherium may still be living in the wilds of Patagonia . Scelidotherium is another genus of large South American Pleistocene ground-sloths, characterized, among other features, by the See also:elongation and slenderness of the skull, which thus makes a decided approximation to the See also:anteater type, although retaining the full See also:series of cheek-teeth, which were, of course, essential to an herbivorous See also:animal . The feet resemble those of Megatherium . A much smaller South American species represents the genus Nothrotherium . In North America Mylodon was accompanied by another gigantic species typifying the genus Megalonyx, in which the fore See also:part of the skull was usually wide, and the third and See also:fourth front toes carried claws . Another genus has been described from the Pleistocene of See also:Nebraska, as Paramylodon; it has only four pairs of teeth, and an elongate skull with an inflated muzzle . All the above genera differ from Megatherium in having a foramen on the inner side of the lower end of the humerus . A presumed large ground-sloth from See also:Madagascar has been described, on the See also:evidence of a See also:limb-See also:bone, as Bradytherium, but it is suggested by Dr F . Ameghino that the specimen really belongs to a lemuroid . Be this as it may, the North American mammals described as See also:Moro pus and Morotherium, in the belief that they were ground-sloths, are really referable to the ungulate group Ancvlopoda . Although a few of the Pleistocene ground-sloths, such as Nothropus and Nothrotherium (= Coelodon), were of comparatively small See also:size, in the See also:Santa Cruz beds of Patagonia few of the representatives of the family much exceeded a See also:modern sloth in size . The best-known generic types are Eucholoeops, Hapalops and Pseudahapalops, of which considerable portions of the skeleton have been disinterred . In these diminutive ground-sloths the crowns of the cheek-teeth approached the prismatic See also:form characteristic of Mega[lo]therium, as distinct from the subcylindrical type occurring in Mylodon, Glossotherium, &c . By many palaeontologists a group of North American Lower See also:Tertiary mammals, known as See also:Ganodonta, has been regarded as representing the ancestral stock of the ground-sloths and those of other South American edentates; but according to See also:Professor W . B . See also:Scott this view is incorrect and there is no See also:affinity between the two See also:groups . If this be so, we are still in See also:complete darkness as to the stock from which the South American edentates are derived . See W . B . Scott, See also:Mammalia of the Santa Cruz Beds, See also:Edentata, See also:Rep., See also:Princeton Exped. to Patagonia, vol. v . (1903—1904); B .
