MAMMOTH (0. Russ. mammot, mod. mamant; the Tatar word mama, See also:earth, from which it is supposed to be derived, is not known to exist)  , a name given to an See also:extinct See also:elephant, Elephas primigenius of See also:Blumenbach . Probably no extinct See also:animal has See also:left such abundant See also:evidence of its former existence; immense See also:numbers of bones, See also:teeth, and more or less entire See also:car-cases, or " mummies," as they may be called, having been discovered, with the flesh, skin and See also:hair in situ, in the frozen See also:soil of the See also:tundra of See also:northern See also:Siberia . The See also:general characteristics of the See also:order PROnoscIDEA, to which the See also:mammoth belongs, are given under that heading . The mammoth pertains to the most highly specialized See also:section of the See also:group of elephants, which also contains the See also:modern See also:Asiatic See also:species . Of the whole group it is in many respects, as in the See also:size and See also:form of the tusks and the characters of the molar teeth, the farthest removed from the See also:mastodon type, while its nearest surviving relative, the Asiatic elephant (E. See also:maximus), has retained the slightly more generalized characters of the mammoth's contemporaries of more See also:southern climes, E. columbi of See also:America and E. armeniacus of the Old See also:World . The tusks, or upper incisor teeth, which were probably smaller in the See also:female, in the adult See also:males attained the length of from 9 to Io ft. measured along the See also:outer See also:curve . Upon leaving the See also:head they:were directed at first downwards, and outwards, then upwards and finally inwards at the tips, and generally with a tendency to a See also:spiral form not seen in other elephants . It is chiefly by the characters of the molar teeth that the various extinct modifications of the elephant type are distinguished . Those of the mammoth (fig . 2) differ from the corresponding See also:organs of allied species in See also:great breadth of the See also:crown as compared with the length, the narrowness and crowding or See also:close approximation of the ridges, the thinness of the See also:enamel, and its straightness, See also:parallelism and See also:absence of " crimping," as seen on the worn See also:surface or in a See also:horizontal section of the tooth . The molars, as in other elephants, are six in number on each See also:side above and below, succeeding each other from before backwards . Of these Dr See also:Falconer gave the prevailing " See also:ridge-See also:formula "(or number of See also:complete ridges in each tooth) as 4, 8, 12, 12, 16, 24, as in E. maximus .

Dr See also:

Leith-See also:Adams, working from more abundant materials, has shown that the number of ridges of each tooth, especially those at the posterior end of the See also:series, is subject to individual variation, ranging in each tooth of the series within the following limits: 3 to 4, 6 to 9, 9 to 12, 9 to 15, 14 to 16, 18 to 27—excluding the small plates, called " talons," at each end . Besides these See also:variations in the number of ridges or plates of which each tooth is composed, the thickness of the enamel varies so much as to have given rise to a distinction between a " thick-plated " and a " thin-plated " variety—the latter being most prevalent among specimens from the See also:Arctic regions . From the specimens with thick enamel plates the transition to the other species mentioned above, including E. maximus, is almost imperceptible . The bones of the See also:skeleton generally more resemble those of the See also:Indian elephant than of any other species, but the See also:skull differs in the narrower See also:summit, narrower temporal fossae, and more prolonged incisive sheaths, supporting the roots of the enormous tusks . Among the See also:external characters by which the mammoth was distinguished from either of the existing species of elephant was the dense clothing, not only of See also:long, coarse outer hair, but also of close under woolly hair of a reddish-See also:brown See also:colour, evidently in See also:adaptation to the See also:cold See also:climate it inhabited . This See also:character is represented in See also:rude but graphic drawings of prehistoric See also:age found in caverns in the See also:south of See also:France . It should be added that See also:young Asiatic elephants often show considerable traces of the woolly coat of the mammoth . The See also:average height does not appear to have exceeded that of either of the existing species of elephant . The See also:geographical range of the mammoth was very extensive . There is scarcely a See also:county in See also:England in which its remains have not been found in alluvial See also:gravel or in caverns, and numbers of its teeth are dredged in the See also:North See also:Sea . In See also:Scotland and See also:Ireland its remains are less abundant, and in Scandinavia and See also:Finland they appear to be unknown; but they have been found in vast numbers at various localities throughout the greater See also:part of central See also:Europe (as far south as See also:Santander and See also:Rome), northern See also:Asia, and the northern part of the See also:American See also:continent . The mammoth belongs to the See also:post-See also:Tertiary or See also:Pleistocene See also:epoch and was contemporaneous with See also:man .

There is evidence to show that it existed in See also:

Britain before, during and after the glacial See also:period . It is in northern Siberia that its remains have been found in the greatest abundance and in exceptional preservation . For a long period there has been from that region an export of mammoth-See also:ivory, See also:fit for commercial purposes, to See also:China and to Europe . In the See also:middle of the loth See also:century See also:trade was carried on at See also:Khiva in fossil ivory . Middendorff estimated the number of tusks which have yearly come into the See also:market during the last two centuries at at least a See also:hundred pairs, but Nordenskidld considers this estimate too See also:low . Tusks are found along the whole See also:shore-See also:line between the mouth of the Obi and See also:Bering Strait, and the farther north the more numerous they become, the islands of New Siberia being one of the favourite See also:collecting localities . The remains are found not only See also:round the mouths of the great See also:rivers, but embedded in the frozen soil in such circumstances as to indicate that the animals lived not far from the localities in which they are found; and they are exposed either by the melting of the See also:ice in warm summers or the washing away of the sea-cliffs or See also:river-See also:banks . In this way the bodies of more or less nearly perfect animals, often See also:standing in the 531 erect position, with the soft parts and hairy covering entire, have been brought to See also:light .
