Please tell me the habitat of mammoths?

Answer 1

Woolly mammoths (Mammuthus primigenius) are often considered to be symbolic of the last ice age (Quaternary the last 2 million years) because of their large size, broad geographic distribution, relative abundance during the last glaciation, and adaptation to cold environments.

A great deal is known about the appearance of these hairy elephants as a result of the discovery of several well-preserved carcasses in frozen ground in Siberia. Other information has come from the study, in European caves, of many detailed carvings, engravings and murals by Stone Age (Paleolithic) artists. Woolly mammoths grew to the size of Asiatic elephants (about 3 m high at the shoulders) and had similar teeth. Their cheek teeth were massive, comprising a large series of tightly appressed enamel plates filled with softer dentine, all surrounded by cementum, which anchored the teeth in the jaw. As these teeth wore, the enamel ridges stood out and were excellent grinding mills for the relatively tough, dry grasses on which these animals habitually fed. As in modern elephants, during a complete lifetime six molar-like teeth developed in each side of each jaw, making 24 teeth in all. Of the six sets of teeth, never more than two were in use at the same time, because there was not enough space in the mouth. Successive teeth grew forward from the back of the jaw replacing earlier, smaller teeth as they wore, moved forward, and dropped out.

The coats of woolly mammoths were similar to those of muskoxen, consisting of long, (up to 90 cm), dark guard hairs and fine underwool, underlain by dark-grey skin and an insulating fat layer, which in some cases was up to 90 mm thick. Evidently woolly mammoths, like muskoxen, moulted in summer.

Other features characteristic of this species were: a high, peaked head that appears knob-like in many cave pictures, a high hump resulting from the long spines of the neck vertebrae (possibly accentuated by fat deposits and thick hair), a trunk (1) shorter than those of the living Asiatic or African elephants (Elephas maximus or Loxodonta africana), and large (up to 4.2 m), elaborately curved tusks. The tusks of females are smaller than those of males. The undersides of the tusks often show wear, suggesting that they were used in scraping snow and ice off vegetation or were worn against the ground during feeding. Rarely, while one tusk developed to normal size, the other remained a mere stub perhaps due to damage in youth or to abnormal genetic control. Elephant tusks are, in fact, only transformed second upper incisor teeth.

Woolly mammoths were first recorded in deposits of the second last glaciation (possibly 150,000 years ago) in Eurasia, and were derived from steppe mammoths (Mammuthus trogontherii). As time progressed, several changes occurred in the cheek teeth of woolly mammoths. The series of enamel plates became more numerous and crowded and the tooth enamel became thinner. Apparently, at the same time, the tusks became more curved and body size decreased. Such changes were advantageous in chewing tougher tundra vegetation, and probably the decrease in body size (accompanied by reduction of extremities such as the ears and trunk) and development of a thicker pelt enabled the mammoths to survive under increasingly cold conditions.

Remains (especially the durable molar teeth and tusks) of this species have been found in the northern parts of Eurasia and North America. Woolly mammoths probably originated in north-central Eurasia, spreading westward to England and Spain, and eastward via the Bering Isthmus (2) to the tundra-like regions of North America. During the last glaciation, when most of Canada was covered by ice, the species was isolated in refuges north and south of the ice sheets. In the northern area, one of the best preserved specimens consists of much of the front part of the body of a young woolly mammoth from Fairbanks Creek, Alaska, tentatively radiocarbon dated at about 21,000 years old. In life this baby, called "Effie", would have weighed about 100 kg. One of the best Canadian specimens from this area is a skeleton from Whitestone River, Yukon Territory (Figure 2). The mammoth died there about 30,000 years ago, according to a radiocarbon date. In the southern refuge, remains of woolly mammoths have been found in the southern parts of British Columbia, Alberta, Saskatchewan, Manitoba and Ontario, in addition to North Dakota, South Dakota, Minnesota, New York, Virginia and the Atlantic continental shelf off Virginia.

The habitat of the woolly mammoth is clearly indicated by its physical appearance and eating habits. All evidence points to its adaptation to cold climate. Generally in North America its remains are reliable indicators of deposits of the last glaciation (about 90,000 to 10,000 years ago) and tundra-like conditions: tundra, tundra-boreal forest margin, or cold loess-steppe (an environment resulting from massive deposits of fine windblown dust at the edge of ice sheets).

In 1977, the well-preserved carcass of a baby woolly mammoth, subsequently named "Dima", was recovered from permafrost on a tributary of the Kolyma River in northeastern Siberia. It was 115 cm long by 104 cm high and, at death, weighed approximately 100 kg. Chestnut-coloured hair was preserved, particularly on the lower parts of the legs. According to radiocarbon dating, the animal died about 40,000 years ago. "Dima's" internal organs do not differ significantly from those of living elephants, but its ears are only one-tenth the size of those of an African elephant of similar age (7 to 8 months).
Woolly mammoths could not cope with the rapidly changing environment and increasing human predation toward the close of the last glaciation, and most became extinct about 11,000 years ago. However in 1993 came the startling announcement that dwarf woolly mammoths radiocarbon dated between 7,000 and 3,700 years ago lived on Wrangel Island. So while the pyramids and Stonehenge were being built in Egypt and England respectively, dwarf mammoths roamed the relic mammoth steppe on this small island off the coast of northeastern Siberia!

Answer 2

Woolly Mammoths Habitat

Answer 3

they used to be everywhere, migrated to colder grassy climates. i saw a special in tv a while back. they talk about the jarkoff mammoth... and entire mammoth frozen .... they removed it, and are carefully melting it to release the entire body from ice, have already found many cool things about it they never knew before.... it was on history channel, or discovery.. it was a two part program......i think it was near russia or somewhere over that way... sorry geography is not my strong suit...

Answer 4

Mammoths ranged freely on the ice caps that extended down to northern Virginia.

Then man came to this Continent and exploited these wonderful creatures to extinction and polluted this country to the point where it caused the ice caps to start to retreat.

And they have been retreating ever since that day. We need to restore these ice caps to their pristine condition, there natural condition before man came to this country. We need to have the ice 7,000 ft thick over new york city to restore the balance of the Earth.

And anyone who disagrees with me makes their money from big oil and can't be trusted.

Answer 5

I saw a herd of them grazing just the other day. They use them for organic cheese, you know. Good cheese comes from happy mammoths and happy mammoths come from California!

Answer 6

Planet Earth... mostly in the North before the Ice age that we are coming out of killed them all... Global Climate Change really, really sucked for them

Answer 7

i actually, incredibly desire the greater youthful-earthers had no longer hijacked the creationist place in this debate, despite if i think of evolutionists like it that way, because of the fact it incredibly is lots less difficult to defeat. My contemporary place: The earth is over 4 billion years old. yet i'm going to offer you 4 /trillion/ years, and depend continues to be no longer likely to administration itself into molecules donning gigabytes of suggestions and sophisticated metabolic micro-factories with interdependent aspects. (btw, that's the very difficulty that led former atheist Antony Flew to bypass deist.) have been that ever going to ensue below the situations that existed on the very early Earth, it might have taken many orders of fee longer. (And please do no longer quote the Miller-Urey experiments, previously shown irrelevant.) The Hebrew observe for "day" in Genesis a million would properly be comfortably translated as "epoch." (It replaced into rather finished so in numerous different biblical contexts.) God created new creatures to replace the masses of species that went extinct over those long sessions of time. youthful-earth creationists are compelled to hotel to extraordinary, ridiculous theories to reconcile the observational information with their specific doctrine of soteriology. ::EDIT:: If we "uneducated" engineers felt at liberty to extrapolate our documents interior the way pronounced via kmankman4321, the finished developed worldwide would be in mortal possibility. it is likewise been my remark that biologists often are somewhat susceptible in arithmetic, and practically as susceptible of their awareness of layout. They do tell a competent tale, although. (and that they supply the impact of being inspired via the interest "billion.") ::EDIT 2:: Lion of Judah: paste lots?
