The mummified bodies of a woolly rhinoceros which perfectly remained in the conditions of permafrost give the chance rather in detail to restore his appearance.

As the era of its existence on Earth falls on the frosting period, no wonder, that the thick skin of an ancient rhinoceros was covered with long dense wool. On a color and texture its wool very much reminded indumentum of the European bisons, the prevailing flowers were brown and pale-yellow.

Wool on a nape was especially long and shaggy, and the tip of a half-meter nosorozhy tail was decorated by a brush from a hard hair. Experts consider that the woolly rhinoceros wasn’t grazed by herds, and preferred to lead the isolated life.

Food of a woolly rhinoceros

At the terrible appearance and the impressive size the woolly rhinoceros was the typical vegetarian. In the summer the diet of this one-hoofed consisted of a grass and young escapes of bushes, during ice cold winter – of wood bark, an osier-bed, birch and alder branches.

From the beginning of an inevitable cold snap when snow covered already poor vegetation, the rhinoceros had to dig out a forage by means of a horn.

Why woolly rhinoceroses died out

End of a pleistocene, comfortable for life of rhinoceroses, became fatal for many representatives of the Kingdom of animals. Inevitable warming compelled glaciers to recede everything farther to the north, leaving plains under the power of impassable snow.

Under a deep snow cover everything became more difficult to find food, among woolly rhinoceroses there were skirmishes for the sake of a pasture on more favorable pastures. In such fights animals wounded each other, quite often wounds were deadly.

With change of climate also the surrounding landscape changed: on a place of water meadows and boundless steppes the impassable woods absolutely not suitable for rhinoceros life grew. Reduction of food supply led to reduction of their number, primitive hunters completed business.

There are authentic data that hunting for woolly rhinoceroses was conducted not only for the sake of meat and skins, but also in the ritual purposes. Already then the mankind proved not from the best party, killing animals only for the sake of horns which at many cave people were considered cult and allegedly possessed miracle properties.

The way of life of a loner animal, low birth rate (1-2 cubs in some years), reduction of the territories suitable for normal existence and an ill-fated anthropogenous factor minimized population of woolly rhinoceroses.

The last woolly rhinoceros died out about 9-14 thousand years ago, having lost obviously unequal fight with the mother Priroda as a great number of others before and after it.
