Mammoths are prehistoric monsters of the same era.

At the same time as mammoths, there are other prehistoric monsters: hairy rhinoceros, bighorn deer, serrated tiger, cave lion, cave bear, cave hyena, Siberian bison, subgenera or genus of ancient diamond image, giant jackal, and Shiva beast (Shiva beast).

Mammoths, also known as mammoths, are animals that adapt to the cold climate. It used to be one of the largest elephants in the world and one of the largest mammals living on land, among which the grassland mammoth weighed 12 tons. Mammoths are tall and strong, with thick legs, four toes on their feet and a big head. Among them, the ivory of the female elephant is generally 1.5 to 2 meters. The average length of male mammoth ivory is 2.2 to 2.5 meters. Individuals can approach or even exceed 3 meters. It is covered with golden yellow, reddish brown and grayish brown fine long hair, with thick skin and a thick fat layer, with a thickness of 9 cm [1]. They live widely in the northern part of Eurasia. About 100 1000 years ago, mammoths went extinct one after another, which was regarded as a sign of the end of the ice age. Frozen bodies have been found in frozen soil and ice in Alaska and Siberia more than once [2]. On May 7, 20 16 local time, archaeologists from the National Institute of Anthropology and History of Mexico excavated a large number of mammoth ivory fossils. It is understood that mammoth ivory fossils were discovered in the Pleistocene period of 20 15 and 12.

Hairy rhinoceros, scientific name: Coelodonta antiquitatis, also known as hairy rhinoceros, is an extinct rhinoceros, belonging to rhinoceros, belonging to Arthropod Rhinosubfamily. The average body length is 3.5 meters, the shoulder height is about 3.2 meters, and the average weight is 4. 1 ton, which is equivalent to the existing Indian rhinoceros and smaller than the white rhinoceros. It is named for its thick hair. Hairy rhinoceros has two flat horns, which can push away snow and eat grass. It also has a thick layer of fur and fat, which can keep warm in cold environment. The hairy rhinoceros lived in the Pleistocene, contemporary with the real mammoth, and survived the ice age. It is active in the northern part of Eurasia and lives with the giant rhinoceros (Plantletooth) belonging to the rhinoceros family. Hairy rhinoceros was once the hunting object of Paleolithic human beings, and its extinction age was only 10000 years, making it the latest prehistoric rhinoceros to be extinct. Sumatran rhinoceros is a close relative of the existing rhinoceros, which still lives in Southeast Asia, but it is an extremely endangered species and is on the verge of extinction.

The bighorn deer lived in Eurasia in the late Pleistocene and early Holocene, from Ireland to the east of Lake Baikal. It is the biggest deer. A genus of ancient mammals. The bighorn deer became extinct about 7700 years ago. A large number of bighorn deer fossils are now on display at the Irish Museum of Natural History in Dublin, Ireland.

After the extinction of the sawtooth tiger, another more successful saber-toothed tiger continued to threaten mankind. Since 5 million years ago, different saber-toothed tigers (saber-toothed tigers with short swords) have evolved a variety of successors, collectively known as saber-toothed tigers, belonging to the same genus.

Cave lion (scientific name: Panthera leo spelaea): also known as the European cave lion, is an extinct cat. Bigger than modern lions, with stout limbs, the average total length is 2.7 meters, the tail length is 1.2 meters, and the weight is 250 kilograms. The latest research shows that the cave lion is not the ancestor of the lion, but closely related to the lion. During the period from 300,000 years ago to 654.38+10,000 years ago, the footprints of cave lions spread all over the grasslands and desert and semi-desert areas in northern and central Eurasia. About 500 thousand years ago, the flower lion was widely distributed in the eastern and southern parts of the African continent. According to the fossil record, some of its members began to "go out of Africa" and evolved independently. The members who entered the northeast of Asia evolved into cubs, while the lion who entered Europe adapted to the mountainous and relatively cold climate and the composition of prey, further increased its size and evolved into a new subspecies-cave lion. According to records, cave lions died out in the last glacier disappearance 10000 years ago. One of the reasons is that it was hunted to find caves as nests with humans, and the other reason is that its main food, the large European wild horses, and the cave lions that lost their food became extinct.
