Northeast Network October 28 (reporter promised) on the 28th, "disappeared ancient beast - Northeast Bison Head" special exhibition was exhibited in the Heilongjiang Provincial Museum.

Special exhibition "Disappearing Ancient Beasts - Northeast Bison Heads".

According to the staff of the provincial museum, this exhibition is a fossil head of a northeast bison, excavated on the first-class terrace on the bank of the Songhua River in Zhaoyuan County, Heilongjiang. The Northeast bison was moved from Siberia into China and lived mainly between 20,000 and 40,000 years ago. At that time, large areas of grassland and wetlands spread throughout the plains. The average annual temperature is slightly lower than modern, and the grasslands are lush in summer, providing plenty of food for the bison. With the end of the ice age, the temperature warmed, the forest began to flourish, the grassland range was greatly reduced, and the living environment changed; in the same period, human beings began to grow and expand north with the improvement of production capacity, which also occupied the living space of the bison, and eventually led to the complete disappearance of the northeast bison 10,000 years ago.

The Northeast bison has a wide frontal bone, thick horns, and thick long hairs on its body, which can adapt to colder climatic conditions, and is an important member of the famous mammoth in the north, the woolly rhinoceros fauna. It can reach a height of 1.8 meters and weighs more than 1 ton. It has a high hump-like bulge on its back that stores energy and provides the necessary nutrients in times of food shortage; it is good at long-distance migrations as the seasons change. The population of the Northeast bison accounts for an absolute majority of the mammoth and woolly rhinoceros groups, and the population can reach the million level during the boom period.
