Environment → The mastodon is different from the mammoth?
Mastodon lived in Africa, Europe, Asia and North and South America. He appeared in the Oligocene epoch (25 to 38 million years ago) and became extinct in less than a million years ago. Mastodon reaches a height of 3 m and was covered with dense hair. His tusks were sent forward almost parallel to each other. Mammoth appeared less than two million years ago and disappeared about 10 thousand years ago. He lived in North America, Europe and Asia. As well as the mastodon, mammoth was covered with thick hair, the top layer of which consisted of long, coarse hair, protects it from the cold. He was larger than the mastodon and reaches a height of 2.7 to 4.5 m. The tusks of the mammoth diverged in hand and curled up.
The gradual warming of the Earth's climate and environmental change in the environment may have been the primary reasons for the extinction of these animals. In addition, they were hunted primitive people.
