40 million years ago, the geographical environment in Tibet was completely different
Amber pieces discovered in the Autonomous Region of Tibet, in southwestern China, suggest that about 40 million years ago, there was a tropical forest, according to one study conducted by a joint international scientific team from China, was recently published in the scientific journal "Palaeoworld".
Amber has been discovered in the Lunpola Basin in Tibet and comes from two-horned trees, which are currently found only in the Asian rainforests.
This fact shows that 40 million years ago, the geographical environment of Tibet was completely different.
On the basis of biosynthetic studies and previous studies, scientists believe that at an altitude of 1,300 meters, there was a tropical rainforest in central Tibet.
However, an apparent soil increase was observed on the Tibetan Plateau in Qinghai about 25 million years ago. Plants such as pine and cypress, which can adapt to dry and cold soil, have gradually begun to develop in the area, gradually modifying the natural environment.
