The cold and dry plateau of Tibet in Southwest China used to be a warm andhumid rainforest 40 million years ago, scientists from China, India and the UKrecently discovered, saying that it offers critical evidence of the plateau'sancient environment.
The scientists found a Tibet amber and proved it was the fossil resin of anancient dipterocarpaceae, the representative plant of Asian rainforests, whichis key to proving the existence of Tibet's ancient rainforests, according to arelease provided by the Nanjing Institute of Geology and Palaeontology ofChinese Academy of Sciences, which participated in the research, to the GlobalTimes on Thursday.
The Tibet amber, originally located less than 1,300 meters above sea level,is derived from the representative plant of Asian rainforests, said Wang Bo,researcher of the Nanjing Institute of Geology and Palaeontology and programinstructor.
Wang's team worked with their counterparts from Britain and India.
At that time, Tibet had a relatively low sea level and so the forest formedbecause of warm steam from the Indian Ocean, Wang said.
He explained that the Tibet forest resembles Xishuangbanna in SouthwestChina's Yunnan Province, one of the most famous rainforests in China, whichexperiences close to tropical climate.
