我国考察队在喜马拉雅山北坡的希夏巴马峰地区海拔5900米的石缝中,发现了高山栎的树叶化石,这是目前树木化石分布的最高记录。这些化石是150万年前的植物遗骸。现在生存的高山栎,还在喜马拉雅山南坡海拔2700～2900米处生长着。拿化石高山栎和现在活着的高山栎海拔高度相比,相差 China’s expedition team found 5900-meter-high stone crevices in the Xisha Xiama Peak area on the northern slope of the Himalayas and found alpine oak leaf fossils, which is the highest record of tree fossil distribution. These fossils are the remains of plants 1.5 million years ago. Now living alpine oak, but also in the southern slope of the Himalayas 2700 ~ 2900 meters above sea level with the growth. Take the fossil alpine oak and alpine oak now alive compared to the altitude, the difference
