Many ancient marine animals have been found on the steep cliffs or deep valleys of the HimalayasBotanyFossils, including trilobites, graptolites, gastropods, brachiopods, nautilus, ammonites, lamellibrants, corals, mosses, sea urchins, sea lilies, ostracods, foraminifera, algae andfishLong, etc. These fossils show that the Himalayan region was once a vast ocean, which emerged from the ancient sea.
So, how did the vast ancient sea become the most magnificent mountain in the world? It is the result of the rise of the earth's crust that causes all this.
Fossils of Quercus alpina and Quercus felis, which grew millions of years ago, have been found on the north slope of Mount Everest at an altitude of 5700~5900 meters. These plants are still growing in many places with an altitude of 2200-3000 meters in southwest China. Although the climate conditions and the growth environment and height of these plants millions of years ago are not exactly the same as those of today, it can still be roughly estimated that the Himalayan region has increased by about 3000 meters over the past million years, with an average increase of about 30 meters every 10000 years.
