青藏高原第一个含哺乳动物化石的石灰岩溶洞,坐落在横断山脉北端的西麓、西藏江达县德登区俄折巩的山坡上。在这莽莽青藏高原上发现古脊椎动物化石,如同大海捞针一样是非常不容易的。从传说发现化石这是几年前的事,活跃在西藏东部江达县德登一带的地质队中有位名叫班久的藏族青年工人回忆起童年时代老人们常讲的两段故事:很久以前,西藏江达县俄折巩的珠日拉(藏语意为“龙的山”)有两条大龙和几条小龙,因天旱无雨,死在洞中。听老年人讲:古代有位藏族英雄叫格萨尔王,曾带领千军万马从青海打到这里,把路上阵亡的将士和马匹都埋藏在洞 The first mammalian fossiliferous limestone cave in the Qinghai-Tibet Plateau is located on the western slope of the northern end of the Hengduan Mountains and on the slopes of the Ogun Gong in Dedeng District, Tibet. It is not easy to find fossils of ancient vertebrates on the vast Qinghai-Tibet Plateau, just like finding a needle in a haystack. From the legend that fossils were discovered a few years ago, a Tibetan youth worker named Banjiu, who is active in the geological team in Dendang, in eastern part of Tibet, recalls two stories often told by old people in his childhood: In the past, there were two large dragons and several small dragons in Zhu Rila (Tibetan meaning “Dragon’s Mountain”) in Oggygong, Tibet, where they died in the rain and died in the cave. Listen to the elderly say: ancient Tibetan hero called King Gesar, who led a mighty force hit here from Qinghai, the soldiers killed on the road and horses are buried in the cave
