The height of representatives of the Qiaowanlong kangxii species was about 3.3 meters, body length - 12-13 meters. The weight of individuals reached 10 tons. The only known specimen includes the cervical vertebrae, part of the pelvic girdle and several unidentified bone fragments.
Fossil remains were discovered in 2007 in the Yujinzi basin ( Gansu province, China) and were described by paleontologists Yu Hailu and Li Datsing in 2009 [2] [3] .
The name of the genus Qiaowanlong combines the name of the city of Qiaowan (Qiaowan Pinyin ), previously an important fortress city on the Great Silk Road , and the Chinese word moons ( Pinyin long ) - "dragon". The name Qiaowanlong kangxii is given in honor of the emperor, who ruled under the motto of Kansi (1654-1722; according to legend, the emperor once wrote a famous poem about a dragon that he saw flying).
Qiaowanlong is recognized as a close relative of the genus Sauroposeidon ( North America ). In 2013, it was transferred from the family brachiosaurids to the treasure Somphospondyli [4] .
