Qiaowanlong (meaning "Qiaowan dragon") is an extinct genus of sauropod dinosaur. Fossils belonging to the genus were found in the Yujinzi Basin of what is today Gansu Province, China. The remains come from a geological formation called the Xiagou Formation in the Xinminpu Group, dating to the late Aptian Stage of the Early Cretaceous.
==Discovery and naming== The holotype of Qiaowanlong, given the designation FRDC GJ 07-14, was discovered in 2007 by a field expedition of the Fossil Research Development Center (FRDC), who were working on behalf of the provincial government of Gansu. One of the vertebrae of the specimen was broken during transport, but the specimen was excavated and moved to the Gansu Provincial Bureau of Geo-exploration and Mineral Development where they were prepared over the course of the next two years. The description was finally published in 2009 in the Proceedings of the Royal Society B by the Chinese scientists Hai-Lu You and Da-Qing Li.
