Beishanlong is a genus of giant ornithomimosaurian dinosaur from the Early Cretaceous of China. The type species is B. grandis, described online in 2009 by a team of Chinese and American paleontologists, and formally published in January 2010. Beishanlong lived at the boundary of the Aptian to Albian stages, around 120 million years ago.[1]
Discovery
Fossils of a partial skeleton were found in northwestern China, in the province of Gansu. According to the description, Beishanlong "is one of the largest definitive ornithomimosaurs yet described, though histological analysis shows that the holotype individual was still growing at its death."[1]
Classification
Beishanlong was closely related to fellow ornithomimosaurian Harpymimus. Together they formed a polytomy with the main ornithomimosaurian branch just below Garudimimus.[1]
