Beishanlong
''Beishanlong'' is a genus of giant ornithomimosaurian theropod dinosaur from the Early Cretaceous of China.
==Discovery and naming==
Three fossils of ''Beishanlong'' were in the early twenty-first century found in northwestern China at the ''White Ghost Castle'' site, in the province of Gansu. The type species is ''Beishanlong grandis'', described and named online in 2009 by a team of Chinese and American paleontologists, and formally published in January 2010 by the same Peter Makovicky, Li Daiqing, Gao Keqin, Matthew Lewin, Gregory Erickson and Mark Norrell. The generic name combines a references to the Bei Shan, the "White Mountains", with a Chinese ''long'', "dragon". The specific name means "large" in Latin, in reference to the body size.〔
''Beishanlong'' lived at the boundary of the Aptian to Albian stages, around 120 million years ago. Its fossils were uncovered in layers of the Xinminpu Group. The holotype is FRDC-GS GJ (06) 01-18, found in 2006, consisting of a partial skeleton lacking the skull.〔 The paratypes consist of two specimens found in 2007: one consisting of remains of hindlimbs, the other, FRDC-GS JB(07)01-01, being a pair of pubes. A fourth fossil found in 1999, IVPP V12756 consisting of foot bones, was tentatively referred to the species.〔
