The Subashi Formation (Chinese: 苏巴什组) is a Late Cretaceous (Campanian to Maastrichtian)[1] formation from the Xinjiang Autonomous Region of western China.[2] Initially described by Dong Zhiming in 1977, the formation contains remains of Tarbosaurus which were initially described as a separate taxon Shanshanosaurus huoyanshanensis. Remains of a sauropod, likely Nemegtosaurus, and a hadrosaurid, likely Jaxartosaurus, have also been found.
The formation is located in the Flaming Mountains region of Xinjiang, north of the Turpan Depression. It is not far from Lianmuqin Town of Shanshan County,[3] and is presumably named after the village of Subashi ( [ ⚑ ] 42°55′11″N 89°44′36″E / 42.91972°N 89.74333°E), which is located some 15 kilometres (9.3 mi) to the west of Lianmuqin, in Tuyugou Township (吐峪沟乡).
