Subashi Formation
Geologic formation in China
From Wikipedia, the free encyclopedia
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.

  Subashi Formation (Bayingolin) | |
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), which is located some 15 kilometres (9.3 mi) to the west of Lianmuqin, in Tuyugou Township (吐峪沟乡).
