Abstract:  An isolated frontal found at the Tsagaan Teg locality in the Gobi Desert is described. Such features as a short orbital rim and the presence of a sagittal crest indicate that this specimen belongs to Tyrannosauroidea. Because the sediment cropping out at Tsagaan Teg is considered as belonging to the Cenomanian-Santonian Bayn Shire Formation, the present specimen contributes to improving the extremely poor fossil record of tyrannosauroid theropods in the lower Upper Cretaceous. 

摘要： 记述了发现于蒙古戈壁查干泰格地点的一块额骨。短的眶缘和矢状脊的存在等特征表明，该标本属于暴龙超科。查干泰格地点出露的地层被认为属于森诺曼-桑托期的巴音沙拉组，新材料的发现为上白垩统下部非常稀少的暴龙类恐龙记录增添了新的内容。
