中文摘要	亚洲近颌龙属(Caenagnathasia)首次报道于乌兹别克斯坦的晚白垩世Bissekty组,时代为土伦阶(Turonian)。报道了发现于内蒙古二连盆地晚白垩世二连大巴苏组的一件下颌联合部分,根据以下特征将这件标本归为亚洲近颌龙属:齿骨完全愈合,齿骨愈合部分未向下倾斜,齿骨背侧边缘的前部侧面观略凹,侧面的咬合面具有舌嵴,舌嵴上具有尖状突起,血管槽和相关的孔未延伸到齿骨愈合部分的背面,具有前部的咬合槽。新的标本将亚洲近颌龙的生存时代和地理分布延伸到了中国的坎潘阶(Campanian)。
英文摘要	The oviraptorosaurian theropod Caenagnathasia was first described from the Late Cretaceous (Turonian) vertebrate assemblage from the Bissekty Formation of the Kyzylkum Desert, Uzbekistan. Here we report a partial pair of oviraptorosaurian fused lower jaws, comprising the symphysial region, from the Upper Cretaceous (Campanian) Iren Dabasu Formation of Nei Mongol, China. This mandibular fragment can be referred to Caenagnathasia based on the following shared characters: dentaries fully fused, symphysial portion of dentary not downturned, anterior part of dorsal margin of dentary broadly concave in lateral view, lingual ridge present at margin of occlusal surface on each dentary, lingual ridge bears apical projection, vascular grooves and associated foramina do not extend to dorsal surface of symphysis, and anterior occlusal groove present. This new specimen extends the temporal and geographic range of Caenagnathasia to the Campanian of China.
