    辽西义县组奔龙类化石一新种

    A new species of dromaeosaurids from the Yixian Formation of western Liaoning

    • 摘要: 在辽宁西部义县头台的义县组中新发现的1件奔龙类化石标本,显示出许多中国鸟龙属(Sinornithosaurus)所具有的特征,如上颌骨眶前窝侧面具有装饰性凹坑、前颌骨齿无边缘小锯齿、齿骨后缘二分叉、指节Ⅲ-1略长于指节Ⅲ-2的2倍、?骨Ⅲ部分窄?型形态等。但其头骨的部分骨骼与千禧中国鸟龙(S.millenii)有明显的区别前颌骨主体部分相对较高,其长仅稍大于其高,前颌骨角大,前颌骨上颌突与鼻突均很长,上颌骨不参与外鼻孔的构成,上颌骨窗相对较小且为圆形,方颧骨上升突明显长于颧骨突,齿骨长高之比小等。此外,新标本肠骨的耻骨柄前后方向的宽度小于髋臼宽度。这些不同之处表明,义县头台的标本应为中国鸟龙属另一新种,将其命名为郝氏中国鸟龙(新种)(S.haoianasp.nov.)。
