    豫西栾川地区晚白垩世秋扒组一新的驰龙类化石

    New dromaeosaurid dinosaur from the Late Cretaceous Qiupa Formation of Luanchuan area, western Henan, China

    • 摘要: 根据以下特征,建立驰龙类恐龙一新属新种——河南栾川盗龙(Luanchuanraptor henartens/sgen.et sp.nov):牙齿后缘每5mm有24个小锯齿;前部背椎椎体具有小的椎体侧孔;后部脉弧的前后突短且为三分支;最后部的尾椎体的椎体前突拉长且包裹与其相邻的前部椎体,两椎体前突之间夹有低的刀片状的神经棘;乌喙骨的内面强烈凹陷;肱骨骨干直,肱骨三角脊几乎占肱骨长度的前部一半。河南栾川盗龙代表除在亚洲戈壁地区及中国东北地区之外发现的第一件驰龙类化石标本。

       

      Abstract: A new dromaeosaurid dinosaur Luanchuanraptor henanensis gen. et sp. nov. is erected based on the following characters:about 24 posterior serrations per 5 millimeters on the posterior carnia of teeth; the proximal and posterior extensions of the haemal arch are short and trifurcated; the elongated prezygapophyses of the distal-most caudal vertebrae wrapped the preceding vertebra and the caudal vertebrae bear a low, blade-like neural spine between the prezygapophyses; the medial surface of the coracoid is strongly concave; the shaft of the humerus is straight and the deltopectoral crest extends over almost the proximal half of the humerus. Luanchuanraptor henanensis represents the first dromaeosaurid dinosaur found outside the Gobi region and northeastern China in Asia.
