在此，我们描述了来自中国东北部的小盗龙一新种，它提供了关于该属特征的新信息和暗示滑行行为的解剖细节。尽管小盗龙的标本已被发现至少十年，但新化石的完整性提供了额外的形态，突显了这一分类群的独特性。这一新标本名为小盗龙韩青木，它是理解后肢翅膀进化意义的关键。生物体上的四翼结构与现代鸟类有着共同的进化谱系，这表明滑翔运动是鸟类飞行发展的一个阶段。韩青木是已知的中国种最大的微型口蹄类动物，全长约1米，与有毒的中国鸟龙形式密切相关。(C)2012年爱思唯尔与中国科学院南京地质古生物研究所合作。版权所有。
Herein we describe a new species of Microraptor from northeastern China that provides new information on the characteristics of the genus and anatomical details suggesting a gliding behaviour. Although specimens of Microraptor have been known for at least a decade, the completeness of the new fossil provides additional morphology that highlights the uniqueness of this taxon. The new specimen, Microraptor hanqingi, is the key to understanding the evolutionary significance of hindlimb wings. A four-winged structure present on an organism sharing an evolutionary lineage leading to modern birds implies that gliding was a stage in the development of avian flight. M. hanqingi represents the largest known microraptorian from China with a total length of approximately 1 m, and was closely-related to the venomous form, Sinornithosaurus.
