Research on the diversity of shape and structure of avian tarsometatarsus,not only did it present evidences to realize the ecological habit of birds of different species,but made the knowledge of functional behavior of avian hindlimbs perfect progressively also.

不同类型鸟类跗跖骨的形态多样性分异反映了鸟类对外界环境的选择性适应。1鸟类跗跖骨的特征1·1鸟类跗跖骨的组构在鸟类后肢骨骼系统中，其下端的跗跖骨为一块愈合完整的骨骼，这亦成为鸟类特有的骨骼结构，与其他四足动物(跗骨、跖骨由多块分离的骨骼组成)明显不同，鸟类由于飞行使得

The analysis of TOC andδ13Corg benefits from Well Chao-73, indicating that they response well enough to the Cretaceous paleoenvironment and paleoclimate. During the sedimentary period of Quantou formation to Qingshankou formation in Songliao basin, the water tends to rise and becomes anoxic, and the deoxidized water leads to the organic matter massively preserved. The paleoclimate changes from torridity and aridity to warmth and humidity, with the temperature evidently descengded, then ascended in a litter range. The result is basically consistent with paleoclimate by the palynological analysis.

朝73井TOC、δ13Corg有机地球化学指标的分析结果表明，TOC、δ13Corg的变化对该沉积时期的古环境、古气候也有很好的响应，该沉积期湖水位不断上升，湖生生物逐渐发展并繁盛起来，水体含氧量减少，湖底有机质的保存环境逐渐变为强还原环境，大量有机质被埋藏并保存，而古气候在泉头组/青山口组界线上下由炎热干旱变得温暖湿润，气温有明显下降，但随后又有小幅的上升，与孢粉分析的古气候变化特征基本一致。
