简说羽毛化石的研究

自第一枚始祖鸟化石发现以来，鸟类的起源与演化成为了古生物研究的热点之一。有关鸟类的起源问题涉及了恐龙以及早期鸟类的形态结构、飞行以及羽毛等多方面内容。在早白垩世热河生物群以及相邻地区侏罗纪地层发现的许多保存精美的带毛恐龙，中生代的鸟类化石，为鸟类的恐龙起源提供了重要证据，并且使我们对羽毛的起源和演化有了较丰富的认识。笔者主要介绍了带毛恐龙的羽毛化石的研究现状，并结合发育生物学，讨论了关于羽毛的发育和演化问题。

Study on Fossil Feather

The issues about the origin and evolution of the birds have been the hot biological topics since the first discovery of the Archaeopteryx.The question of the origin of birds includes many biological aspects,such as the morphology,flight and feathers.The exceptionally and exquisitely preserved feathered dinosaurs and Mesozoic birds fossils in the Early Cretaceous Jehol Biota and Jurassic deposits in Northeast China provided highly important evidences on the dinosaurian origin of birds,and increased our knowl...
