近日,以我国古生物学家邢立达为首的研究团队在白垩纪琥珀中发现了古鸟类的翅膀,保存的标本和其生前的样貌几乎一致。这两件标本跨越了将近1亿年的时光,也让人类第一次这样细致地观察到已经灭绝了数千万年的反鸟类。同为恐龙的后裔,反鸟和现代鸟类互为姐妹类群,了解它们对于我们理解鸟类的演化过程具有重大意义。 Recently, the research team led by Xing Lida, a paleontologist in our country, discovered the wings of ancient birds during the Cretaceous amber. The specimens preserved are almost the same as their ancestors. These two specimens spanned nearly 100 million years, and for the first time in human history, we have carefully observed the anti-birds that have been extinct for tens of millions of years. As a descendant of the dinosaurs, anti-birds and modern birds are sister groups and understanding them is of great importance for us to understand the evolution of birds.
