There are many, many features that suggest that Xiaotingia and Archaeopteryx are a type of dinosaur called Deinonychosaurs rather than birds.───有很多很多的特征证明着‘郑氏晓廷鸟’和‘始祖鸟’只是一种叫做恐爪龙类的恐龙的种类，而不是鸟。

If Archaeopteryx was a dinosaur, this means flight evolved at least four times in vertebrates: in reptiles, birds, dinosaurs, and most recently in bats.───如果“始祖鸟”是一只恐龙，这意味着飞行能力在脊椎动物史里进化了至少4次：爬行类、鸟类、恐龙，还有最近的一次——蝙蝠。

Some paleontologists now say Archaeopteryx may have been a feathered non-avian dinosaur.───某些古生物学家认为始祖鸟可能是一种带有羽毛的非鸟恐龙。
