Paleontologists are now carefully studying the closest theropod relatives of birds for clues to how this transition occurred.
古生物學(xué)家正在對鳥類的獸腳亞目最近親進行仔細(xì)研究，以尋找這種轉(zhuǎn)化的線索。
Since then, however, scientists have found a number of well-preserved theropod fossils with many more featherlike structures, corresponding to downy feathers and feathers with vanes.
無論如何，從那時開始，科學(xué)家已經(jīng)找到了一定數(shù)量的保存完好的，擁有類似羽毛結(jié)構(gòu)的獸腳亞目恐龍化石，這種結(jié)構(gòu)和羽毛絨還有羽毛葉片符合得很好。
But it is clearly a small, vicious theropod similar to the velociraptors that chased the kids around the kitchen in Jurassic Park.
普魯姆高興地說道。 “但它顯然是一只體型不大卻性情兇猛的獸腳亞目食肉恐龍，有點像《侏羅紀(jì)公園》里在廚房追逐孩子們的那種迅猛龍。”

And don't rule out collecting replicas--Pritzker has a cast of a theropod skull and Myhrvold has casts of all seven known Archaeopteryx, the missing link between dinosaurs and birds.
FORBES: Dig It
The Eubrontes prints were made by theropods—the dinosaur group that went on to produce such nightmares as Allosaurus and Tyrannosaurus—and Eubrontes is already 20% bigger than any theropod track recorded from the Triassic.

There are 10 tracks sites found around Yanguoxia since the first discovery in 1999, in which the site 1 is the largest one including sauropod, theropod, ornithopod and pterosaur tracks. A bird track-bearing horizon also occurs 2m above this level.
甘肅永靖鹽鍋峽自1999年發(fā)現(xiàn)足跡化石以來已經(jīng)共發(fā)現(xiàn)10化石點，其中1號點保存足跡類型最為豐富，包括有蜥腳類、獸腳類、翼龍等足跡化石，且在該巖層面的不到2米的砂巖中發(fā)現(xiàn)有鳥類足跡。
